Re: 71 Buick 8.5

Hi Jim, I sent my diff in for the repair. I sent via ups yesterday but I forgot to include a note after I taped up the box. I also sent in the axles, I'd like you to take a look at the bearings. They seem a little loose? This is the rear I've been having axle endplay issues with, and the play seems ...

Re: 71 Buick 8.5

Well, it turns out I don't have an eaton. It's a cone style diff. Is there anything I can do to improve it? Can I put a mini spool in there?
Will pics help?
Thanks
Dan

Re: 71 Buick 8.5

One more question
When the clutches are worn, can I feel like it's slipping? Similar to a manual trans clutch going bad?
Thanks

Re: 71 Buick 8.5

Still slipped but I didn't go to the track, I parked it for fear of further damage So I'm in the market for clutches, do you carry them for this rear?

Re: BOP 8.5 axle endplay

Hi Jim Still having endplay issues. My unit has a used eaton posi in it. I've tried shimming the axle bearing races, but still have endplay. .020-.030ish on both sides. I've read that I can shim and or replace the clutches in the eaton posi to help with endplay. Does this only apply to c-clip axles?...

Re: BOP 8.5 axle endplay

Hi Jim, I'm still chasing down this endplay issue. I was wondering what the dimensions of the original style axle bearings are? Someone suggested that maybe a later model full size GM car with an 8.5 rear may have the correct size? I found a place online that has the bearing, but they are expensive ...
