what gears you gonna run it with?

 

what are lockers and what do they do?

 

Probably just the stock ones because I am for sure going to go bigger in about 2 years. It's hard to decide on tire size and gears when you know that you will end up driving across the country in another year or two.

 

well... ill jump in on this one.

Stock vehicles are mostly "open" differential or " "one tire fire" .. a locker will make both wheels turn at the same time all the time. really good for mud, rock crawling, pretty much anything. if you get one of the wheels off the ground then the other wheel on the ground will still have power to it.
pretty simple.

 

Auto lockers allow the tires to turn at different rates on turns......when no power is being applied to the axle but you are right that they both turn when under power.

 

i'm gonna have to invest in some. i want to climb Mt. Everest with my jeep

 

Why do you have to replace the carrier when installing an Aussie? You may have to do that with a factory limited slip in the rear but up front you shouldn't have to get a new carrier - when changing gears yes - the carrier break is 3.73 and up so if you cross that line (either direction) you'll need a new carrier or at least thick cut gears when going from 3.07 to 3.73 and up.

And I know we're talking about a rear 8.25 but here's a quick write up I did for a front D30 in a TJ...I believe if you have 3.55's or lower gears you won't need to remove the carrier - only the PS bearing cap.



**********
The short version...

Remove tires (3/4")
Remove calipers (2 - 1/2" bolts per side)

Remove diff cover (10 1/2" bolts)
Remove passenger side bearing cap (2 5/8" bolts - make sure you put it back on the same way!)
Remove roll pin and cross shaft (3/16" drift pin with straight shaft)
Remove side gears and pinion mate gears (keep track of side gear shims)
Install Aussie (refer to instructions)
Re-install bearing cap (5/8" - 45 Ft. Lbs.)
Re-install axles (make sure the axle guide is still on - 3 12pt bolts each side - 75 Ft. Lbs.)
Re-install calipers (2 1/2" bolts per side - 11 Ft. Lbs.)
Re-install tires (5 3/4" lug nuts per side - 95 Ft. Lbs.)
Put diff cover back on and fill with oil (10 1/2" bolts 30 Ft. Lbs. - Gear Oil - 1.2 L (2.5 pts.) of 80W-90)
Go wheelin' !

The tools you'll need...
Jack
Jack stands
3/4" socket - or whatever you use to remove the tires
12pt 13mm socket (calipers, axle hub assembly and diff cover bolts)
3/8" ratchet and extensions (for the above listed items)
zip ties (to tie up the calipers)
5/8" socket (bearing cap)
1/2" drive ratchet with a 3" extension (to remove the bearing caps)
3/16" drift pin (to remove the roll pin)
ball peen hammer
gasket sealant (and something to scrape the old gasket off!)

Small flat head screwdriver (to put the Aussie springs in)
Torque wrench

I think that's everything...
