Thanks Guys for all the replies,
I would like commend gmtech1 he was right it was in fact my axle support bushings i went to about 5 Garages and none of them could tell me what was going on so because 4 out of 5 shops said shocks went ahead and changed them which turned out not the problem the 5th shop i ordered him to drop the axle for inspection as he did as per my request we found out that it had lots of play that couldn't be seen when left in so today i went back and changed both sides to save money down the road at a cost of $460 Canadian... 2 bushings Gm most of the money was labor of course..lol..
