    I used set-up bearings and it worked out great…I don’t know why they get such a bad rap. There must a financial loss for someone over it. At a bare minimum it can get you very close where you only have to remove the pinion bearing once or twice vs multiple times.

    The problem is...he didn't even use new bearings or even measure on the same spot on the race. With my set-up bearing, its a brand new bearing just like the one I was going to use for real.

    Well, in the end there's never a problem as long as you check the pattern again after final reassembly, but then the fun can start all over again. Have set up many rear ends, never used set up bearings or set up tools, never busted a bearing. In 99 of 100 cases you have the old shim out the rear end which gets you there for 80%. The last 20 is easy when using the right tools.

    Many of us who only do this once or twice can’t justify the $300 bearing puller tool. The bearings make it quicker and easier for the novice.

    No need to get fancy. A simple bearing separator is all I use. You'll need a way to pull the bearing anyway if the pattern is off on final assembly. Not trying to convert anyone to a new religion, just warning.
