Changing gear oil in a Jeep Wrangler JK front differential

[@LizzKillian]

Thank you! I am about to tackle this myself tomorrow. This saving me some $$$

[@motormaniac1]

Thank you! Glad to could help! It’s pretty easy. Good luck!

Here's a tip: turn wheels right ~1/2 way before fill, makes a big diff - ur welcome 😉

[@motormaniac1]

Ahhhh, that is a good idea!! Thank you sir ☺️😎🍻

[@TheAvionicsncoic]

@@motormaniac1 Also, since I did the rear punkin first, was able to use emptied gear-oil jug for practice. Thx for the base vid tho - very helpful!

[@Daniel-tv9tb]

Awesome video. Is the rear the same way ?

[@motormaniac1]

John Smith the rear is just a tiny bit different. If you have a limited slip differential, you need to add the clutch pack additive like Posi-trac or something. If you don’t have an LSD, then the process is virtually the same.

[@Daniel-tv9tb]

@@motormaniac1 I so not have the LSD (Wrangler Sport) so should be simple to do both myself. Thanks for replying!

The only problem with not taking the cap off and cleaning the casing & gears with brake cleaner is that the new fluid will be contaminated once introduced.

[@motormaniac1]

A simple flush is fine, as long as you change the entire thing and completely clean it out every other cycle. So you’ll flush once, and the next change you’ll take it apart and completely clean it out.

[@kakskjshsj4934]

how do i check if it’s need to change?

[@motormaniac1]

No need to check, necessarily. You need to change it every 20,000 or so miles. If you do hard core off-roading, you need to change it sooner.

Hey bro how many bottles did you end up using? i have a 2010 JK thanks!

[@motormaniac1]

Johnny Alonso Depends on which differential you’re doing. I’d say about 2.5 for the front, 3 bottles for the rear!

[@johnnyalonso]

@@motormaniac1 right on. Thanks so much man. I'll do this on my tight tomorrow. Thanks for the reply 👍

[@motormaniac1]

Johnny Alonso Not a problem at all. I’m really glad that I could help!

Sorry I like Amsoil

[@Eltee127]

Looking pretty decent??? I dont think so bud!! U driving through too many lakes!

[@motormaniac1]

Nope. Normal wear and tear from part time on road and part time off-road. The only time you should worry is if there are chunks in your oil, or the substance is thick, and milky white. Grey and sparkly is normal for gear wear from harsh off-road and trailer towing. Given that I’ve seen them many times since, and I’m still on the same set of gears more than 2 years and 85,000 miles later, I’d say they’re alright. ☺️🍻

[@motormaniac1]

BUUUT, I’ll tell you what. I’m fixing to do a gear inspection this fall when I change the gear oil. I’ll put up a video if I find anything crazy. It’ll make a good video. 🙂

[@Eltee127]

Just did mines today! Not a whole lot of difference other than yours looks like there's water in it and mines had more viscosity to it!!

[@motormaniac1]

@@Eltee127 Yea, when you add all the glittery metal flakes from abuse and towing, it changes the viscosity, and makes it look very different. Also, I always drove about 20 minutes to get the oil nice and hot,

[@motormaniac1]

@@Eltee127 so it’ll flow into the catch pan better.
