Replaced the one in my 70C10 and loved it. I lost count of how many rubber 'bushings' I had to replace for the 3 piece.

Re: Center drive shaft bearing or one piece drive shaft??

When I bought my truck, PO had a one piece drive shaft in it. After I installed a new motor/transmission with the correct motor mounts, the existing driveshaft didn't seem to fit (too short). I ended up having another one piece made by a driveshaft shop. The guy was pretty knowledgeable and said that the driveshaft that I had (brought it in with me) was too small in diameter, and would have definitely caused vibration when driving at higher speeds. The new one is much bigger in diameter and I won't know of issues until I finally get it back on the road.

I think you will find people in this forum that will argue both ways concerning the merits of a one piece vs 2 piece drive shaft.

Talking Re: Center drive shaft bearing or one piece drive shaft??

I had 2 piece for many years and had no major problems. I had the 6.0 installed and they cut the 2 piece to short. So they had a 1 piece installed at no cost to me. I have no problem with it and I have a LWB truck.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.

Did a one-piece with my LQ4/4L80e in my LWB. No vibration or noise. Happy with it. I say go for it.

A good drive shaft shop will ask your max engine rpm and length then determine shaft diameter. Mine is 3.5" diameter.
