NOISE - CLATTERING/BANGING OF TRANSMISSION/TRANSFER CASE DURING BRAKING
LIGHT TRUCKS 1981-83 F-150/350, BRONCO
Gear "banging" type noise during braking can be caused by rear wheel brake shudder "shaking" the transmission/transfer case even if it is not felt by the
driver. The brake shudder may be caused by the rear wheels warping the brake drum. For F150 and Bronco with styled wheels, refer to TSB-82-10-15.
For F250/350 with standard wheels, refer to TSB 83-7-19. Transmission or transfer case service actions should not be performed until confirming that
brake shudder is not the causal factor.
