I will be replacing my 3.73 gears and installing 4.56 gears in my 9.25 AAM front axle and in my 11.5 AAM rear axle.

I had a few questions for anyone who has done this swap:

First, did you have any problems taking anything apart(ie. removing pinion yoke etc.) or putting it back together?

Second, did the pinion depth come out correctly with the factory pinion shim?

Third, how many tries did it take before you achieved an acceptable pattern?

Lastly, any tips that you may have?

Thank you in advance.

 

the yoke is a verry tight press fit onto the pinion shaft

best tip i have is verifying if your getting 2 step or 5 step gears, patterns and setup specs are totaly diferent.

if the guy your getting them from doesnt know, then buy some where else or make sure you can tell .....

 

What size tires are you running to warrant 4.56?
