Vibration after new gear install?

[Gazingwa]

i had a different set of Yukons installed. The vibration went away about 95%. They were still somewhat noisy. Pattern looked good after a couple thousand miles. I ended up selling this jeep after all that. I believe Yukons are just not good nowadays. I would stick with Dana spicer in the future.

I have 4.56 Spicer gears and a driveline vibration which is why I’m asking. Thanks though.

Supposedly, Yukon's are now made in China and there has been problems with the gears, one issue is they start "powdering" after the install, which I could only think bad steel leading to premature wear,

One other thing is a lot of gear manufactures have changed there machining process and have stopped back cutting the ring gear, which then makes them very noisy, in the past 3-5 years there has been a big ordeal with gear manufactures and specialty set up companys that set up the gears and break them in kinda like dyno time and gear run in for mesh and backlash,

And I here its very common, so, with the wear will they now become noisy?

just what I have read, I got Dana/Spicer for mine, just have to do the install,
