Hi Jim Thank you so much for the work you did on my rear. The posi is nice and tight and the axles have the proper end play, finally!!! I took it out for a romp tonight and it's working great. Thanks for all the help and as always great phone service Keep up the great work!!! Thanks Dan IMG_0237.JPG...

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 ...

Hi Jim
I'd like to send my diff in for the repair
What do you need from me? And what do I need to do to send it in, reference number or something?
Thank you
Dan

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

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

Thanks for reply, Jim I changed the fluid, valvoline 80/140 convential. 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? I saw video from Randy's where he eliminated the springs and added shims to m...

Hi Jim I have a Buick 8.5 rear with an Easton posi. The clutches are worn and it's a one wheel peel now. Theres a car show at English town raceway park on Sunday the 1/8 mile is open and I want to make some passes. Can I change the fluid and NOT add the GM additive to make the clutches grab a little...

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?...

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 ...

Hi jim, We spoke on the phone yesterday about axle endplay on a 71-72 gm 8.5. Mine is a buick unit going into a 66 cutlass. My concern was the endplay. The drivers side was .020 and the pass side was .040. I did a little reading on the web yesterday and there not much info out there about endplay in...

Hi jim, i too am swapping an 8.5 into a 66 a-body. Mine is an olds cutlass. Ive read somewhere that the spring pads are different for the 71-72 rears than whats used on the 66's? Also, whats to torque spec for the axle retaining hardware, the bolts that hold the axle retaining bolts? And should the ...
