Weird jerk at stop and go

[sweet addiction]

Thanks, I will look at it this week.

you have to pull the shaft and grease the splines to the intermediate shaft. 20min job at best

Thanks for the tip!! greased the splines and it was smooth all the way home. Now the lower back support of my seat broke. WTF!! Always something. It looks simple I need to stop at the GM dealer and see if there is a part.

I work at a GM dealer. The post above mine is correct. Driveshaft splines are binding due to lack of grease. I had the same issue with my personal truck. Grease the driveshaft yoke real good and it should stop. Jeff Wurl

I took care of that jerk at the stop and go.

From the title of the thread..it does sound like you met some freak of nature while getting your turbodog and slushie....

fix the wire in the seat this week. It just broke off. Just rolled up the upholstery and there it was no problem. I about have a new truck, just needs a new paint job.
