    I am getting a lound bang when putting the TH350/203 in reverse so I changed a U-joint that had just a hint of slop.

    I didn't fix the problem so I'm thinking it is my drive shaft. The slip yoke and drive shaft can be moved up and down where they meet. I took it a part but I couldn't tell if the teeth on the drive shaft were worn or not and I couldn't see much on the yoke but there is a pretty good amount of movement.

    If that is my problem ,Is the drive shaft shot? How much for a new yoke and what would it cost to have the splines replaced on the driveshaft?

    Youve got to take the driveshaft apart at the weld and discard the whole slip joint and buy a bew slip joint and reweld it to the tube.Not sure on the price to have it done but i was quated 150.00 for just the yoke and slip shaft....

    Wholy crap that is a lot. I' check around here and see what prices I can get on a rebuild along with having a driveline shop look at it.

    Thanks.

    Is your shaft stock? You might be able to just go to a junkyard and find a driveshaft with the yoke still on it for cheap.

    The first thing that comes to mind is the ring and pinion. I have gotten the noise you described from my truck before I changed the rear end. It was wore out and there was alot of slop in the gears, so you would get this noise when putting the truck into gear. Just a thought, it might be something else you want to check out.

    Thanks for the compliment. The truck is a little more beat up now. I managed to scratch the passenger side 4 days after I finished it.

    I do have a stock drive shaft. Looking in a junk yard is a good idea. Thanks.
