    Frequency of gear oil change

    This question is to those who have years of experience actually using their Jeep for what it is for. How often do you change gear/axle oil? I have just under 10K on JLUR and was considering doing it now. I have off-roaded probably about 12 days in total since I bought it in December. All of this off-roading including rock crawling and steep rocky inclines.

    I try and do mine every 12-15k no matter what. It's cheap insurance.

    so, If I am towing or offroading alot I do every 15K, normal driving every25 to 30k. I may be wrong though. I do have 200k on my Jeep though.

    I end up doing a number of water crossing a year, so just as a pro cautionary measure, I change it after a long wet run like Drummond.

    I go every 15k or after any trips that involve water crossings.

    75-140 here but I’m running 5.13’s. Just taking a guess you’re running stock gearing so whatever the manual recommends for you. Likely 75-90.

    I changed mine at 9k miles or so, to 75-140 in rear and 75-90 in front. I was stock rims and tires then, but I've always put 75-140 in my previous trucks and since I routinely hit 90 on highway, so likely a good fit. Since moving to 37's, I most definitely will stay with 75-140.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
