Rear end is LOUD.
Hello everyone, I've had my 2010 GT since new and it's been a great car but it's aging a bit. I've started to replace a few components here and there to keep her running well. Well, recently the rear control arms were replaced as the stock ones were clinging to life by a thread. I used the cheap SR performance control arms from American muscle which have poly bushings (at least I think its poly). The car is riding GREAT how ever the rear end is so loud it's almost unbearable. I know that "up grading" control arms make the rear end louder but good god. Is it safe to assume the rear end is going out as well? I have 4.10 gears in it but over all I haven't been to hard on this car at all, I've maybe dumped the clutch at around 2k rpm maybe 5-6 times in its life. It's not making any unusual noise, no clunking, it cruises fine, but I do notice that if I change lanes to the right the sound almost completely disappears. It also seems to drive nice and strong so really other than being very loud it seems okay.
I wanted to get some opinions here before I go to a shop and they charge me 200$ just to open and inspect my rear end.
