hey-Hey!!!,
My 1990 behaved just as you describe. It is combination of grabby clutch and spring wind up. It was worst with low engine rpm and attempted gentle clutch engagement like you'd wish to do when in a parking spot. I replaced the clutch with a stock Luk 05-101 from the 245 hp HO motor( along with a HO flywheel and starter spacer ). This behaviour went away. I can still feel the springs wind up( traction bars would be *VERY* useful ), but the spring wrap/clutch engagement chatter resonance is history.
cheers,
Douglas

Hey folks... So I have a relatively new issue... When you start out from a stoplight or when I'm starting to back into a parking spot my truck will start to hop... It's the worst when backing up but pretty pronounced any time... Stop lights or initial movement... When the clutch is being used to get rolling. I was initially thinking the clutch might be contaminated somehow but i was reading abortion worn out springs...
Anyway any insight or advice would be truly appreciated.. It's really staring to bother me.
Also, I do have a full air ride system, but I tried under-inflating, over-inflating, and standard inflation and it didn't make any difference.

I went through the exact same thing. It majorly sucks @$$. I had a new nv3500 put in my z-71, new sachs OE clutch just like you, flywheel resurfaced. It was great for about 2000 miles and then the lurching started on a trip 800 miles from the shop. Best way I found to work around it was to almost pop the clutch and back in right away just to get the truck rolling a little, then take off riding the clutch a little more than normal. Lots of fun with a trailer on a hill at a red light.
Took it back to the shop when I got home and it turned out to be the brand new pressure plate had cracked in 2 spots. The mechanic and the manager at O'reilys were unphased as if this is a common issue. O'reilys paid the labor on the fix as well as the new clutch kit. Still going strong today. It never did it again.
