Thread: Opinions on posi in a T?

Tweet

Looks like I may have a bad pinion bearing in the S10 rear thats going under my T.

It's a peg leg diff now, but I have a posi unit out of a Camaro 7.5. It's the right series for my 3.73 gears and the spline count is right(28), so it should install OK. Now would be a good time, since I have to tear it down anyhow.

I'm wondering about how such a light, relatively high HP car will drive with a posi rear? I know my straight line will be better, but what about going around corners? I'm worried about understeer(push) in curves or getting squirrely in sharp turns. I know it will be a handful in the wet.

Anybody have any opinions or info to share?

Thanks

This is the posi unit I have.

Guess I should add that this is an Auburn cone type limited slip unit and not a solid posi.

A car as light as a T with the skinny fronts and wide rears that the type usually have, will be a squirrely beast if you get on the gas in a turn. Like someone said, paint it green with yellow wheels, 'cause it's gonna plow like a John Deere!

Amen.

Skinny fronts, posi's, and light cars are all good by themselves...But when you combine the 3 it can be a handful!!!!!

Another consideration would be one of the electrically controlled posi-trac units... Shut if off when cruizin', turn it on to drag race..... Seems it would be the best of both worlds for a lightweight T running big & littles....
