***UPDATE***
Ever since my truck was lowered, and I realized they had cranked the keys down as well, and I went to raise them back up some, the right side was always higher than the left. after putting in my new bumpstops, and, as mentioned, had them resting on the control arms, tonight, I took them out, trimmed them down, reinstalled them and I have even amount of space on each side now. I think the shop cut one shorter than the other. My front end feels great! I didn't feel that swaying like I was after installing the new bumpstops and riding on them. But I'll know better after a road trip tomorrow evening.
MY REAR END, I don't know what to do....like I said, going over speed bumps for example, it sounds like something is loose, or banging. And I'm pretty sure it's not bottoming out, I've felt that and it's different. and it's usually initially going over the bump, not coming down off it. It's almost like if you have something loose in the trunk and bounces around when you hit bumps. Does it with small potholes too. I've looked underneath but don't see anything odd, but will mess with it some more this weekend, but any ideas anyone has would be greatly appreciated.
