Do you have access to a hydraulic press to remove the bearing? Has this been done by a work shop and it is still faulty? If so they should warranty their work.

No I do not think so. My husband will be doing it. Have brought it in three times in five years and just cannot afford to bring it in again. He is worried about if he has to remove gas tank to do it and just how exactly to do it? He has worked on cars all his life but is unsure about this vehicle.

I seriously doubt that he is going to be equipped to do this himself.

His buddy has a lot of tools. All he does is work on vehicles and stuff. I am sure and hopeful that they can get it done. We will see, but it was nice to get the information to know for sure what to do. Thanks again. I will have him look at this when he gets home and if he has questions I will have him write. Thanks

You can always just send the axle to a work shop to do the bearing change, and do the rest at home.

So does he have to take the differential cover off to get to the retainer plate? Which means take the gas tank out? Like a Chevrolet truck.

No, this one is all done from the wheel end. The big problem is that the bearings are pressed onto the axle and will require a hydraulic press to get them off and the new ones on.
