TSB 83-03-24 TRANSFER CASE - NP208 - RANGE FORK AND NYLON ANNULUS HUB WEAR


LIGHT TRUCKS 1982-83 BRONCO, F150-250 (4x4)

New Process Gear Model 208 Transfer Cases on the above vehicles built after January 19, 1982 have a new range fork and annulus gear assembly design.

The annulus gear hub and web assembly (7B066) can be damaged when the transfer case is operated with low lube fluid levels or with a rough surface finish fork or thrust washer. This will result in transfer case shifting difficulties. The damaged nylon hub will appear to be melted or severely scored and must be replaced. The range fork (7289) and thrust washer (7D484) must also be replaced since surface finish damage or sharp edges created during the prior condition can cause accelerated wear of the new hub and web assembly and result in a repeat service. The transfer case should be refilled with 7 pints of new automatic transmission fluid lube (XT-2-QDX) and checked for any leaks. With the vehicle in a level position, the lube fluid must be up to fill plug opening.
