    ok its a 2006 it has 143k on it i replaces the entire relay rod all the steering compents and it didnt help its a clunk when i punch the gas or if the hit a pot hole on the drivers side. the truck has 265s on the stocks wheels and i noticed it was tweeked all the way up with stock possible bad shocks it sounds like something is loose. I checked the calipers they have alittle wiggle but not loose the bal joints look good all the rubber bushings look ok i applied some grease to most of them i had the truck in a local shop but they couldnt even figure it out if i hit a pot hole on the passenger side no sound if i hit a big bump it bangs. it does sound like its coming from the front and definately the drivers side im so lost any ideas?

    not yet could they be cracked or loose and this may sound pretty idiotic but where are those mounts?

    Motor mounts are on each side of the block, below the exhaust manifolds. The transmission mount is on the cross member going under the tranny, from one frame rail to the other. The mount bolts to the cross member and to the bottom of the tranny. it is a rubber mount that can deteriorate and allow the tranny to shift around.
