Clunking Drivetrain Part II

[stingray427]

I had an AOD installed and ever since then, I am getting a significant clunking sound on shifting, expecially from first to second gears. oddly enough, this has gotten slightly better over time.

I am also now getting a whine in the transfer case that is muted by holding the levers. This has recently turned into a clunking sound of the levers and general area every time I let off the gas. Does this sound like the drive line is out of alignment or something is loose or...?

My trans guy checked the driveshaft and everthing seems tight but he did mention that it was possible that when he installed everything, that my Bronco might have been on a lift for part of the install and then on the ground for some of it.

Any ideas as to what is causing this?

Thanks.

Come on, nobody has an answer for this? I find that hard to believe with all of the genuis on this forum.

put it up on jackstands and try to find the noise that way. look for loose or out of balance parts. ck bushings and mounts. check your u-joints first. now that i think about it, it probally is a u-joint. good luck
