Things you will need include; a jack, a spare shaft, a 13mm twelve point socket or wrench, a 36MM socket and something to turn it. You will also need the appropriate tools to remove your wheel and brake caliper. These vary from year to year and depending on your accessories. A hammer and a spare set of hub bolts will be helpful as well.

If your wheels have open centers, begin by removing the cotter key and the center nut on the axle shaft. This nut is very tight when tightened to specs. You will need either an impact wrench if you have on-board air or a long handled pull bar on the socket. If you have a closed center wheel, you will have to remove the wheel and have someone hold the brake while you loosen the nut.

Support the vehicle and remove the wheel. Remove the brake caliper and support it on the control arm. Try not to let it hang by the hose. Next, remove the brake rotor.

Using a 13mm 12 point socket, remove the three bolts that hold the bearing to the knuckle. The bearing will likely be stuck in the knuckle. My favorite way of removing it is to screw in some disposable bolts that have the same thread and hammer on the bolt heads. Once you hit the bolt head with a hammer, you will not be able to put a wrench on them in the future. I carry a set of bolts for this purpose in my axle repair kit.

If you don’t have spare bolts, you can still tap the bearing out using a hammer and pry bar. Try not to hit on the wheel mounting flange however as this can damage the bearing.

Slip the bearing out and then remove the broken shaft. If part of the shaft remains in the axle housing, use a magnet to remove it. If you can not pull it out with a magnet, you can also remove both shafts and push it out with a stick or long metal rod.

If you have jacked up the side you are working on high enough, you will not spill any axle grease. Even with it level, there should only be a small loss.

Slip in the spare shaft and check for any other damage. Put the bearing back in place and secure the three bolts. Place the rotor back on the hub and secure the brake caliper. Mount the wheel then tighten the center axle nut. Replace the retainer clip and cotter key.

Pump the brake pedal a couple of times to remove any slop that may have been introduced by removing the caliper before attempting to move the Jeep. Now get back to wheeling!

I have dealt with many different ways to balance tires since I started mounting my own tires several years ago. I have had very good results using a simple bubble balancer and lead weights clamped to the rims.

I have considered purchasing a spin balance machine on several occasions but the cost of the machine has deterred me considering the small number of wheels I balance in a year. I can pay to have several tires balanced for the cost of a machine. Also, for most tires my bubble balancer provides acceptable results.

I have studied various methods of automatic wheel balancing for years as well. As the tire wears, the balance changes. And short of taking the tire off the Jeep and rebalancing it, there is nothing else that can be done using the clam on wheel weight method.

I have looked at the rings full of mercury that bolt on the back of the wheel. I have studied the sand and ceramic dust methods used on semi trailer tires. However the simplest method for me to implement would be to add a liquid to the tire.

Looking at the mathematical proof of the physics behind the sand method, I theorized that any fluid would do the same. The material tends to move to the light spot as centripetal force takes over automatically balancing the tire as it rotates.

This week I came across the idea test subject. In the past I was fighting other vibrations at the same time such as bad bearings or U joints. This time however, my truck was running smooth and I had a tire with a big chuck of rubber missing.

Running the tire with no weights produced a huge bounce that could be felt at speeds over 40mph. The Jeep was un drivable at over 60MPH.

The first test was to balance it with conventional lead weights in the bubble balancer. It took slightly over 280 grams of lead on the rim to balance the tire. It was difficult to get that much lead on the wheel and on the test run one of the weights came off. However it did produce a smooth ride.

The next test was to replace the lead with a liquid. I did not want to use water as in freezing conditions it would make a block of ice in the low part and create a huge imbalance. I chose instead a 50/50 mix of antifreeze and water.

I popped the bead on the tire and poured in 290 grams of the balancing liquid. I remounted the tier and took it for a test run.

The initial test run showed a nice smooth ride. I was not able to exceed 60MPH on the test run due to road and traffic conditions but the ride was noticeable smoother than with the lead weights.

I plan to further test the liquid wheel balancing method to see if it will automatically balance all wheels. The math shows that it will work with tires that have dynamic balance problems as well. I can’t deal with these on my bubble balancer so if the liquid method of automatic wheel balancing works, I will not ever have to buy a balancing machine.
