So I was studying up on some of the issues that people were having with their center bearing, and what do you know, but mine goes out only a few days later. I took what most people were saying was the best fix and documented what I did. Instead of just replacing I upgraded to the King Headz aluminum combo with the larger bearing. Also I installed the aluminum bearing adapter to try to eliminate many future problems. Even though the pics look as though I have neglected the bearings on the truck, they have all been serviced regularly. I live in SE Idaho so the winters are long and wet and that wreaks havoc on the bearings. I was bashing and noticed after a small jump (nothing much) that the truck was acting like something was stuck in the spur. It would roll and then stop always the same distance, that led me to believe that it was spinning until it hit that spot, then it would bind up.... Enjoy
P.S. I have never done one of these before, so take it easy on me. Also, all of the specs are in the exploded views that come with the truck, so im not going to get to technical here.
So, lets crack this bad boy open and see whats up
First, remove the 4 main screws that secure the rearend to the main chassis. 2 on top 2 on bottom.
My suspicions were correct, there was something stuck in the teeth. I just didn't think it would be one of the ball bearings from the center bearing
There wasn't much damage to either the spur or ring gear, you can see a minor mark where the ball left a small indentation.
Then you remove the slipper clutch assembly. This was easy on mine because the bearing was completely worn out. This takes a little practice, but if you take your time and look to see what may be causing binding issues, you should be able to remove it with ease.
Pretty tough shape, huh. I cleaned and lubed this bearing about a week ago and had less than 4 hours on it.
The carnage from inside the bearing. Notice the melted plastic bearing adapter.
Getting the race out after the bearing has had a failure like this is kind of a challenge, but with a little work it comes out. Notice the first picture where I am using a larger flat head to give the bearing some room to rise, and my small screwdriver isn't prying down on the bearing.
YAY! Why replace, when you can upgrade. Kings Headz center bearing mount and bearing, aluminum bearing adapter, and the other bearings are just replacement wheel bearings.
