First off thank God for Cherokeeforum as I've probably used more than my quota of help needed posts lately!!! Ok, the basics....89' Cherokee 4wd...... looks like I've worn out another set of unit bearings after only about 10k miles 😡😖. Can you guys give me some things to look for that might cause this (aside from cheap bearings)? I believe I bought Timkens last time but will DEFINITELY be buying them the next go-round!!! Happy Independence Day.....hope you all get to enjoy it with family and friends!!

 

1. Bearing Quality
2. Proper pre-load (torque on the axle nut)

 

i'm pretty sure up here, timkins have a lifetime warranty. you might want to check that.

 

Not torquing the axle nut properly would do it. 175ft-lbs.
