Jerry , thanks for that post on back lash. After experimenting with different ratios I finally decided on the one I should use . I had it in the truck in the past for a while with only minor gear noise . Before reinstalling it I took it to a rear end guy to go over it at which point he adjusted the lash and anything else that might be adjusted in it .
I installed it happily thinking this would be my last pumpkin change . WRONG . This thing screams big time but only on acceleration , the harder I press on the gas the louder it screams. The rear end guy suggests the pinion bearings might need tightening but this hasn't been attempted yet.
Jerry whats your thoughts, can this be corrected or should I search out another 4:57 rear for a HO 72.
Thanks John .
