I obsessively have 6 volvos, all pre-1984 200's, 3 of which are on the road. Three of these cars share a suspension fault; when driving around a corner and hitting frost heaves the rear of the car hops nastily. One of the three has new rear shocks, and my mechanic suggested that perhaps the shocks were dampped incorrectly for a volvo, so i bought some boge turbo gas rear shocks from ipd and put 'em on another car, and it still hops too! Could it be front shocks? Bushings? Am I just unlucky that ALL my 84's have this problem, or do others with 84 volvos see the same thing? Thanks for help!
