JUST FITTED EVO 6 DIFF TO EVO4 ALL WENT OK THE AYC HAS BEEN BLED AND ALL FLUID LEVELS ARE CORRECT!
WHEN GOING OVER 60 MPH THERE IS BAD VIBRATION AND NOISE FROM DIFF WHICH GETS WORSE AS SPEED INCREASES.MY DRIVE SHAFTS,WHEEL BEARINGS,TYRES ARE ALL GOOD.
I HAVE BEEN TOLD THE DIFF WAS RUNNING FINE IN DONAR CAR.
ANY IDEAS? ANYONE HAD THIS PROBLEM?MY LOCAL DEALER IS NOT MUCH HELP
CHEERS

hi i am assuming everything else is ok,i would check propshaft and hardy spicers,try rotating prop one bolt hole at a time where it bolts on to diff and check out, maybe out of balance,hope this helps. :coolsm: :coolsm: :coolsm: :coolsm: :coolsm:
