Service 4wd

[Ted392]

I run this fan mounted to my frame just in front of the pump. You have to reverse the power and ground wire to make it a pusher fan. Works well, I’m on my 3rd power steering pump so I knew I had to do something. I have the Apex kit with cooler running my pump at 1800 psi.

Curious as to how you mounted this fan to the frame.

I purchased an L-Bracket from Home Depot. I used one of the existing holes in the frame. The second hole I drilled out and used a self-tapping metal screw. I mounted the fan to the bracket with one bolt through the bottom of the fan into the bracket. Then I used JB Weld to fill in around the bracket and fan. This was just a quick bracket to see if the fan would keep it cool. I thought I would upgrade the bracket if it worked. I just did hole in the rock about a month ago and logged over 100 miles in 4-low and the fan never came loose from the bracket. I also never had the power steering hot light. I probably need to build a better bracket but this one it is holding up great so far.

I've had the Service 4WD a couple of times. Everything binds up and then after it sets overnight it is fine the next day. I've also had the clutches get hot and the front wheels quit pulling. I have added the FAD motor to the front axle so that when it binds up I can Disengage the FAD with a toggle switch and force 2WD with the Tazer. I also have an Atlas transfer case on order as I have had it with the full time transfer case and the problems associated with it.

I've had this issue too. I addressed it with the dealer and had it at their service center twice for this issue. 392 spent a total of 6 weeks at the dealer for this issue. Recently the 4wd light went on again and the wheels locked up. Same here.....light goes off and everything works properly when the Jeep is shut off and reset. I don't want to keep going back for the same issue. It seems that it could be some computer glitch that resets when the Jeep is shut off and the computer is reset. Frustrating for sure.

The clutches on the AWD T-case lock up. I went through two T-cases in 7K miles. Front clutch burned up both times just pulling in and out of parking spots at full left of steering wheel (no problems on the rocks/trails). I've had Atlas for a while now and no issues.

What are we looking at price wise for Atlas and install?

Atlas, new 4WD module and install was maybe 8500. New 4WD module out of a regular Rubicon is a must or the computer will never be happy. Took way too long to figure that out.

No indication that locker was on no lights nothing on off road pages.but yea that is what it felt like. Called a buddy he said this has happened to him about 12 or more times not even using 4wd just backing out of a parking spot he pulls back in shuts off the Jeep re starts it the service 4 wheel drive light goes out and everything is working properly very strange

I thought my tazer may be causing it but it is still doing it after tazer removed

If you order it and do it yourself $5,205.91 with shipping. I'll let you know how the install goes mid July.

Let me see if my Crescent wrench is still rusted together.

Just had the SAME thing happen in rural Northeastern Oregon two weeks ago. Difference being, didn’t matter how many times I turned off and on, it wouldn’t turn off and steer again.

Managed to limp it to Klamath Falls and slept in back in a gas station. Woke up in the morning and it was off and behaved completely normal again. Scared it was gonna get worse, drove all the way back to San Diego and it’s going to a local dealer tomorrow.

Was not off-roading or heavy on throttle when it locked up. Was simply driving on a long two lane highway for hours at light throttle.

We may all end up experiencing this as I hear about it more and more.

That is the proper solution for the hot steering issue. No fluid cooler is going to solve the problem, but will help. The issue is the pump motor itself and electronics are getting hot and you have addressed that. Do you have the fan motor connected to one of your accessory switches? Second question is the fan on the thermostat or do you just turn it on when you air down and lock up?

Bummer I waited about 45 minutes

I do have it hooked up to one of my AUX switches. Anytime I air down I turn the fan on. I run about 10 psi on 37x12.50 R17 BFG KM3 tires. Never had the hot PS light after installing the fan.

I just got my quote for an Atlas and PSC. I am not pulling the trigger yet, just want everything lined up for when I need it. Luckily, I am just going to use my AWE funds to purchase everything. I guess the unlucky part is there is only $73 in my AWE fund so far.

Just had it happen to me today backing out of a space at Costco. Obviously nothing other standard pavement driving. Seemed sluggish when I was backing out, with a short "sluggish" seize up and then it worked after a few second pause. Got on the road and noticed the Service 4WD light was on but it was driving perfectly. Drove about 20-miles home, with one traffic stop on the way, so I turned the ignition off and restarted with the light staying on. Got home and parked. 1/2 mile drive about 30-mins later and the light was off. Drove perfectly. ????? WTF. Jeeps, gotta love 'em and hate 'em, at the same time. Any ideas?

I think the transfer case motor on some of the TC’s are acting up. It was the same on the early production run on the TRX. Very similar symptoms.

4wd overheating temporary power reduced message

300 or so miles. Had and possible repaired a problem I was having. So roughly around the 300 mile mark I started getting the “4wd overheating temporarily reduced power” message. Searched and posted in forums where others were having the same issue. And was told possible fluid low issue...
