This is not a recent problem. I was the service, parts, and body shop director for a GM dealership in 1997. We had lot of vibration problems with the new Chevy trucks, especially heavier duty 4 wheel drive pickups. GM technical support did not have a workable solution but suggested we try to fix the problems by changing out shocks, tires, rear suspension components, etc. Every truck was different but generally we had the best luck with better quality tires and shocks. The worst vibrations did occur in the 60-65 mph range which seems to be some kind of harmonic balance problem with the complete drive system. GM never seemed too concerned with tweeking the frame and suspension components even though it was a statistically significant issue brought up at every regional meeting. We even had buyers who returned their new truck and bought back their trade-ins. Our mechanics spent a lot of time riding in the truck bed trying to figure out what was going on. GM lost a lot of customers in our area to Fords. We had the same GM issue with the "clunking" drive shaft on our pickups and Suburbans. We knew that issue was caused by the drive shaft catching on the splines when brake torqueing/binding caused it not to slide on the splines and then it would release and hit transmission input shaft. If you kept it lubed up with a good grease it would stop the "clunking" for a period of time. We also put "super balls" in the drive shaft coupling to dampen the impact but that was only an intermittent solution. Hard to believe the 65 mph vibration is still a problem after 20 years. We kept an expensive set of Michelin's tire sets at the dealership to put on the "vibrating" p/u's before we started wasting a lot of time trying to figure out a workable solution.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
