Critical Rear/Front Axle Maintenance

[libertybob]

Was just at the Jeep dealership and the service manager commented that Liberty's are one tough vehicle. He said he services several with 250k to 300k miles with original engines and trans and still going strong. The only weak spot he said is the rear axle if the owner runs them low of oil. He said to keep the oil at the proper level and the rear ends never fail either. So, check your axle oil level! My owners manual says oil level should be 1/2" below the fill plug level. To check mine I made a guage. I took a coat hanger, cut off a 8" length of wire, bent it 90 degrees, and scribed a mark at 1/2" and 1" from the 90 degree bend with a triangular file. Insert the wire in the axle and see the level of oil in your axle. Simple to do but critical per the Jeep dealer.

Finger works quick and easy as well
Stick it in, pull it back out, look it over, wipe it on your old sweatshirt and done :icon_lol:
But yes proper fluid changes and amounts are important in any differential be it front or rear

That's how I do it. Even the old sweatshirt part. :gr_grin:

Almost every week, check oil, coolant, brake fluid, diffs, Tcase and ******. I guess I need a hobby (or maybe I have one and didn't know it...) :emotions34:

Gosh I love the smell of gear lube..=eek...
I have to add or you may have to...
There are open diffs and a limited slip rear axle.
If your Jeep came with the trac-lok rear diff, when you change the gear lube you must also add a limited slip (or posi-traction) additive.

I have 10 or 12 bottles of that and no use for it. Got them in a deal and just keep moving them around
