I just installed a new 12 bolt with 9" ends a month or so ago. No whining from mine. break in instructions were pretty specificThis past weekend I put an all new 12 bolt and I've noticed that it whines whenever I let off the throttle. It has at maximum 25 miles on it. Is this normal during the break in procedure or is this something to be concerned about?
Mine are Richmond 3.73s so maybe that's it. I didn't set up the gears, someone built the whole rear end for me so they might have messed it up. It would surprise me though, the guy has a good reputation.If the gears whine they may not be set up correctly, the pinion depth and backlash may not be correct, the gears should be quiet.I heard richmond gears may howl beacuse how they are cut, I have 4:11 richmond gears but mine are quiet though.
Give the guy at the gear shop a chance to check it out and make adjustments if necessary. He wants good recommendations from his customers.Mine are Richmond 3.73s so maybe that's it.

I would agree if they had more miles on them but considering they've only got a max of 25 miles on them it shouldn't be enough to set a permanent wear pattern yet. JMHO
Called the guy that set them up today and he said I need to break it in for 500-1000 miles.The guy I use for gear set-ups claims you cant always go by the book for quite running.
The Richmonds get a bad rap for being noisy but I've never had one make noise if set up correctly, not by the book.
If yours is noisy it needs to be reset.
