No noises
No humming. Work great, excellent kit and materials. You will need tools. But this has all the parts and shims required for front and rear non Rubicon axles.

Love my Yukon gears!
Went to Yukon for a gearing package for my JKU. I wanted larger tires, but didn’t want to lose power when I went to the taller tires. This was the perfect solution! Stock gears were 3:21 and the 285/70/17’s were just too much for them. I went to a 4:56 with plans to go from the 285’s up to 315’s. All parts were very well packaged and the shop said everything went together as it should. No issues! ... show more

Great product
Great product, it was a learning process to install as I installed the gears myself. If your not mechanically inclined do not try it yourself. No issues at all and have stood up to some serious wheeling so far.

Complete kit
Everything you need, went from 3.21 to 4.56. Now I’m able to use all gears. Running 35” tires with 6 speed manual. Performance is now back to original factory feel, which I’m very happy with.

Bought these gears in August 2021, had them installed into my jeep JKU with 35" tires in October 2021. Here we are in march 2023 and the pinion gear broke. Vehicle is mainly a pavement princess, rarely even driven on grassy parking lots..... Called Yukon and discovered they only have a 12 month warranty on them by default unless you buy their Y.E.S. extension within 30 days of buying the gears for the lifetime warranty..... I didn't even know about the Y.E.S. programs as I ordered them off Amazon. Very disappointed as I thought I had bought a quality product..... I am now reading reviews out there with similar problems..... Stay away from this brand.... the attached pictures are of the exploded pinion gear after 15 months and 7500 miles of blacktop driving, never in mud once... Cheap steel most likeley or horrible heat treating ... show more
