ARB O-Ring Replacement
One day on the trail I hit my front locker and my compressor just ran and ran. I new I had an air leak, but I wasn't sure where it was. I did the normal thing and popped my hood and hear air coming up from the radiator, but that didn't make sense because there isn't an air line there. After some more digging we realized it was coming from my axle housing vent tube. That can mean one of two possible problems. The air line has come loose in the housing or an O-ring has failed.
ARB lockers work great, but even they have a weakness. Its a small O-ring that costs no more than a couple of bucks. The only problem with replacing the O-ring is you have to literally take your ARB locker out of the axle housing which means you guess it. Everything must come out/off. Wheels, calipers, rotors and axle shafts. Its not really a difficult task, but just time consuming.
Servicing your Diffs
Simple maintenance is very important on your Jeep. Sure you can pay somebody to do it for you, but after a while all you have done is paid somebody to do something that you could of learned how to do yourself and done many times for the same price you paid to have done once. For example below I serviced the front and rear of my wife's XJ for approximately 12 dollars and the local Jiffy Lube wanted $29 per axle. 2x29=$58. At that cost I could change front and rear again and again nearly 5 times. Most auto parts stores will accept the old lube because they know you might buy something else while your there. I normally buy a soda on the way out.
Super30 and Super35
For the longest time I wanted to lift the TJ and throw some 33's under the fenders. Why that size? That's another complete topic all together. However I knew the magic number for twisting the rear axles was 35-inch tires and well I didn't want anything bigger than 33's so I figured I was somewhat safe.
After the install of my lift and tires I came to the conclusion that stock gears simply are not cutting it. I went out a time or two and even made a long distance trip down to Baker City Oregon to hookup with the Kanyon Krawlers in Virtue Flats. The wheeling was great however running in 4lo, 3rd gear sometimes to keep up with the rest of the pack was horrid, but hey you have to do what you have to do.
I decided to upgrade my gears to 4.56's and was seriously considering locking the front with an aussie locker so I could at least have a locked front end. We had a little bit of Tax money coming this year and the wife said "Get some quote's on a regear and that locker you wanted."
One of the most common questions asked by new jeep owners is, “Why isn’t my 4wd working?” Though there are several possible reasons why the 4wd system of the jeep may be malfunctioning, the most common answer lies in the vacuum disconnect system that these models use. To understand why, you first need to understand how this system works
Adjusting your pinion angle
When you lift your Jeep at least three or more inches (or install a raised tcase skid plate like I did), you will want to consider a way to adjust your rear axle pinion angle. When it comes down to adjusting the rear pinion angle, you have two choices:
ARB Locker Wiring Without ARB Pump
I used the ARB wiring harness to control the ARB air selenoid so that I could easily add a rear locker and ARB pump as a back up system later. There are some tricks to this as the ARB system is designed so that it works like this. The pump must be turned on 1st, then the rear locker actuated before the front can be actuated. The ARB directions do not make much sense if your not using ALL of the components. This write up will help explain how to get it to work.

Aussie Locker Dana 30 Front Axle
Just about everyone and their mother knows that a Jeep, right out of the box is one of the most capable (if not the very best) off road vehicle on the planet. Now, what if I told you that you could take a stock Jeep, throw about $250 at it and make it perform a hell of a lot better on the trail... would you be interested? Well, with an Aussie Locker by Torq Masters installed in your front Dana 30 axle, a hell of a lot better is exactly what you will get. The Aussie Locker is strong, amazingly quite, easy to install and will take you places you never dreamed your Jeep could go.
Aussie Locker install
One of the most useful additions to any trail rig is a locking differential. I had originally planned to put a LockRight locker into Project No-Bucks. As I was about to order, I came across a new locker being offered by Torqmasters, called the Aussie Locker. It appears to be identical to the LockRight, but is supposedly stronger and with less backlash, and for $40 - $60 less money. Assuming this thing works as well as it's supposed to, look for another one of these in the front axle as funds become available.
