Transfer Clutch: Inspection

WARNING: This page is about a different car, the 2003 Subaru Impreza. However, it is still accessible from the selected car via links, so may be relevant.

Check the drive plate facing for wear and damage.
Check the snap ring for wear, and the return spring for permanent set, breakage and deformation.
Check the D ring for damage.
Measure the extension end play and adjust it to within specifications. See ADJUSTMENT , Transfer Clutch.

Inspect clearance between snap ring and pressure plate.
Before measuring clearance, place the same thickness of shim on both sides to prevent pressure plate from tilting.
If the clearance is not within specification, adjust it by selecting a suitable pressure plate on the transfer clutch piston side.

Check if tight corner braking does not occur when the vehicle is started with steering wheel held at fully turned position. If tight corner braking occurs, perform the following procedures.
1. With the steering wheel held at fully turned position, drive the vehicle in "D" range and with vehicle speed at approx. 5 km/h (3 mph) in both clockwise and counterclockwise directions for approx. ten times each, while repeating acceleration and braking intermittently.
2. If the tight corner braking still persists, drive the vehicle again in a circle for several laps.
