I have this clanking noise when my rear end hits a bump. I think its the same noise as the front and i replaced the front shocks but i still have something making a really annoying noise out back.. I spent over an hour with a hammer under my truck to figure out what it was but i had no luck... ANY IDEAS???? to be safe im going to buy new shocks anyways cuz they are the stock ones and need to be replaced but could it be anything else? Thanks for the help!!!
