I was wondering if siera gears are any good?
I have siera 4.56 in the rear and dana in the front.
At about 70 mph i hear a rumbling noise (not violent) in the rear and kind of a humming sound. not smooth sounding.
But when i take it back down to 65 the noise goes away for the most part.
I just had these installed by a rear end shop. So i did take precautions in breaking them in. Very light driving and not long trips. Dont want to get ring burn.
I paid $$$ good money for them.
Is this normal?
What should i do?
