New to forum. I have a Sierra 99 1500 great truck. When I hit bumps in the road it really sounds and feels rough I think it's maybe just a shock issue but was wondering if there is any bushings or springs that could cause this. I've never replaced the shocks and honestly never had a rough ride until now l don't haul any loads or tow with it. Any comments or information wold be helpfull. Thannks very much.
