New gears making noise on coast

[Panthers65]

Great skill to have I've never learned that. I can do a ton of wrenching myself but gears never was something I got into.

There's honestly nothing that's so complicated that the average person couldn't understand, it's more so the average wrencher isn't use to working with calipers and adjusting things to the hundredth or thousandth of an inch. and it really sucks knowing you've got a half hour of pulling things back apart to make an adjustment that small. I'm an old fart now, I did the set in my gladiator on a set of quickjacks, and I'll never do that again. It's either a two post lift, or pay someone else to do it.

We had a bunch of scrap parts laying around the shop, the guy that taught me grabbed a toyota 3rd member and had this bracket he welded together where he could bolt the 3rd to the bracket and clamp it to his work bench. Had a pivot point where you could flip the 3rd member upside down and back. I bought a bottle of the marking compound and he had me add and remove shims and mess with the backlash and run a pattern every time to show me how moving the shims changed the pattern and messed with the preload. Once you get the concept finding the specs and getting the gears in spec isn't hard.

I called a shop a month ago about gear sets and they got pissed when I said I didn't want nothing to do with Yukon.
Yukon has got that stuff in alot of Gear shops.

yukon was the gold standard 20 years ago, apparently they had big issues during covid and their quality tanked. I haven't had a set in the last 5 years so I don't know if it's recovered, but that's a hard reputation to overcome.

Doing any now it'd be spicer or nothing. about 10 years ago Spicer went to machining all their gears with a 0 depth vs factory, so in theory if you pull your factory pinion out and it's got a 0 on it, and your new set has a 0 on it, you can straight replace the gears without any shim adjustment on the pinion and it'll run a perfect pattern. The sets still come with marking compound for you to check, but my front and rear were both dead nuts on

Yeah and Yukon tells the shop to eat shit when warranty time comes around. A buddy of mine was a vendor/installer and he told Yukon to eat a dick.

So had a talk with the shop today and they definitely know it’s the rear making the noise. He ordered a set of spicers for it so that will be done by Wednesday. He does have pictures because he is pretty perplexed and frustrated with Yukon.

Yeah got an even better one for ya , so I called another shop and although I believe them to be a reputable place . From PA they do Jeeps all the time their rates were high. The Revolution gear sets came to 1102.00 but adding labor and oil it came to 3790.00 I was like Holy Moly this is gonna cost me an arm and a leg. I am in WV so anyone that can direct me to a place less expensive that is reputable let me know please.

My Yukons are junk, I have a howl on decel, I have just lived with it for two years, need to get off my ass and put another set in

Well shop called and said after the spicers it’s perfectly quite and the shimming was more in line with what they expected. So just install spicers and be done the first time

I have spicers and I have a slight whine at coasting from the front diff. I don’t think it’s the brand but more so the shop that installs it. It’s not loud enough for me to care and only happens at 50mph when I let off the gas. ¯\_(ツ)_/¯

Just picked up the jeep and can’t hear anything at any speed. Happy to have my jeep back and the shop take care of me.
