The car: 1988 Supra Non Turbo, AT, LSD rear end
Problems: AT not functioning properly Needs U-Joints
Replaced the LSD gear oil Friday with Mobil 1 synthetic gear lube 75W90
Shift into reverse, and then shift into 1st, and the rear of the car shakes.
Stop at a stop sign or traffic light, take a left or right turn. 1/3 of the way into the turn the rear starts shaking.
Stop at a light or stop sign, and take off going straight. No problem.
It feels like the Limited Slip is trying to kick in going around corners. It is heavily pronounced in 1st gear, less so or non-existent in 2nd gear and not at all while at cruising speed in Drive. Sometimes the rear of the car shakes badly.
I'm replacing the u-joints Friday, but I have a feeling something else is going on as well. Also, some other suspects: the suspension needs to be redone: I have new springs, it needs shocks. The bushings look OK for a car this old (they look good, period)
This car has an Independent Rear Suspension (IRS) so it has CV type drive shafts; boots look OK. When we get it on the lift I'm going to give the rear end a good going over, and also check for loose body/suspension bolts.
