Does this look like normal up and down play in my tailshaft. Side to side is the same. Seems excessive to me. it's a 4l80 to a 2 piece driveshaft on a 2wd ecsb Silverado

Thats alot of play.

The u-joints look shiney and new though, are they the correct size or have any grease in them??

 

Mine doesn't have anywhere near that much play. Are there grooves in the yoke when you slide it out? I would get a bushing and put it in the tail housing just to be on the safe side. It is an easy job to do too.

 

All that's less than 6 months old. Jakes stage 4 and a custom Driveshaft Specialist out of Texas driveshaft. I didn't install any of it so I'm not sure if it was sloppy from the get go or not. I've been noticing a little vibration that felt like maybe a u joint was going out, and that's what I found. I spent too much money to be having these problems already!

 

Is your suspension considerably different than stock? I think universal joints need a certain amount of angle applied when rotating to keep the needle bearings healthy?

Pulling a shaft is pretty damn easy. I'd do that, make sure the yoke isn't damaged and also inspect the needle bearings. Careful though.

 

I didn't feel any play in the u-joints. I contacted the shop that did the work and they are looking into it for me. I don't plan on being the one who fixes it considering I didn't order or install any of that stuff myself and it's all only about 6 months old.
