Subject: Re: Syncro tranny whine
Content-Type: text/plain; charset=us-ascii
Welcome to the club, Mark. These whines and noises will drive you nuts
there are so many potential causes, etc. May I offer a piece of
advice. Find a mechanic who KNOWS vanagons, preferably someone who only
works on vanagons and VWs. He or she will be able to tell you much more
after a 10 minutes test drive than 2 weeks of sepculating on the list
and on your own will.
Tim Smith kindly responded to my despondent plea for help with my
tranny/drive line noise. He had an excellent suggestion that would be
helpful to everyone. What we need is help from those several gifted
listmembers out there who really know transaxles/differentials/cv
joints/wheel bearings, etc. (i.e., the pros who have a developed
knowledge base from years of working on vanagons on a daily
basis...well, I guess a lot of us would quailfy there, but you know what
I mean.)
We need a list of what noise/symptoms various components make when they
are beginning to fail, especially for the syncro. For example:
noises/symptoms for (1) transaxle main shaft bearing, (2) ring and
pinion, (3) Pinion bearing, (4) 3-4 slider hub, (5) cross-country
housing (if any), (6) center drive shaft, (7) CV joints, (8) wheel
bearings, (9) motor mounts, (10) exhaust touching other components,
etc. [ I heve limited knowledge here... don't even know exactly what
components should be on the list]
This is important for syncro owners for several reasons. If you
continue to drive with some of these parts going, you will do severe
additional damage to other components of the transaxle. For example, if
you continue to drive with a worn pinion bearing, you will damage the
ring and pinion gears. Big deal you say? You should see the prices of
some of these components. Parts alone can take you over $1000 no
problem. Not only that, you cannot get cores for these anymore. I have
heard that a rebuildable...not rebuilt, but rebuildable... core can cost
$900, if you're lucky enough to find one. If you continue driving with
certain components going, you are going to need one.
The pros who help us out here could benefit also. A list posted in the
archive and under FAQ or something on one or more of the sites such as
Coyotes would generate business for those who do this professionally.
Their contribution to the symptoms list could be acknowledged right on
the list with phone numbers, etc. And some of these same individuals
who get hounded repeatedly with the same questions could just refer
people to the symptoms list, or others could.
I am already overwhelmed with the head survey and the bios for the trip
to the end of the world or I would volunteer. Any takers?
