When i start driving from a dead stop i hear a clunk coming from right about under my feet and it only last for the first 10 - 15 mph then goes away what could it be

 

Ive got the same
been looking over it tons and havnt found anything.

 

Axle shaft ujoints. I had this same issue, replaced mine this past weekend and no more clunk. You might also make sure the trackbar mounts are snug on the frame side, but mine ended up being the axle ujoints.

 

Agree, it is front axle shaft u-joints. I too just had the same problem.

 

yeah i just got off phone with local mechanic said the same thing i will get them tomorow and replace then i hope it is cause it does have little play and sounds like its coming from that area and everything else is tight

 

Grab the front drive shaft and move it while watching the u-joints.

 

like what kind of motion back and forth or side to side

 

Greasing the splines on the rear drive shaft where it slides over the out-put shaft in the T-Case can also remove a common clunk problem.
