I have an aluminum LS1 driveshaft, but the tranny yoke has spread and the u joint starts to move around and cause a noticeable vibration at 90 (w/3.73 gears). The driveshaft shop tried to shim it, but it only moved the vibration point up like 5 MPH. Would someone buy this, or just the shaft itself (it's been balanced about a million times)? And how much do you think I could get for it? I don't want to cheat someone, but if they have lower gears you would probably never go fast enough to notice.

I'm not selling it now, but I just want the info.

 

if you tell your story you'll get a good bit out of it on ebay, or here

 

Like, $50 maybe?
