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."
2 low conversion with Vacuum Diagram
Intro. This page contains a description of how I used the Quarterback transfer-case low range selector switch from an early 80's FSJ (Full Size Jeep) Waggoneer to manually control the vacuum source that operates the Dana 30 front axle disconnect in my XJ.

4WD Vacuum Engagement Problems
This information applies only to stock Dana 30 front axle disconnect of the 87-95 YJ jeep models.
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:
1. Degree Cam Bolts.
2. Adjustable Rear Upper Control Arms
ARB air locker install
How the ARB Air Locker functions:
The ARB Air Locker is an air operated, driver controlled differential lock activated by pushing a dash-mounted button.
When the dash mounted button is pushed, compressed air, delivered by the ARB 12 volt, on-board air compressor is passed via a 12 volt solenoid down an air line into the differential housing. The air travels into the differential center via a specially designed seal housing which seals against an extended bearing spigot.
Via air galleries, the compressed air enters the piston chamber and actuates the piston and clutch gear, moving the gear into the locked position. The clutch gear now locks the side gear to the differential housing instantly stopping any differential action. The diff is now 100% locked, and both axles will deliver 100% traction.

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.
