I have an early 99 that the unit bearings are going bad.
What is the difference between the early 99 and the later 99 and up unit bearings ?
Can I update mine to the later units ? What all is different or needs cahnged to do this ?
I've tried searching, but can't find the up front answers for my questions.
There are some differences with front end parts for the early 99 ( like U bolt shape) but I believe the hub would be the same for 99-04. I think the only option you have at the parts store would be if you have ABS up front. Those bearings come with the ABS wire attached.
