I recently had a lot of work done on my car. 97 Chevy Cavalier. The bill was very large. I took the car in because the breaks were squealing and needed work. The whole carriage seemed to groan and squeak whenever it hit a bump of any kind and I wanted that looked at too. I also pointed out that there was a new, higher motor “hum” while the car was in neutral (and accelerating) While there, they found several other things wrong. They said the sound of the engine was normal acceleration sounds. I approved the work. Now, a few weeks later, the carriage is still groaning and there are some new and frightening squeals when I turn the car. I’m thinking that I may have been charged for work that they didn’t do. Should I take the car back to the place that did the work? Should I take it to another place? What should I do if I find out that the original shop was negligent in their work, or if they charged me for work the did not do. All advice will be greatly appreciated.

How do I install a new actuator rod/lever assembly? My actuator lever broke, and I can't figure out how to manipulate the new assembly between the tilt assembly and the casting. Thank you!
