Hi there,

Yes, saw this just a couple of weeks ago (diff lock
not wanting to disengage).  The problem turned out to
be the diff lock servo.

There is a red "seal" around the shaft.  This seal was
torn, so that the proper vacuum could not be
maintained to disengage the diff lock.

You can either buy a new servo from one of the list
dealers or buy just the seal from Derek Drew.

To verify which you need, first pull your servo and
check the condition of your seal.  In the case I had,
vacuum could be maintained in one direction (to engage
the diff lock), but failed to maintain in the other
direction (disengage).

The westy stepped up to the test last week with over a
1000 mile road trip and not a problem (major anyways).
The westy crusied at 65 mph on the highway no problem.
Over the course of the trip there were brief periods
of hesitation...Maybe 10 times and very brief.  There
were however two noticable problems. 1. It appears as
though the rear differential won't unlock.  I checked
the archives and have found some proceedures to
troubleshoot the diff lock. However it appears as
though the troubleshooting is to address differential
locks that won't engage...Mine wont release (any
ideas?). 2. There was also a little idle problem where
the idle would bounce about 50 to 100 rpms during a
stand still. Running, the westy ran fine. The idle
bounce was also intermittent and occured probably 50%
of stops. Does this sound like the idle control????
The idle control behind the tail light has been
changed, but not the switch itself. Think I should
just let this one be and not open a larger can of
worms??Thanks again everyone.JC
