4wd light on and off.

[rejeep]

ever since I got my Jeep while driving it the 4WD indicator light will go on and off. If the jeep is in 2wd/4wd the same thing happens.. any ideas?

[Stumpy]

mine only does that when i turn the climate control to off..lol :D :roll:

 

so the only thing i can think is a vacuum leak or wire/switch messing up

[CWLONGSHOT]

YUP, its likely vacuum!!

I would start with the lines, they are and get brittle with time.Then remove and clean the vacuum acuater on the front axle. Then if that dosen't fix it, change out the unit on the X-case. Then, one or two swift kicks in the right rear tar, open the wallet, get the esentials catalogue, and order a posi-lok!! :shock: :D :D

 

I had simular problems, I did what everyone suggested and got it to work prety good. I did not find the problem till I tore into the acuater itself. It wasnt repairable. the Orings where shot for too long and eroded or allowed the bore to erode to the point where it couldn't hold vacuum between the "O" rings. It would slowly pull the collar out of 4WD but not allow enough of a seal to trigger the vacuum switch telling the driver it was out of 4WD.

 

Problems GONE now!!!

Hey... is that the posi-lock I was supposed to get....

[bhawkin2]

Has anyone used the NEW Posi lock, it has no cable just lockes the collar on the axle shafts permanatly it sell for around $100 instead of the cable operated one for $190.

Or you can just take the CAD cover off, slide the collor over to the "lock" position, and then re-install the cover upside-down. Haven't tried it yet myself, but it's gotta be the easiest fix out there. :D

Jeep on!

I READ on one of the forums I visit abou just flipping the VD housing cover over, and it locking the 2 shafts together. I have also read of ppl using washers, and the what not. Do some research before you shell out $100 for something you can do for almost nothing.

I often flip my disco over and it holds the shafts locked together perfectly. Takes about 5 minutes before and after the trail, until I get my D44 installed. I wouldn't spend $100 for something that does the same thing.
