Jeep Cherokee Power Steering Hose Replacement
I have replaced several power steering hoses on various Jeep Cherokees. It has gotten to be a pretty straight forward job. See this previous post on how to replace a power steering hose.
Janice’s 1999 Cherokee had been emitting a puff of smoke each time she turned her XJ to full lock. Although there was little sign of a leak on the hose, our experience with the Green Jeep catching fire due to a power steering hose leak made me extra cautious.
I got a new hose and then pulled the electric fan and the air box to make room. I tried using the various 18mm wrenches I had to get the hose loose from the steering box. I have always been successful in the past using an open end wrench. However, this one refused to budge.
I picked up a set of crow foot flare nut wrenches from my local NAPA store. They have a great set of tools in a nice case for around $20. Unfortunately I forgot that the bottom is an 18mm and the top is a 5/8 inch. I bought only the SAE set. The store was closed for the holiday by the time I figured out I also need the metric set.
Jennifer rescued me by searching until she found a set at O’Reilly’s. It is still a nice set for about the same price as the NAPA set but does not have the nice case.
I used the 18 metric crow foot flare nut wrench to break loose the lower line. It took a lot of torque but it eventually broke free. Janice and Jennifer were able to finish taking it out using the 18mm stubby wrench.
I used the 5/8 crow foot to pop loose the upper hose. It was not nearly as tight. I showed them how to put on the O rings on each end of the hose and let them get the lines threaded into place. The lower one always seems to be difficult and takes some patience to get it started.
After the new line was installed, I had them add some fluid and jack up the front of the Jeep. They turned the wheel from lock to lock to bleed the air out of the line. After that, they started the engine and repeated the process.
Once most of the air was out, she turned the wheel to one of the locks and listened for the pressure relief to open. There was a noticeable change in sound as the last of the air purged.
I rechecked the level of fluid in the power steering reservoir and checked for leaks again. Now we all feel much safer driving the Jeep.
