I have a '93 fullsize Blazer and I just got done replacing all the front steering components (idler, tierods, pitman and all four shocks). I also had the front end aligned. Before I did the work the front end was crazy loose. Now, the front end is nice and tight and it drives down the road great except at highway speeds the whole truck sways from side to side when you hit bumps. It is pretty bad on major bump and causes you to slow down to bring the truck back under control. The front has a sway bar but not on the rear. I was wondering if anyone has the same problem or knows if A rear sway bar will fix it?
