Power Steering Pump – Jeep Cherokee

My power steering pump started growling at Harlan. When I backed my Cherokee out of the barn last week, there was a huge puddle of power steering fluid on the floor. At first I was not sure it was from my Jeep but after cleaning it up and parking the Jeep back inside again there was another puddle of fluid.

While testing the new trails Saturday, I lost all steering assist for a moment and tagged a tree. I decided to put Scuffy away for the day and let Princess play by her self.

I checked the lines and the reservoir for leaks and found none. It must have been leaking through the pump seal.

I have a 94 parts Jeep but the part number for the power steering pump is different for the 88. I looked at the pump and it appeared to have the same mounting bracket. The reservoir is visibly different but the pump itself looked the same. But they have different part numbers.

In the process of removing the pump from the parts donor XJ, I broke off the return nipple. It was very cold and the hose stuck. The brittle plastic snapped before the hose slipped off.

I removed the reservoir from the 94 pump and inspected the connection point. It mounts in a hole sealed with an O ring. The tank is held on by a couple of tapered clips that come off easily with a hammer and punch.

I removed the pump from my 88 Jeep and noticed that the mounting bracket was exactly the same. The pressure hose looked the same. Only the routing of the return hose was different.

Since the donor reservoir was broken anyway, I decided to see if the tanks would swap. I removed the tank from my old pump and saw that it had the same O ring connection. I simply installed my old tank on the donor pump. I even used the bracket from the donor since it was easier to leave it assembled to the pump.

With it all bolted back up, I filled the reservoir with fluid and started it up. There seem to be no leaks. There was a bit of fluid slung off the belt but I hope that was from the old leak. I will give it a full test run later.

I was very happy to have saved $170 that a new pump would have cost. I was also happy not to have to remove and replace the pulley.

Axle U Joint

Lately I noticed the roar in Janice’s Cherokee was getting louder. The rear wheel bearings have need a change for a while but I keep putting it off.

On the lift I noticed that the right front axle U joint was loose. That was making more noise than the rear wheel bearings so I decided to tackle it first. Also I am very familiar with this job.

I began by removing the wheel and brake caliper. Then I removed the center nut and washer. I then pulled the three hub mounting bolts.

I was very pleasantly surprised at how easily the hub came out. Most of the time I have to hammer these out but this one can out in my hand.

I used a support to hold the axle up while I pulled the axle shaft out. This reduced the amount of gear oil lost from the differential.

I then move took the axle shaft to the vise to swap out the joint. This is a job I have also done many times as evidenced by all the roller bearings on the floor behind my vise.

This joint proved very stubborn to extract. I pressed and hammered and finally got one cap off. I then went to press the cross back through and the other cap must have gotten crooked because it jammed and the cap broke rather than come out.

I used a combination of hammering, pressing and using a punch on the anvil to finally extract the broken cap. The other two caps from the stub axle came out relatively easy after that.

I put the new caps on the anvil and tapped them in to the axle. Then I put in the other two caps. I used the press to move caps in enough to put the C clips on.

I slipped the axle back in and reinstalled the hub. Then I put the rotor back on and the brake caliper. With the wheel back on and the lugs torqued, Janice took it for a test drive and noticed that is was much quieter.

Now I still have to do the rear wheel bearings. I have everything on the shelf, I just have to schedule some time.

Trail Maintenance and Building a new Trail

Building a New Trail

This weekend I decided to do some trail maintenance and build a new trail. The recent had blocked one trail and a couple have been blocked since last spring.

My chainsaw has a bad ignition module so I borrowed my Dad’s chainsaw. His starts and runs much better than mine.

We began by cutting down a tree that was leaning across the trial we call Wedgie. This trail drops into a huge V notch and then makes a steep climb. We also opened up the top of the trail so that the off camber turn over a tree root is optional.

This trail has given Jenny’s Jeep a challenge in the past but now on her new 33” tires she made it across the V notch easily. On the return trip dropping into the notch from the steep side, she did tag her bumper into the opposite bank but she pulled through easily.

