locker for rear diff.

cobrakiller · 11-29-2005, 03:50 AM

i have 4 supras, 3 turbo and one n/a. two of the turbos are wrecked, so i took a turbo motor out and put it in the n/a body. The n/a has 4.3 gears with a posi, the other good turbo is 3.73 with a posi, but it slips, is there anywhere i could get just a rebuild kit for the posi? I know one of the wrecked turbo's has 3.73's, im not sure about the other one...never checked it.

The posi is supposed to slip so you can corner without ruining your tires. Make sure you have good lubricant in the rear end. I am not sure about this part, but I had a Jag that had limited slip and when the rear tires were up and you spun them they would both turn the same direction. I think the Supra's are that way too. If they spin opposite then there is no working posi or limited slip rear end, but I could be wrong about that. All I know is that after 190,000 miles, mine is still working and it does get used a few times.
