I don't know a thing about rearends but have to ask, do the detroit locker rearends make loud clicks when turning like leaving a parking lot and going out on the street?
There have been a lot of leftover Detroit Lockers showing-up on the market from racing teams. If used as-is, these units are often very aggressive, and make a lot of noise. They are much noisier than the common soft lockers sold at places like Summit, and do not have the small buffer springs on the cross shaft to make them quieter. Then again, it could be set up wrong or an old worn-out unit... LOLSure sounded jingly jangly when he left the parking lot that's for sure. Don't think i've ever heard one before and i'm sure there were plenty out there but maybe they didn't or weren't as noisey as this one.
