i have a clunking noise coming from what sounds to be the rear of my truck. i can only really hear it when im slowing down going under 30 (i think thats partly cuz my exhuast). it does it really fast and then as i slow down the clunking gets slower and slower. my balance alignment and rotors are all good i just recently changed them. also, one morning i woke up and smelt like something was burning under my truck, it wasnt coolant i think it may have been tranny fluid? any suggestons?

 

oh sorry its a 5.4 2003 xlt fx4

 

clunking could be your u-joints. not sure about the burning smell though

 

i thought u joints right away, but then i did smell that burning smell and it really smells like tranny fluid but that clunk does sound like a tranny issue
