| have these mythical quiet sets of gears. Did they go in quiet? Or did they whine initially and die down after a few miles? A few hundred miles? The Richmond website says break-in is 20-30 miles tops. Mine were excessively loud. I drove two break-in cycles...24 miles. I used Richmond Gear Oil. I do have polyurethane rear diff bushings, but I can't believe these things could possibly transmit THAT much more noise than OEM rubber. Basically I need to be talked into putting this Leader Gear diff back in, otherwise I am sticking the OEM 3.69 back under there. I have to drive this car to Dallas to be shipped asap and I have no idea when I am going to get another chance to fool with it again. I am SO glad I chose to hedge my bets and install them into a 2nd diff.
 "The American people will never knowingly adopt socialism. But, under the name of "liberalism", they will adopt every principle of our socialist program, until one day America will be a socialist nation, without ever knowing how it happened.... I no longer need to run on the Socialist Party ticket because the Democrat Party has now adopted our platform." --Norman Thomas, 1944 Socialist Party Presidential Candidate "Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy, its inherent virtue is the equal sharing of misery." --Winston Churchill |
