Yep, I've found that it is soon time to fix that stuck front diff lock,
so it will be ready and working by the time winter sets upon us (luckily
at least 3 more months). The prob is, I don't know how to do it, and I
don't have the Bentley manual. I assume that the lock is stuck from lack
of use, not a vacuum leak. The lamp blinks as it is supposed to. The
rear lock works perfectly. I have the instructions found at Steve
Schwenks site, but those are for the rear lock, and without pics. So,
these are my questions:
1) Can anybody tell me how to do the front diff lock?
2) Does the Bentley cover the front diff lock?
3) The rear lock?
4) Is anybody willing to scan all relevant pages from the Bentley and
send them to me?

That's a lot of questions, but I need info on this, so I wont screw up.
I have two manuals that cover the most of the bus, but none of them
includes the Syncro stuff well (the Haynes not at all)
