You need 2 people too check for loose splines in the hub some experience is required.I recommend pushing splined section inward and appling green loctite too splines liberily. Retourqe axel bolt too 37 FT. LBS..Then car must sit for 3 hours for Loctite to cure.T his is an actual factory repair which is not in writing.Let me now if this works there are some other areas too look at. experttech
