Yeah, Brett, go out and get some pics of the underside of your front driver's side suspension components and whatever damage the curb or anything that day caused. These guys on here are really sharp when it comes to these trucks and they'll be able to pick out almost anything out of the ordinary.
oh ya i know there awesome here. i dunno cause 2wd works fine no shimmy or shake even at 80 lol i tested it. but when i lock 4 in it kinda pulls to the right. only when i give it gas. im thinking the spare tire has a lot more tread on it so maybe that could be the cause the pull but i dont know what the clunk is.. i guess ill take it in to a 4x4 shop. or something. it only clunks when i take it out of 4 and drive a bit then bang it feels like 4x4 popped out from the right side and is now in 2

If you think it is the spare that is causing it, rotate the tires, front to back, and see if the problem resolves or moves. If it doesn't, you got problems. I would still lean toward getting an expert to look at it ASAP. You don't know what damage you might be doing to it by driving on it. Could be racking up the $$$ without knowing it.
