I don't know what's going on here man. You said in your first post that your aux fan isn't working. Why don't you work on fixing the thing you know is broken? You confirmed that when you raise the RPMs, thereby increasing airflow through the radiator, that the coolant temps drop. I don't know...

Yeah, like maybe a $15 dial indicator gauge and a bench vise! If you want to get real fancy, add an inch-pound torque wrench. IMO, the real bitch with setting up gears is not tooling, but the assembly time to do it right. However, if you are a good Jeeper, then you will enjoy the entire job...

Yes, bolt together. No, not noisy. Tighten the bolts and it will not budge (assuming you mount it properly to your roof).

Tgregg, I have observed in my '90 that when in D, the tranny will freewheel when the throttle is 0%. I.E., coasting @ 40mph in D, RPMs will be at ~900 if I am off the gas. However, if I shift to 3, or 1-2, then there will be compression braking when coasting and the engine speed will match...

Another ballpark guess - my old '89 XJ did something similar to yours, and I was pretty confident it was related to 210,000 mile-old motor/tranny mounts. It never seemed to do it in 1st gear, but in reverse I would get a groaning/pulsing feeling when backing up hills. It may be due to the...

The speed sensor will tell the AW4 "hey... we're at 45mph here", in conjunction with the TPS saying "and on light throttle" so the TCU will deduce that you should be in 3rd+lockup (or somewhere around there, in power mode). A bad speed sensor may lead the TCU to think "5-10mph" (really, "0mph"...

My understanding of the power switch is that it is just that - a 12v switch. So that really points all fingers towards the TCU. An inspection of the wiring connections and the harness would be in order!

Don't know if it is the same part at all, but on my '90 there is a lever on the side of the seatback that, when lifted, allows the upper half of the seatback to pivot... Definitely feel a difference in the lower back.

Don't the front wheels engage using vacuum-powered collars? What if one of the collars was malf, and only one of your front wheels was driving? That would explain a pull to one side.

I thought I would find this in a search, but no luck. I'm gettting some odd behavior from the AW4 - it seems to jump in and out of lockup (and sometimes hunts between 3rd and 4th gear) when cruising @ 35-45MPH. I'm convinced it is associated with the throttle pedal position. I think it's a bad...

Overhead console We've all spent some time on this question and it reminded me that I hadn't posted pictures about my CB job yet. My '90 XJ came with one of those overhead consoles. In front there is the temperature gauge and compass. In the back of the console is a garage door opener slot and...