Next we reopened the loop off the campsite that goes to the far corner of the property. This trail has been blocked by two fallen pine trees for a while. We sliced a couple of cuts in the logs wide enough to get the Jeep through.

Next we worked on a new trail. This one includes the steepest hill climb we could find. We call this trail Slickery because in the wet leaves it was very slick. On the opposite side of the hill there is a large tree root at the base that makes the beginning of the climb interesting. We left a small log across the trail for an additional challenge.

On Jenny’s first run back up the hill, she spun in the leaves and dug in. She got sideways enough that she could not back down due to a tree. So we used Scuffy’s winch to get her to the top of the hill. On her next run, she carried a bit more speed at the bottom of the hill and made it up easily.

Now we have to work on naming all the trails so we know where we are talking about. Then we will have to put a GPS in a Jeep and make an accurate map.

How To Replace a Leaking Rear Wheel Cylinder in a Jeep Cherokee

How To Replace a Leaking Rear Wheel Cylinder in a Jeep Cherokee

The rear drum brakes on Jeep Cherokees are generally reliable and long lasting. While swapping to disk brakes is a popular modification, the rear drums do a fine job of stopping when they work properly.

One common problem as the brakes age is that the wheel cylinder leaks. The wheel cylinder has two pistons that press out on the brake shoes when the pedal is depressed. The two pistons have rubber cups on them that will wear with age. Also, water can contaminate the fluid and cause the lining of the cylinder to rust.

There are several different wheel cylinders used so make sure you get the proper replacement before disassembling the Jeep. The cylinder for the 9” brakes is different from the one for the 10” brakes and the one used for antilock brakes is different from the one used for non antilock.

Begin by lifting the Jeep and supporting the rear axle. Remove the wheel and tire.

Using a 3/8” line breaking wrench, loosen the brake line where it connects to the wheel cylinder. If the line is stuck, try tightening it a bit before loosening it. Heat can help if it is severely stuck. Use care not to damage the metal line. Use a pan or a rag to catch the brake fluid that drains out.

Remove the two 3/8 headed bolts that hold the cylinder to the backing plate. Remove the brake drum. Loosen the brake shoes slightly if necessary.

Using a brake spring tool, remove the two upper brake shoe springs. Pull the front shoe slightly forward and slip the wheel cylinder out around the axle flange. Clean up and fluid that had leaked into the brake drum.

Slip in the new wheel cylinder. Install the two retaining bolts. Reseat the front brake shoe. Replace the springs using the other end of the brake spring tool. Take care to ensure the cable for the automatic brake adjuster is routed correctly and has not fallen out of place while the tension was off.

Reconnect the brake line. Reinstall the brake drum and adjust the tension.

Add brake fluid to the master cylinder to replace what drained out. Bleed the brakes by having an assistant depress the brake pedal while you open and close the bleeder screw.

With the bleeder closed, have the assistant pump the pedal a few times and then hold it depressed. Open the screw and allow fluid to come out. Close the screw and have the assistant repeat the process. Repeat the process and have the assistant note the firmness of the brake pedal as you observe the amount of air in the expelled fluid.

Once the fluid runs clear with no air, tighten the bleeder screw and install the protective cap. Reinstall the wheel and tighten the lugs to the proper torque. Lower the Jeep and top off the master cylinder before driving.

Forty Nine

Imagine cruising down the interstate enjoying the view through a big glass windshield. The stars are bright and your destination is miles away. You are driving along with out a care in the world. Everything is going well and you expect to arrive at your destination at exactly the scheduled time. Music plays softly in the background and the clatter of the engine combines with the roar of the tires on the pavement to allow you to settle deep into the warm comfortable driver’s seat.

Then suddenly your vision is blurred and glass shatters in front of you. A large lump of something lands in your lap as you try to control your bus and protect the precious cargo of passengers behind you. Someone has just gotten their jollies by dropping a large object from the bridge above you. You safely pull the bus to the side of the road and inspect the damage. Miraculously you are still alive. Just a few cuts and scrapes.

