How do you Do Maitanence on the Front Wheel Bearing on a 1993 Pontiac Transport?

Answer 1

These vehicles have no servicable possible bearings. This is because GM, with their self preservation tactics have used sealed bearings in the hub, and you need to replace the entire hub, bearings, and speed sensor all in one, when anything goes wrong at some hundreds of dollars. Mine has ABS, and would have been just under six hundred dollars if I'd let them get away with their game. I bought used for one hundred and fifteen dollars, and I have put many thousands of miles with no detering consequences. The ABS portion is just a simple voltage generator, that stops producing electricity when the wheel stops turning (ie. locked), and this signal ( or lack there of) is interpreted by the computer, and it in turn causes some of the hydraulic pressure to be released at that wheel so it turns again. This is all happening at the speed a computer is capable of, and it is really not rocket science. I drove through some water that leaked past the back bearing seal, and caused rust to develop. When I took it apart it was full of rusty watery grease. It's symptem was that, that wheel caused a rumbling sound as I was driving. I also can add that I broke the bolts on two different cheap three jaw pullers, before I got a puller designed for the job. The bearing was actually rusted onto the axle. One might be able to match the bearings at a supplier such as, Bearing and farm supply, but the rust had done too much damage on mine, before I'd realized it had occured.
