Steering rack problems on the 88 started with a bad bushing. It usually ended up making a clunk sound. This metal rack bushing was found in GT's prior to 203159, and coupes & Formulas prior to 203414. This metal bushing needs to be replaced with a plastic bushing part #26010668 ($12.00) along with 2 new Stainless clamps #7841287 ($7.00ea.) The rack has to come out, takes about 2 hours to do the job. Just did this on my 88 and it solved a noise and slight driveability problem. This fix was covered by TSB 88-3-9 from Pontiac. For some 88 owners, this may help.
