I am back driving my car around and hereing alot of clunks and noises as I turn and move around, I now something is not right, so I get home lift the rear to find both rear wheels with endplay about 3/8 of an inch , I now thats bad news but how bad im not sure , not sure if anything has been done to the rear end, It goes in on tuesday for inspection but was wondering if there is any input from you guys here, I was also noticing vibrations at 70 miles an hour, I do not believe its the front tires out of balance but maybe the drive shaft out of balance , the rear end has 331 gears and also has 10 inch rims with a 396 somewhat pumped up. Thoughts ??
