Toyota Repair: drive train, rear yoke, slip yoke

Question
2003 toyota tacoma,,11.918 miles. 4wd , v 6, 5 speed. when i put trunk in gear forward and reverse and release clutch there is a loud clunk. its been to dealer 3 times for this problem.they say its not u joints,and cannot find anything abnormal,but they admit to hearing the noise..their answer, of all things to hear is keep driving it,i have a long warranty!!yes i made a complaint to toyota headquarters..

Answer

Take it back to the dealer and tell them to lube the slip yoke on the driveshaft, there is not enough grease in there and allows the driveshaft splines to make contact with the rear yoke of the u-joint internally, the grease cushions this and if they pump enough grease in it the noise will go away.
