I have been having this groan sound coming from the rearend sometimes when i turn sharp. well i didn't think anything of it cause the next turn it went away. i have a 5 speed with factory gears and everything too. today it turned into a parking lot then the spot and bolth time it groaned and moaned and started making this poping sound. my buddy said his did that same symptoms before his rearend went out. he didn't say if it was the limited slip thing or what. i'm thinking of getting a KB supercharger and upgrading the rearend anyway to 31 spliners and i'm not sure what rearend unit i want to use. i was told that auburns aren't very good. anyway if anyone knows what is actually wrong with the rearend and comments on what would be some good axles and limited slip piece to install. thanks in advance
