I am having a problem with the front not disengaging when it is in A4WD. The motor is working as I can go into 4WD Lo and come back out and I have also had someone watch to see if it is working. Any help or suggestions greatly appreciated.

 

Have you pulled the motor off the back and switched between the different positions to see if the motor is moving into A4WD mode? Could also be the switch itself.

 

What symptom makes you think it is not going to 2wd? Tire scrubbing when turning in the dry?

 

I have pulled the motor and the is switchinbg as it is supposed to. It will go into 4WD Lo and indicate such on the dash and will then switch back out and indicate A4WD on the dash but the front end is still locked in which is evident when having to make turns on dry pavement.

 

Gotcha, sounds like something inside the transfer case. I know the 1356 has sliding clips that get wore down over time, but I've never messed with the BW 4406 yet. Sounds like you might have to take it apart and see what's going on inside it.

 

On the '99 the front axles,diff and driveshaft spin regardless of the setting. The only disconnect for the front drivetrain is in the t-case.

I would be more concerned to know what happens on the shift motor when you go from a4wd to 4hi, switching into 4lo is a little different than a4wd to 4hi. I would just make sure it isn't that shift motor or the switch before removing a t-case.

 

Thanx for the info will have to check this out.

 

How do you check out how it is acting? Can I pull the motor off and watch what happens when switching from a4wd to 4hi?

 

I checked the motor and switch and they are both working fine. The t-case was in a4wd when it locked up and not in 4hi. I had used the 4hi about a week before it locked up on me.

 

Pull out fuse #104 from the under hood fuse box. Then go for a drive and see if the front end frees up. It's safe to drive with the fuse out.

 

I tried this as well as pulled #23 and neither of these made any difference. You can hear clicks in the t-case while switching from a4wd to 4hi and back to a4wd but the front end stays engaged. I appreciate all the suggestions so far but still frustrated.

 

Since pulling fuse #104 doesn't release the front drive system, you have a mechanical failure within the transfer case.

 

I was afraid of that but apprecdiate all the help and advice.

 

I must apologize as my son just informed me that he did not test drive the Expy after pulling the fuse he saw that the shift motor wasn't working and assumed that it was not the problem. You and I both know what ***ume means. After he gets home we are goint to try the fuse situation again and then see what happens. Again I must say thanks.

 

Besides the shift motor, fuse #104 also powers the front clutch inside the transfer case. So without power, the clutch should not be able to stay engaged unless it's locked in place mechanically. Just letting you know how I'm analyzing this.
