my XJ has 67,000 miles on it and i got its with 64,500 miles on it and idk what maintenance the previous owner did on the jeep. Do I need to change the fluid??
Thanks!

 

Personally, i would do it just for piece of mind. That's what i did with almost every fluid when i bought my Jeep.

 

its better to just change all the fluids so you know that it was done. peace of mind is better than wonderingif you should. for the cost of fluids and filters i just change everything.

 

I agree did just that when I bought my 48K mile Jeep just to be sure, rear axle oil black front axle clean never been used!!

Things ar emore likely to go worng if you don't stick to the servicing intervals all for the sake of $50 of oil!(all oils being changed)

The reason I change diff fluids in all my new jeeps is the stock vent location isn't high enuf. A stock jeep is capable enuf and can water in the vent when it gets stuck. So I change the fluid and raise the vent inside the cargo area. Then I never change it agean. Probably should though.

 

i change mine in the spring, then again in the fall. unless i go through some deep water, then i'll change it once i get back from wheeling.

 

I only check mine after deep water, so far, no water makes it into the axle I was kinda expecting it to tho

 

Every 15K for diffs and transfer case, or after submerging in water.
30K for transmission, power steering, coolant.

 

That's why I run my vents up so many changes of fluid add up. Its quick and eazy. But I should change it seasonally and that's good advice since changing weather can cause moisture.

 

what type of fluid do i need to use? rear is Chrysler 8.25 sorry ive never change dif fluid before lol and is there a certain type of seal that i need when i am putting it back on?? or any tools that i need other than a wrench and rubber hammer?

 

What you need is a razor, some liquid gasket. I beleive either a 8, 10, or 12 mm a screw driver (preferably a wood chissle.) The chissle is to break the prevous seal by slowly prying. take it easy as to not bend the diff cover. Use the razor to scrape clean the mating surfaces for new seal. clean it with paper towel. I dont know your proper oil, but mine was like 100-120. got it at the local auto store.

 

i change it when i get water in the dif

 

I also take brake cleaner and flush out the housing. Be shure to check for shavings and ab normal wear. I also use a wire wheel on a drill to prep for the seal. But a razor works just takes longer.

 

I'm doing the same thing with my new-to-me cherokee. I did find a felpro gasket for $5 or so for the rear, rtv only for the front dif. After searching this forum and jeepforum.com, I decided on the Royal Purple gear lube. So far, no leaks, no noise.

 

Depends on how often you submerge the axles.
