my 88 feels a lot looser in turns / changing lanes etc then I think it should, like ill start to turn then it feels like it just wants to start turning more(backend feels like it just wants to 'keep going')... I checked all bushings / bearings, they seem to be good, the car just received new tires not long ago, and an alignment, and ive checked tirepressure in all 4 corners, anything else I should be looking for?

Check the torque on the long bolt for the lateral links. It likes to come loose and then allows the rear wheels to toe in/out under throttle/braking. If thats good, check the torque on the short bolts on the lateral links as well.

Depending on sidewall stiffness of the tires as well as the profile height, it is possible to feel the rear of the car moving side to side as the sidewalls flex.

I know it can be a number of things but I always like to point this one out also when I hear of this happening on an 88.

I've had a couple of vehicles, including 1 Fiero react that way and it ended up being a ball joint or rear tie rod end. In a turn they would suddenly try to oversteer.

Check your tranny mounts, if they're broken the car would sway when changing lanes

+1

The mounts can look perfect and be ripped. You will need to jack up the engine a little bit to see the break.

Tony_C and hookedonspeed, I concede. I have an 88, but have never had the need to go under the rear end, though I purchased a full set of Dickman ball joints for it. They've never been installed. I mis-read the link I posted above.

If you got the car aligned recently, like in the last 6 months, take it back and have them check it. These cars are very twitchy if the toe (front and/or rear) is not right.

Before you do anything else, just tighten the long bolt. Mine used to change lanes just by me getting on or off the gas. That was the fix.

You say the bushings "look" good but they are 25 years old. They could still be worn, deformed, cracked, or dried out. I know this is a bit different but this is the dog bone I replaced because the bushings weren't CENTERED in it. When I got it out, look what I found. This is from my garage kept 62K mile automatic GT.



This damage was not visible at all while installed. Maybe you should lean on Rodney to finish up his 88 bushings kit.

I saw another post mentioning loose cradle bolts having the same effect...may as well check them at the same time


Edit: sorry...guess this was an old thread...probably already resolved by now...

Yeah Id say cradle bolts, or maybe worn out old struts.

While you're at it, make sure the axle nut is torqued down. After being R&R'ed a few times can start to loosen up over time.

The most likely cause is that the bolt attaching the lateral links to the knuckle is loose.

Also check the trailing link bolts.

Finally, alignment settings, cradle bolts, and wheel bearings.

I recently got tired of the sloppy feeling in my 88's rear end and an odd knocking noise that was getting worse and worse under acceleration. Turns out the cradle and suspension link bolts had all come loose to some extent and the knocking was b/c the passenger side rear cradle bold which had backed out 5/8". under accel, the cradle would knock up against the rear frame rails. After tightening all the suspension and cradle bolts there was much less slop, but the car will now turn slightly to the left when I mash the pedal. I think this remaining problem is being caused by worn out rear struts.
