When I am taking off from a stop and disengaging my clutch there is sometimes a clunk before it actually goes in gear.....Its like my truck starts moving and then it slips clunks and starts to move again. Is this my U-joint or tranny slipping??????
slip yoke probly most ujoints make noises under motion like under power. but i wouldnt doupt your u-joints are dieing being your lift and tire chioce probly a good idea to replace them anyways under maintness
