Can’t wait to roll around under this on the 30 degree ground trying to replace that crank sensor.
Fun fact: both of my cars are from the same year!

That’s way more clean than I’d have expected. Makes it almost worth freezing your butt off today.

It is super clean. Just needs a good wash, really. I have a propane space heater that's gonna be pointed under the car the whole time lol.

Oh, that will be a great bad weather beater

And you got the best 4wd system . Very nice.

Nice! I’ve always had a soft spot for the WJ .

Eh, locking diffs would have been useful to me

Sooo nice

I don’t believe those came stock on any GCs, did they?

I’m going to say no.

Quadra drive got gerotor diffs front and rear that can fully lock as well as the viscous coupling in the transfer case is full time 4 high

From my reading those gerotor diffs are limited slip, not fully locking.

Do yourself a favor, check the wiring harness at the back for the valve cover and make sure it’s not rubbing. I just had all kinds of electrical issues with my mom’s WJ because the harness rubs against a stud back there and actually wore down to bare wire on a few. That might be where your O2 sensor issues are coming from. Apparently electrical issues from that area of the wiring harness are pretty common.

Quadradrive on Overland models. It works well but requires wheel spin to work.

Well kind of. They are open until a wheel slips and starts pumping fluid to compress the clutch pack. Given enough wheel speed difference they can lock but you will get some forward movement before that so they may never truly lock . They kind of act like a clutch based lsd but they are speed based not torque based and there is no preload on the clutch pack so lifting a wheel may actually help you depending on the situation.
A clutch based limited slip relie s on torque to drive the spider gears apart and into the clutch packs. If you lift a wheel there is no torque so the preload (or springs) drive the spider gears into the clutches.
On a side note The viscous coupling in the transfer case cannot lock. There is a separate mechanism for that when you
shift into 4hi part time. This coupling
also relies on a speed differential between the front and rear driveshafts to work.
On another side note the wk (2005-2010) and wk2 (2011-current)
could
also be had with the same system but it had solenoids. These solenoids didn not lock the diffs like some believed but would release the fluid build up to unlock the diff when
abs or stability control was active.

I’ll pretend I understood any of that in order to say: nice breakdown!

Not manual lockers, but they could be had with LSDs capable of fully locking.