Glass is scattered through out your bus but none of the passengers are seriously injured. Everyone is OK but you will not make your destination on time. And your bus is going to need some serious repairs. It could have been worse. Like it was for a woman a few years ago who had a stone dropped through her from possibly the same bridge. She died from her injuries.

So it could be worse, but still it is pretty bad. What fun it must have been for the hoodlums who tossed the weight into the bus wind shield? Did they even get to see the crash in the darkness? A whole bus load of students returning from a trip are jolted from their peaceful ride by a senseless act.

This story is from this week’s news. A bus load of Lee University students was attacked as it cruised home on I 75 this week.

I read somewhere that life goes through seven year cycles. If so, then this is the end of my seventh cycle. Tomorrow I will be fifty.

I feel like this cycle of my life began with something crashing through the windshield of my life. I was comfortably cruising along in my career as an engineer for Westvaco Corporation. I had comfortable pay. I was good at what I did. People respected me and I was surrounded by friends. While there were many things I did not like about corporate life, I was very comfortable. I had challenges to keep my mind occupied and a comfortable office to go to each day. I was ready to cruise on auto pilot to retirement.

Then, suddenly, my dream was shattered. The plant I worked at was closed. There was some fall out but I was not really injured. Just a few scrapes. The impact reverberated through the other parts of my life.

Suddenly, I was faced with struggling for finances and not feeling very useful. Much of my self worth was wrapped up in being an engineer for Westvaco. When I was not that anymore, I felt like I was nothing.

I tried a few other jobs but none of them gave me any satisfaction. I was not good at them so my self worth went down even more.

My old friends drifted away as they moved on to other jobs. I found my self in a very bad spot. I was alone and felt pretty useless.

In the process of rebuilding myself, I discovered the new thought movement. I discovered it entirely by accident. Or so it seemed.

I began reading books about how to make money and I discovered that there was a common theme in all of them. The idea was that we each create the circumstances that surround us rather than being manipulated by them.

As I studied concepts that were foreign to me such as the law of attraction and the law of mind action, I began to see evidence of their truths. I remembered times when I worked at Westvaco when I had observed this very phenomenon. But not having any basis for causal relationship, I dismissed it like any good engineer would.

I had once made the statement that Westvaco should pay me to be in a good mood because when I was, the presses ran better and if I was in a really good mood, we would set production records. If I came to work in a bad mood, then we had nothing but trouble.

But even after reading the Tao of Psychology, I refused to acknowledge the relationship between my moods and the circumstances. There was no way my emotions could cause outside circumstances was there?

During the last few months at Westvaco, I met a faith healer. The stories he told and the things I observed caused me to believe that there really was more to the universe than what I had learned in school. But I still but my faith in science. But to the true science of mind, just the traditional observational science.

As I studied more and read books by Deepak Chopra, Wayne Dyer, Charles Filmore and others I began to realize that there was something to this science of mind. I began to see that everything I observe is first created in my mind. I also began to understand what Wallace Waddles meant when he said that controlling the mind is the hardest and most import work any man can do.

I am still working on learning to control my thoughts. I often don’t feel that I have the freedom to create with my thoughts. My upbringing in a guilt based religion pops up often causing me to feel that I don’t have the right to even want certain things.

So as I begin my fiftieth year tomorrow, I am moving forward with excitement and wonder. I wonder what will happen next. I have moved way out of my comfort zone and most of my life lines are gone. I will be on my own to create the life that I desire. I can’t rely on anyone to do it for me. I am excited and scared at the same time.

I feel like I have wasted a lot of years getting to this point in life. I have always prided myself on being a fast learner, but in this most important area of life, I feel like I have been very slow on the uptake. Hopefully the pace will pick up and I will learn to release the old constrictions and begin to create a truly happy life that I want.

But first I have to feel like I deserve it.
