Transmission And Diff Question

[demons_wing]

hey guys..just a question from a nubbie...ive noticed over the last couple weeks that when im changing gears and release the clutch and press down on the accelerator, i can hear a clicking noise from the rear of the car..i have a 1990 Gts-T with about 88k...theres also a little seepage on the tranni too...im not sure whether the knocking is the tail shaft or the diff...should i replace all the oils with some synthetic and clean it up and see if i can spot anything?..or should i get it looked at??

If you're unsure, i'd get it looked at.

It wouldn't hurt to change your gearbox and diff fluids and check for bad seals/leaks.

The clicking noise you speak of, does it just happen once when you press the accelerator? Or does it continue to click, and increase or decrease with speed?

its not a continous click..just once when i press the accelerator..kinda like what youde hear if there was backlash in gears or the yoke..
