Front end vibration

I took my truck down some trails this past weekend but it was nothing serious. Just dirt trails going down a gas line and ever since then ive noticed a little bit of vibration around 50mph. Ive been hearing a rattling noise when I hit a bump but I didnt think much about it, because a while back, that bracket that is on the caliper came loose. I guess the pin worked its way out and cause it to tick a little bit. I popped the wheel off and fixed it, no rattling. So I dont think that noise has anything to do with it just thought I would throw that in there. Anyways, I was wondering if it could just be my alignment or maybe a weight balance issue on the rim. Seems like this would be a common problem for those that do some trailing. Is this an easy fix for someone that is decent with tools or should I take it somewhere?

Thanks in advance

 

could have knocked a weight off...im sure you may have checked that...and a little mud on the inside of the wheel will def throw your balance of to a noticeable vibration!! keep em clean and make sure nothing came loose! could be ball joints!

 

Im gonna take a close look at them tomorrow. I really hope it isnt ball joints. Ive heard they are a pain to replace.

 

I took my tire off just a few minutes ago and found that the bushing on my lower control arm is gone. Can anyone give me an idea on what its gonna take to fix it? Or should I just take it to a shop? If so, about how much would the repair be?

 

Which bushing? The LCA has 2 bushings on the frame side and a balljoint on the tire side.

Can you take a pic of the bushing in question?
