I don't think I would put more then just a little STP in the rear end. Rear end lube is specially designed for Hypoid gears which require extreme pressure lubes. Use a GL -5 gear lube. I don't think it will cut down on noise anyhow. I have tried different lubs to fight gear whine & none have been sucsesful.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
