Re: Tightening up the limited slip?

You can rebuild it, but it wasn't very good from the factory. If you want a good limited slip, spring for an aftermarket.

Re: Tightening up the limited slip?

I heard this weekend that the Sterling had a decent setup but people complained about the noise so they took out some of the clutches and put metal shims in so it would slip.

True?

Fix?

Re: Tightening up the limited slip?

some people over do the friction modifier and almost completely disable the effects of the limitied slip. A cheap easy way to start would be to change the fluid and start by not adding any friction modifier, then only add it if it binds up too much when turning.

Re: Tightening up the limited slip?

Dieselmaster was thinking exactly what I thought.... start over with the fluid. my limited slip works perfect, I put 2 perfect divots in my drive way just yesterday backing up. much cheaper than new rear end ($1200.00 + )~Aaron

Re: Tightening up the limited slip?

Add xtra clutch packs just turns less before lock up worked on the 8.8 in my mustang but same concept buy the rebuild clutch pack kit and save a couple of your old ones to put in as shims.
I could get you more specifics from my diff guy tomorrow if you want more info

Re: Tightening up the limited slip?

This tech article was written by a good friend of mine and has worked for countless 8.8's. Page 3 has the general idea of restacking the frictions and steels.

Re: Tightening up the limited slip?

Would that apply for the Sterlind as well? I would think so, otherwise you wouldn't post it right?

Re: Tightening up the limited slip?

I *think* so. We are going to try something out here in the near future on another friends truck.

Re: Tightening up the limited slip?

Keeping an eye on this b.c I've got one wheel peel and I just want it to do both in the next few months before going to a detroit trutrac.

Re: Tightening up the limited slip?

Diff guy says don't try this unless you know what you are doing.He says when you buy the dealership rebuild kit it comes with different sized shims. the shims will be the last disk you take out of the carrier (closest to the brakes on each side) He says install the biggest shim in the kit for the fastest action (it may chatter through corners)
you've been warned but it helps a ton you make the call

Re: Tightening up the limited slip?

How much are the rebuild kits? And where's the best place to get one?
