Rear end complete rebuild.

[SS_Sean]

Time to rebuild my 10 bolt this winter. I'd also like to replace my original posi with another limited slip. What is the best posi unit? Auburn? Eaton? Give me some ideas. I will probably also be going with some aftermarket axles. Who has good steel axles pre-cut for our rear ends? Who would you recommend for ring/pinion? What company has the good prices?

Any/all help is appreciated!!

I went with the eaton 30 spline carrier and moser axles. I also went with lpw cover and brace kit

Who'd you get your axles from, chopped?

Eaton is a better posi unit over Auburn

You can put fresh clutches in the stock posi for under $100 so unless you are going to bigger axles that is what I'd do. The eaton unit is just like the stocker, and that's what I went with in 30 spline. I don't think the base Auburn is rebuildable and I had 2 or 3 friends who wore them out in a few 10,000's of street miles. The Auburn Pro is rebuidable but the same $$ as the Eaton, so why bother?

moser. the rest came from Randys ring and pinion

Where did you get the rebuild kit for your stock posi? I've checked my local sources and came up with nothing...but then again I live in southernoregon....

More good info! Thanks guys....

I didn't buy the clutches I bought a whole new posi. www.gearsrus.com has them for $129, and I assume gm has them.

Must have been a while ago, as I dont see a posi that cheap anywhere on that link

 

[Dave]

That's for the clutch kit....... scroll down further you will see it

 

[SS_Sean]

Good info and good prices.

Here's a link to my Moser axle install thread (with pics) from last year. Have not had any leaks yet, but not too many miles either. Maybe 1000 miles or so tops, and at least 1 trip to the dragstrip running mid 10's. For the first time ever I was not worried about the rearend busting open....
