Hey Scotty. First I'd like to say I like your no nonsense integrity in your videos.

Unfortunately I've been having problems with my 1995 S10 pickup with extended cab. It's got the manual transmission. It has the 2 piece drive shaft.

I've had a lot of problems with leakage at the transmission output. I've replaced the seal 3 times since I've owned it. This last time I noticed that the U joints needed replacement. I replaced them before so I figured no big deal. I was annoyed I only got around 20k miles out of them but I've read that S10's are notorious for U joints. Well I was doing it, I noticed the mid-baring rubber was starting to fail. so I replaced that too. I opted for the rounded 1 over the square this time cause the square one tends to have problems with the rubber tearing.

So I put it back together and realized I didn't mark it. Now I get a nasty vibration at around 50mph. I tried every combination I could come up with for the U joints. Trying to get it right. I even flipped the 2nd part of the drive shaft end over end. That seemed to help a little bit. But I still have the vibration. It did not do that before. I'm at my wits end. I contacted 2 drive shaft balancing places and they won't touch it because they are not factory U joints. They both told me to buy a new drive shaft.

It wasn't a problem before so why can't I put it back. I checked the u joints to make sure I had them in right. everything seems to be correct according to everything I have read.

Please help. Thanks.
