I have a 2002 2500hd 4x4 with the 6.0, It has a 6in lift with 35in tires. I changed the passenger side rear wheel bearing twice in the past 6 months. I replaced both inner and outer bearings and the seal each time. After a couple weeks of driving it starts to leak rear end fluid and the bearing goes bad shortly after. Once it starts to leak i keep the rear end full of fluid. I could be installing the bearings or seal wrong but i wanted to check to see if anyone has had a problem with them wearing out really quick. I dont know if it could be the carrier or if im doing it wrong. any info would help thanks.

You may have a worn or bent axle. I had a simular problem with my lifted 'Burb and it was a worn axle. If I remmember it had about 110,000 miles on it. These big tires DO wear out parts sooner.

You should be able to feel the axle where the seal runs and if it has a groove it is worn, I have also seen seals put in wrong or when sliding the axle in the seal gets damaged. Also check for burrs or rough spots as that can also cause problems.

changed the wheel bearings and seal today and i think i found the problem. I had a old timer mechanic tell me to check to see if my diff vent line was cloged. i cleaned the line and blew it out. I will be keeping a eye on it and ill let you know if she holds up. thanks again for the help