Aussie locker into the front axle of a jeep
...is a great idea! Seriously, installing an aussie locker into my dana 30 front axle took a little more work than I thought, but was well worth it.
Setting up the axle’s ring and pinion gears – it’s one of those jobs that even the most experienced 4x4 builders approach with hesitation. There’s probably no other job performed on a 4x4 that carries more mystique than how to set up gears. Why does the job have the reputation it has? Does it deserve it? Can even the first-timer get decent results at home? The answers, in order, are: “You’ll understand by the end of this article”, “sort of”, and “Yep, you sure can.”
Change your differential fluid
This write-up describes the basics of changing your Jeep's differential fluid, whatever model it might be. I took photos as I worked on my Dana 30, however a Dana 44, Dana 35c axles, etc are all similar.
This isn't difficult and it's certainly not beyond the capabilities of most people. If you can change your oil, then changing your diff fluid is easily within reach.
This write-up is meant as a basic how-to article. Obviously, if you've swapped axles in your Jeep and you're running something other than stock, you probably know how to change your diff fluid. For everybody else, here goes.
Converting your YJ Dana 30 to TJ shafts
If you have a pre '95 YJ, odd are you are running the tiny 260x ujoints. One way to run the larger 297/760x ujoints is to swap in TJ D30 shafts into your axle!
Dana 30 Axle Seal Replacement
The left front axle on my '95 YJ had been leaking gear oil out the tube and onto the lower inner knuckle every time I drove it for the last several months. Later on, it was bad enough that it would run down the inner tire sidewall and leave a puddle on the ground when I parked on an off-camber spot. If gear oil can get out, then water & mud can also get in, which means bad things for the gears in the pumpkin. Here's a few pointers on changing the axle seal.
Dana 30 to Warn's Hub Conversion Kit
After making the hard decision to build my Dana 30 rather than go through an expensive axle upgrade, I decided to purchase an ARB and the Warn Hub Conversion kit. I began the project by removing the front axle housing from my Jeep. This isn't necessary to install the Warn Hub Conversion kit, but I wanted to take the entire unit to my friend Jess's house to take advantage of his expertise and vast tool selection.
I drained the gear oil and proceeded to remove the hub/bearing units and the axle shafts. Then I removed the gears/carrier/ez-locker, making sure that the carrier bearing caps were marked so I could put them back on the same way they came off. Jess came by with his truck and we drove the housing to his garage where I spent some time cleaning it up. Jess wanted to do the ARB first, so we did that install. Once that was done, we began the hub conversion kit. Along with the hub kit, I also bought Warn's premium axle shafts, including the one piece shaft on the passenger
Dana 30 Wheel Bearing Replacement
I don't know how long wheel bearings are supposed to last, but after 140K miles and larger tires, I am sure it is time to inspect them. Well, that is not so easy on a Jeep Cherokee's Dana 30 front axle. The front wheel bearings are incorporated into a one piece hub assembly which takes special tools to take apart. For most of us, this hub assembly is a non-serviceable part. I took the easy way out and purchased a new hub assembly from the local auto parts store.
Follow along as I show you easy it is to replace the wheel bearing assembly on a D30 front axle.
Dana 30 with ARB Air Locker
I had been considering swapping out my Dana 30 and Dana 35c axles for some time. I really wanted to find a set of Dana 44's or maybe a Dana 44 for the front and a Ford 9" for the rear. However, the Pro-Comp Coil Conversion Suspension kit that I have did not offer any axle options other than the stock YJ Dana 30 and 35c. In fact, now that the kit has been out for almost a year, they still don't offer any other choice, and according to their tech department (at least at the time of this writing - May 2000), they aren't going to offer any other choice. So, I decided if I want to have a stronger front end, I was going to have to bite the bullet and upgrade my Dana 30. I had already replaced 2 of the non-serviceable hub/bearing units on it, and I wasn't really happy with the Detroit EZ-Locker when it came to tight turns on the trail. So I decided to put an ARB in there (already have one in the rear) and get the Warn Hub Conversion kit.
