Squeaking in rear end of 99

[slichic69]

I have 1999 tacoma extended cab, 5 sp man trans with 4x4. When pulling away in 1st, 2nd and 3rd gear there is a squeaking noise from the rear of the truck. You only hear it when your on the gas pedal. I tried greasing the drive shaft but that didn't help. I would appreciate any suggestions.

I think your driveshaft has a center support bearing. The bearing may be worn. I don't know a good method for checking it other than removing the driveshaft assembly and checking that the bearing turns smooth and free without any rough spots or binding. The bearing isn't servicable but it can be replaced.
