I think I know my problem, buy I need y'all to give me some confirmation. I have a 97 GT that I bought 2 months ago. It has 54,000 miles. After going underneath, it seems like everything is still stock. (when I bought it off the 50-something, no offense, year old guy, it still had the snorkel in the airbox). Anyway, under hard acceleration in 1st 2nd and sometimes 3rd, I have a creaking in the rear end. Do I need to replace the bushings in the upper and lower control arms? Do I need new upper and lower control arms? Do I need new shocks? Or ALL OF THE ABOVE? Any help would be appreciated.
