silverado makes sound during takeoff

[mikemac]

when i take off from a stop, my truck makes a sqeeklike noise from the rearend. i don't know it's the rear end or a u-joint. anyone have this happen? it's a 99 silverado ext cab.

it is the slip yoke, remove rear drive shaft and lube the spline on yoke with a thick silcone grease, or high temp grease, do lube spline on the transmission output shaft.

just replaced my u joints at 70,000 miles on my 2500 hd, mine was doing the same thing.. there was no play but they were bone dry inside the caps because the stock ones dont have grease fittings
