Drive Shaft Diagnosis for 2nd Gens

So for the past month I have been having weird squeaking coming from my drive line only in reverse. I would just wash my rear U joints and than grease them as best as I could and it would go away. Well, it came back today with slight popping in reverse & drive but this time it wouldn't go away so I ran my truck down to a shop nearby to get it checked out. They jacked the truck up and got the noises to repeat thankfully and they said that the noises were coming from every U joint and from the sound of it they all needed to be replaced. So thats where my truck is right now. But I would rather it be fixed and replaced than have them go out and have an even bigger problem like a torn up transmission tail. So if you guys start hearing squeaking that matches the revolution of the drive shaft spinning and even slight popping GO GET IT CHECKED OUT DON'T WAIT!

 

Yeah, my U joints were getting really bad. A lot of squeaking and vibes I didn't know about because they built up over time.

Got the replaced with u joints with grease fittings (because prerunners come with u joints with no zerks) and everything has been running smoothly ever since.

 

Ya I am looking forward to having the grease zerks
