I need new rear wheel bearings on 87

[gr8fl4porsche]

I need to replace my rear wheel bearings on the 87.

I am trying to decide if I should pull it all apart, have the bearings pressed out and in, put it back together and have the fresh alignment redone vs have the shop do the work with the hubs still on the car.

Is it possible to do it myself and retain the alignment settings?

The rear alignment is not affected. I have done this job twice using the Sir Tool bearing remover/installer I got from Pelican. The job is made easier with this tool but still takes a while. You don't have to remove the swing arm,etc. You do have to remove the rear brakes, e-brake, etc.

the SIR tool does not pull the flanges (hubs). you have to do that either by pounding from behind, which i don't like to do, or with two long prybars from the outside. the tool does reinstall the flange though.

hey John,

Not to be contrary but I used the sir tool to pull my hubs. The bearing race came out with the the stub axle. i used a dremel to cut the race most of the way through. I then hit the cut with a screwdriver and hammer to break through the cut in the race the rest of the way. Maybe I'm talking about something different.

Well, can I add to this inquiry?
Anyway, I'm looking at my Porsche Parts and Tech ref. for the rear suspension and it has the following 3 parts...Axle bearing 999 053 020 01, inner bearing 999 059 047 00, outer bearing 999 059 056 00. I'm confused, which ones are the ones that "wear out" when rear bearings go bad? Is it all of them? I'm having a low rumble/whirring sound from the rear that is tied to speed. I need new tires badly (new ones on way from tire rack) so I'll find out if it's tire noise but am prepared for a bad bearing(s).

I had mine replaced on a 79 930 and it was $900 with a completed replacement of the halfshaft and inner and outer wheel bearings. And this was at a DEALER. It was in and out in two days and no hassle (okay...except for the $900).

88911 I would bet your noise is tires, lots less hassal than going in for the bearings. If tires don't do it then go deep. My replacement took about two weeks, but thats two to three hours a night and Saturdays about 6 hours, plus I built the tools to do it and source the $4.00 worth of scrap to make the tools out of.
