I have put up with this problem for a while now but it is getting on my nerves. My truck shakes pretty bad whenever I come to a stop every so often. Anybody know what it is?

My truck also makes a really loud creeking sound when coming to a stop. Almost like an er ere err errrrr. I seems like it comes from my leaf springs or something when I push the truck forward when it's stopped. My bottom leaves are misalligned- could that have anything to do with it?

Anybody know how to remedy these situations? Thanks.
