Have you looked under there to see if anything is leaking?

 

I've looked under there and can't see where anything has been leaking and there is no puddle in my driveway at all.

Update: This morning I stopped at the donut shop on the way to work and tried again because I actually needed it. 4HI did the same thing, but 4LO blinked for a minute then the yellow 4WD light came on and stayed on and the drivetrain diagram disappeared. Then I couldn't get the SOB to go back to 2wd. I think the 4WD disengaged because I could get the rears to spin, but the light stayed on and is still on.

 

1. Check wheel sensors
2. It may be possible your front dif grenaded.
3. When you put on the leveling kit did the CV shaft slip out?

Sounds like it had been working fine, what happened in the period between last use and this one? Did you back up aggressively or hit any snow drifts?

 

I have used my 4WD many times since I put the leveling kit on and it has worked flawlessly. I drove home from church on ice in 4HI Sunday morning, parked the truck all day, then that evening I drove to my parents and back in 2WD and just needed 4HI for the driveway at my house. All mild driving yesterday. No goofing off or hitting drifts.

 

I had that exact issue before and I had to get the electronic control module on the transfer case replaced under warranty. Never had an issue since the module was replaced. The only times I have heard of the wheel diagram disappearing, the electronic module was at fault. Sounds like you are in for a trip to the dealership.

 

well, the other time it wouldn't engage was when my rear e-brake pads delaminated form the shoes, spun and took out my wheel sensor. you can unbolt that from the back plate to inspect without taking everything aprart though.

but, if it's trying to engage I doubt it's the sensor because if it was broken it wouldn't even try..

 

I just took my 04 to dealer today for same 4x4 issues, was told I need new front differential $1900!!!

 

Holy cow!! I guess I'll be taking a trip to the dealership this weekend in Tulsa.

 

Same 4WD indicator issue with my 05. Since it is under warranty guess ill be makin a trip to shop.
I would think that running it in 2WD will not cause any damage as it surely seems electrical in nature.
Really want to wait till Christmas break if possible. Thoughts?

 

I'm continuing to drive mine in 2wd and nothing has changed or gotten worse. Doesn't mean it won't, I just don't want to pay a repair bill right before Christmas.

 

Well I got a call Thursday and they said they replaced some weight sensor (their words) and that worked about 4 times in and out of 4wd then threw a code. Called them back today and they said they found a bunch of metal in my transfer case and I needed a new one for $2500 out the door. He ordered one and it should be here by the weekend. I really don't want to get raped by the dealer so I'm wondering if my brother and I can install a new one? We're both fairly mechanically inclined and took auto service at tech in high school. So how hard is the t-case to replace?

 

That sounds outrageous! I'd get a second opinion and never take anything to the dealer. They rape people and I'm sick of hearing stories like this! Bunch of bastards!

 

It really depends on how well equipped to do the work you are. If you have the mechanical skills and the tools to do the job I'd say take it on and save a little bit of money.

I can help you with the service manual information as well.

 

Was that price just for the dif or installed?

Mine was done under warranty but I think it was only 12-1500.

 

That is the price for everything out the door. That sensor and a new transfer case. I didn't ask about just the transfer case. I was kind of in shock when he spit that number out.

 

so i thinking front diff is junk or the front axle on the right side cause have grinding noise and all that good **** and no four wheel , hoping i can get nissan do somthing about is cause of it being know issue and my truck only having 46k on it and being under 10 years old i'm hoping they do something for me if want me to buy another one !
