I just had my old worn shocks replaced on my 91 s10 with 120,000, because the truck would bounce all over the road, and make poping noises and creak. Now it rides great, but still makes poping noise and shimmys on sharp turns. The mechanic said the upper control arm bushings are very worn and the centerlink has lots of play in it, but it would cost about $500 to fix it. Is it fine to drive it for another few months until I get my next work bonus, or are my wheels going to bust off or something?
