Problems with 96 rear end
Hey everyone
New to this site, have a question about my 96 bronco. I bought it in 2000 with 65k at about 75k the bearings in the rear end went out. It now has 107k and the bearings went out again. Any ideas that would cause this to happen again after 30k miles?
I run 31x10.5 tires on the stock rims and I've had a lot of balance issues with two different sets. I get them balanced and a few hundred miles latter I start to get a vibration at around 65 mph. Could that vibration and balance issue be part of the problem? Besides two sets of bad tires what else could cause that? Any help and insight would be much appreciated.

Probably the new bearings weren't mounted right, that would cause the balance issues and the short life of the bearings. Besides that: do you go through a lot of water/mud? wich brand were the bearings you used as replacement? cheap ones could fail rather fast.

Thanks for the response the first time they were replaced buy the local ford dealer so I have no idea what type were used. I live in Oregon so rain and mud are common. A person I trust is now doing it so it should be done right. I just don"t get the vibration problems at speeds around 65mph. I will be intrested to see if that goes away after the bearings are replaced this time.

If the vibration issues don't vanish with the new bearings... STOP driving it and look into the problem further. A drive shaft out of balance or worn slipshaft could also be the culprit and contribute to the early demise of the rear end bearings.

I don't think the cardon will be the one causing troubles here, in any case a bent axis, have you hit any sidewalks with the rear end? like losing traction? that could bent the axis.

On the 8.8 diff, the bearings ride on the axle. The inner race IS the axle! If they go out, they wreck the axle. When replacing them, the standard fix is to put repair bearings on. Those move the bearing about an inch over on the axle. The alternitive is to replace the axle when you install new bearings. Of course, you can only install one repair bearing. Then the axle is scored both places. If you have had them replaced twice and never got new axles, they are gouing to fail fast.
This is the biggest downfall of the 8.8 diff in my opinion. I went to a full float setup because of this. But it costs alot more than new axles.
