TracyB1970 Posted November 15, 2022 Share Posted November 15, 2022 Not sure if this is the right place to ask this question. I have a 70, if I go over a hard bump I hear a thud. It’s almost like something is bottoming out in the rear. Increasing air in the shocks doesn’t change anything, any suggestions? could it be that it needs Body Bushings replaced? How hard are they to replace? Quote Link to comment Share on other sites More sharing options...
Dtret Posted November 15, 2022 Share Posted November 15, 2022 In reality the bushings aren’t that bad. The problem is the bolts that have the cage nuts Quote Link to comment Share on other sites More sharing options...
Scott S. Posted November 15, 2022 Share Posted November 15, 2022 Thud or a clunk ?? How good are your air shocks and rear springs ? Might just be the differential or control arms hitting the exhaust. I wound up switching to gas shocks and re routing the pipes because of a similar issue after I installed a 12 bolt. So it could just be something simple. ; Quote Link to comment Share on other sites More sharing options...

It looks like you got the best year in the First Gen grouping and with Blue being the best color you have chosen wisely on color. I could be wrong but that looks like Astro Blue. rob It’s more of a thud like something bottoming out. I’m going to check everything Quote Link to comment Share on other sites More sharing options...

MC1of80 Posted November 15, 2022 Share Posted November 15, 2022 Get rid of the air shocks. 1 Quote Link to comment Share on other sites More sharing options...
cny first gen 71 Posted November 15, 2022 Share Posted November 15, 2022 The air shocks on mine make noise if the air leaks down. 1 Quote Link to comment Share on other sites More sharing options...
cny first gen 71 Posted November 16, 2022 Share Posted November 16, 2022 I guess I should add that I only put enough air in them to keep them from making noise because the ride height is where I want it. Air shocks will coming off one of these days. 1 Quote Link to comment Share on other sites More sharing options...
TheBMan Posted November 27, 2022 Share Posted November 27, 2022 I would check shock bushings, sway bar bushings, control arm bushings, and make sure your exhaust is snugged into position and not banging against anything. I once had the same problem - thud over bumps. I replaced everything before realizing that the wheels had the wrong backspacing and the sidewall was hitting the quarter panel lip when the car dipped enough. I swore it was a suspension problem but nope, putting the correct wheels on the car solved the problem. 1 Quote Link to comment Share on other sites More sharing options...
