Special model VW Syncro Doka for hunters and sportsmen

A device in the front differential of a Syncro that provides the switching action between the rear diff/wheels and the front.

Shaft that drives the differential in a vehicle

In Gerry’s preserved FAQ alignment article, “Camper model” refers to the heavier Vanagon Syncro camper configuration, with separate alignment values from lighter non-camper vehicles. A Gerry discussion on 15 October 2003 about the “official” Syncro alignment specs quotes the chart for 1986–1991 Syncro campers with dual batteries up front; a 1999 thread separately asks about an almost-empty 1986 Syncro. These historical sources show why the exact load and configuration matter, not a current alignment specification. Use service data for the specific vehicle.

Shaft that transmits power from the engine to the gearbox

Type of differential that limits the slip between the wheels

In a Syncro drivetrain, a driveshaft decoupler disconnects the prop shaft so the front axle is no longer driven through it; it is not the front differential lock. A Gerry discussion on 16 May 2004 compares the original non-viscous-coupling layout, which used a driveshaft decoupler, with viscous-coupling Syncros while debating front-lock behavior. The thread is historical community discussion, not a retrofit procedure; identify the drivetrain configuration before interpreting parts or controls.

Set of brake shoes for Vanagon/T25 models, excluding Syncro with 16-inch wheels

The four-wheel drive version of the Vanagon , made between 1986 and 1991. using a viscous coupling arrangement, the front wheels could be made to automatically provide pulling power (at any time the rear wheels began to slip or spin). This term also applies to the four-wheel drive EuroVans , which are unfortunately not imported into the United States.

Exhaust pipe located before the rear silencer in Vanagon/T25, excluding Syncro models

( Constant Velocity Joint ) One of the small circular devices at an end of an axle on a bus . Buses , Vanagons , and EuroVans have four of these, while the Syncro Vanagons have a total of eight. These are necessary to allow the axle to move up and down while still turning to propel the car. the joints need to be keep greased to function properly. when they are worn, they make a knocking-noise that strikes fear into the hearts of bus owners everywhere. Microbuses do not have CV joints, but use a 'swing-axle' and reduction gear box instead.
