#40 of 60 4x4 issues please read
Dec 29, 2011 (6:18 pm)
I have a 1988 expedition with 180,000 miles. It runs like a tank usually. Today after returning from a 20 mile trip to the office I arrived home to find I needed to go out to pick up dinner. I started the truck and started down the road only to hear a grinding noise and felt the truck lurch forward. I pulled over and started out again same result. The dash light shows 4x4 low but the switch isn't set in 4 wheel mode. Any ideas?

Sounds like the a4wd is engaging. Did you try running it through the 4wd selections, i.e. put it in 4 hi, then 4 lo? See if that gets it back to where it belongs. Your '98 has A4wd and no 2wd drive, correct?

My 98 has 2H A4WD 4H and 4L. I haven't had it out of 2H in over a year. Tried switching through 4W modes no change still have light saying 4x4 Low Range.

Could this be the electronic shift motor? Can I test to prove its not working?

Yes, but usually the failure is that it doesn't engage, not that it randomly does. Not sure how you would go about fooling it into disengaging. Did you try 4x4 just before this happened?

The solenoid is what would send the impulse to the motor to move. If you didn't switch it, there is no reason for it to be in 4WD. Are you still driving it?
The motor is a plug and play and unbolts pretty easliy. You could take it out and see if there is anything going on.

Hi I have this problem with my truck I had this happen before but it went back to awd. I was driving in the HWY. and as I exit and stop it made a loud sound and it seem like it engage in 4x4 but it was still in awd road conditon a little slippery. so I parked and check it see if anything came lose or broken,nothing that I could see so climb back an did a test on my awd,4h and 4lo to see if I could disngauge or something .so I thought it was the transfer motor and to my luck it wasnt so dont know what else to do or replace,..low on $ has any one had this problem..any sugestions

4WD will not engage and no light on the dash. Had GEM problem from windshield leak but repaired leak and electrical is functioning well for over a year. I checked one 30-amp fuse and it looked fine. I would like suggestions of things to check before I start spending money. Thanks in advance.
