I was in accident it damaged the rear portion of my car. According to my mechanic, they needed to repair the trailing arm, upper and rear arm suspension and compensator arm. The mechanic also advised me to save money that they will send it to a fabrication shop the existing trailing arm instead of buying a new one. After it was fixed I have noticed that the wheel is not aligned properly. I immediately brought it to camber alignment but according to the mechanic, the camber cannot be adjusted to its recommended measurements. My car is not alignment and I keep hearing a humming sound (like an airplane) on the repaired portion. Thank you in advance for your advise.
