Does that mean any Astro Van or Bravada T-case will work in a syty as long as the tail housing, rear output shaft, yoke and drive chain are swapped over?
not sure why you would need to swap the chain
2 different part numbers for the drive chain per above:
Syty and Bravada: 272888t
So if you buy an Astro Van transfer case, it looks like the chain would need to be swapped too.
^-------The Borg-Warner 4472 is a three-piece aluminum, chain driven, viscous clutch-type transfer case. This is used in a system in which all-wheel drive is always activated. The all-wheel drive is automatic and has no external controls.
The viscous clutch used in the 4472 is a torque distribution device and is non-serviceable. The internal construction of the viscous clutch consists of alternating plates that are connected to the front and rear outputs of the transfer case. The clutch is filled with high-viscosity oil which flows through slots in the plates. The oil's resistance to sheering causes the plates to transmit torque at the needed ratio to the front or rear wheels.
All of them, or just the early ones like the Bravadas? I don't remember. If I'm wrong, fix it for me please. This thread is confusing enough as it is. Thanks.
