Chevy 'crump' update

[rustred]

Took Chevy 2009 Suburban to long-time trusted front-end shop. They jacked it up & did all the front-end recommended tests & found nothing wrong! We double checked but all is good, much to my relief but they had never heard of the complaint that it would shift or 'crump' ( my expression of the feeling) before. Long experienced driver here so I'm not mistaken but it's apparently not serious. Maybe its designed to do that?

why would you not take the service manager for a ride and show him what it does.

We recently had a car in the shop that would make a crunching noise that you could hear coming from the left front, and could also feel in the floorboards. The car was the same as new, only a couple hundred miles on it. It turned out that there was a stray nut wedged between the lower control arm and subframe. It wasn't visible during a visual inspection, but since we were sure the noise was from that corner, we unbolted the lower control arm and the nut fell out. The nut appeared to be an upper strut mounting nut and was probably there from the factory. I've found things like bolts and nuts or rocks that got flung up into suspension parts and make noise when the suspension would move.

Crump there has got to be a better word.

Look up

Chevrolet TSB #PIT5403E​

Folks do all kinds of crazy things to level them out. I am still not satisfied a suspension component is not worn out.

And one 2 was not aware of

#PIT3009M:​

HUH; I applied for a service manager position once and was told they wanted a salesman, not a mechanic

I’ve worked on some of years trucks and SUV’s with a creaking noise on acceleration and braking. Turned out to be the crossmember bolts for the transmission or the crossmember one under oil pan will loosen up slightly and start making noise. Have them check and make sure they are good and tight.
