I have read the threads and they all point to bad universal or u joint. It is a 95 with no u joints it is just universals held on with pillar blocks. I put the truck in neutral and twisted the drive shaft each way. There was no play in the drive shaft, but the was some play where the axle (pumpkin) meets the drive shaft. Is there supposed to be play in that spot? The transmission works flawlessly otherwise. The only problem is when i put it into reverse it slams into gear.
