How to make a Yukon warranty claim
- Contact NVMOS with your order number, the part, the vehicle and photos of the failure
- We open the claim with Yukon / RANDYS Worldwide, who investigate after notification
- Keep the failed parts; locker collateral claims require inspection of damaged parts and receipts for parts and labor
- If Yukon verifies a defect, it repairs or replaces the part; lifetime items get a no-questions-asked replacement on the first return

It is aimed at gear installs on lower-mileage axles, where you want everything for the pinion side in one box.
| Spec | Detail |
|---|---|
| Fitment | Toyota clamshell-design front differential, reverse rotation; Toyota 4Runner (2003-2020), FJ Cruiser (2007-2014), Tacoma (2005-2023) |

Order by differential and position, since several Yukon kits cover similar housings. If you are not sure which axle you have, ask us. Yukon install instructions: download the PDF. Not sure it fits your build? Call or text us at (920) 249-7744 with your year, trim and setup and we will confirm it.
What comes in the kit?
Timken bearings and races, a pinion seal and small parts for the install. Ring and pinion gears are sold separately.
Can I use this with the original carrier bearings?
Yes, that is the idea. It suits lower-mileage axles where the carrier bearings and races are in good shape; if they are worn, plan on a full overhaul kit instead.
Will it fit my vehicle?
It is made for the reverse-rotation clamshell-design Toyota front differential. Call or text us at (920) 249-7744 with your year, trim and setup and we'll confirm.
