If nothing is working with your diff locks, it could be a problem with the rubber membrane in the Transfer Case. To test it, pull off the line on the center diff solenoid, and try to pump up a good vacuum with a tester. If you can't create a good vacuum (15 - 20 inHg), or it is not stable, you might have a leak in that membrane. Please remember, if the center diff is not engaged fully, none of the other diff lock will be activated. The part# of the membrane: A463 284 00 94 (IMG_0593.JPG) (IMG_0594.JPG) Attachments ---------------- IMG_0593.JPG (52KB - 1 downloads) IMG_0594.JPG (62KB - 1 downloads) | ||

I would add to this- whenever you replace the center shaft, always makes sense to replace this diaphragm too. Center shaft has to come out to get to this part. I learned that from DrG. | ||

Yes, the front driveshaft has to come off, then the driveshaft flange on the xfer case. The rest is easy. | ||
