Had the single driveshaft replacement installed about a month ago. Dealer did a wonderful job removing the carrier brg.

Just before a complete stop & when the brake pedal is released to start, the truck now has a noticeable double clunk. Narrowed it down to the drive train was not unwinding.

Pulled the shaft out & the spline was almost dry with a considerable amount of grey metallic residue. I cleaned out the female spline & smeared a VERY thin film of high-temp grease in the spline teeth & grooves.

Unbelievable difference. Truck runs so smooth & even rides softer on rough surfaces probably because the drive train can flex as it is supposed to. [img]smile.gif[/img] Problem is, the clunk is beginning to come back. Dealer says the driveshaft is supposed to be installed DRY. Go figure!

Anyone think the Transynd would help with it's superior lubricating properties over the Dextron III?
