shutter on take off
Over the weekend i took the driveline off and greased the slip yoke, it was clunking pretty bad starting and stopping. Now its smooth as glass other than i can feel a slight shutter or rumble right as i start accelerating from a stop that i didn't notice before. Lasts just a second or two and then its gone and no problems at all after that intitial start. Any Ideas?

Do you have any sort of lift or leveling kit on the truck? It sounds like the driveline may be out of alignment just a touch. This is pretty common when the rear of the truck is raised. The fix is to use shims to realign, but don't ask me how to do it because I need to do it also and don't know how.

That should only show up at speed (drive line speed.) Did you inspect your U-joints? Recently I was performing some maintenance on the rear end, and while the drive shaft was out, I just popped one of the caps off to take a look. What do ya know, ONE of the needle bearings was broken and 1/2 of it was missing. "Spun" fine, no binding or anything, but dead lined. New U-joint, and now the truck rides "smoother" hard to explain, but the joint was transmitting some vibration through the drive line that I had not attributed to drive line problems.

just last year. Used the Redline Synthetic brand of gear oil, and i believe that has the LS additive in it. I never noticed it before, just after i greased the slip yoke

If for some reason you do need to shim the driveline, crawl under the truck and there's a support where the 2 piece driveshaft joins. 2 bolts, an 1/8 in pice of steel or two and you're good to go.

this may be a sucky reply, but here goes anyway...pull the diff cover and check the teeth, there may be one broke in there, and maybe that broken piece of metal is floating around in the fluid, and at start off, it starts working it's way through the rest of the teeth...i dunno...
maybe hit the usual suspects before you do this...also, while you're in the rear end, check the side to side "lash" of the punkin'...there's shims in there too that could work themselves out over time, or wear out...

Any advice on where to get the 1/8 in pieces of steel? I need to do this bad.

A piece of flat stock that you drill will work on this Bob. Any hardware store should have it if there are no steel supply places around you.
