08 wrangler JKU stick shift had 3.21 factory on 35s worked well but no acceleration. I can feel the torque across all the gears I am shifting into 3rd at 20~ mph now but I’ll be able to maintain highway speeds easier instead of hunting gears. Would pair better with 37s to bring down the rpm’s just a lil

Q: Whats included Dakota5 years ago
Hi, just wondering if this includes the main axle seals and bearings at the wheels, Can't tell from the info. Thanks!
- 0 of 0 people found the following answer helpful
  A: If you are talking about the rear axle bearings and seals, then no, it does not. None of the install kits do. The front only has inner axle seals(in the diff) and those are included.

Q: Regearing aaron6 years ago
Do i need anything else other than what is in this kit?
- 3 of 3 people found the following answer helpful
  A: You will need gear oil, and if your Jeep has 3.21's from the factory, you will also need a new carrier for the front axle. It can be found here: https://www.northridge4x4.com/part/differential-carriers/2010999-dana-spicer-30-jeep-jk-wrangler-empty-open-differential-case
