Re: Drivetrain noise and vibration solved.
Before I answer your question, I had an issue driving back from work last night. It seemed like the drive train was binding during acceleration. I put the truck on jack stands this morning and checked out the new drive shaft and everything was looked fine. I lubed the front and rear universal joints and extension shaft. After changing the oil, I took the truck for a test drive and it ran fine and smooth. I floored it twice just to see if i could repeat the issue I had earlier, and it didn't come back. I am still very happy with the drive shaft, but a little concerned that something else might be wrong.
If you want to talk, just send me a private message.
