Alright. I hate to do this, but I got regeared at a reputable shop here in SoCal and have this very noticeable whine when on the coast side coming to a stop, or just letting off the gas. It was also accompanied by a pretty significant pinion seal leak as I was doing my ~20 mile break in + cool down cycles. Once I noticed this I took it back to the shop first thing the next morning and noted the noise and the leak. They replaced the pinion seal on the spot but said the noise is a "driver comfort" thing and to let him know if it got any louder in the future and maybe we can get the gear manufacturer to warranty. He also noted that the sound likely would not go away with break in, and that it's not of concern because the drive side is set up right and the noise is only on the coast side. He also said that gearing is louder the bigger the ratio, but I only have 4.88s and have heard plenty of jeeps regeared much higher and have never heard a noise like this - it's audible for pedestrians and I get looks. My front axle is not making noise, it's a brand new Ultimate Dana 44 that came 4.88 from the factory and has no front axle disconnect. No noise from the front in 2H or the brief moments of 4H I've tried. The noise is primarily in the 43mph and under area. I haven't gone over 50mph to say for sure what it may sound like because I'm not broken in yet, but it seems like it quiets down quite a bit coasting faster than 45mph.
I hate to have to try and argue this out and don't want to put anyone on blast here, but I cannot find a single point after doing research that says noise is normal or expected after a regear, and that whining is indicative of incorrect mesh or preload.
In y'all's experience, is there ANY situation where this is normal? An aggressive drive side setup? A certain brand of gears?
I have 260 miles on the break in so far.
