LIGHT TRUCK:

1988-94 F SUPER DUTY

ISSUE:
The rear axle shaft/hub bolts may loosen and leak axle lube. This loosening can occur due to increased torques at the rear wheels.

ACTION:
Install new higher strength flange head bolts and improved cellulose gaskets, which clamp the joint together tighter. Refer to the following service tips and revised torque specifications.

^ Do not use higher torques specified for these bolts on previously specified hex head bolts.

^ Always replace the bolts and gaskets together rather than reusing them when servicing the wheel end.

^ The new cellulose gaskets and new flanged head bolts are designed to be used together; therefore, neither part should be used with older stock parts.

NOTE:
WHEN REMOVING THE BOLTS, LOOSEN THEM BY HAND BEFORE USING AN IMPACT WRENCH. THE SHOCK LOAD APPLIED BY A POWER TOOL MAY CAUSE THE BOLT TO SNAP BEFORE IT RELEASES.

NOTE:





WHEN SERVICING THE REAR AXLE HUB OR SHAFT, REPLACE THE BOLTS AND GASKET WITH THE NEW PARTS. USE THE NEW TORQUE SPECIFICATIONS.

NOTE:
SPECIAL LUBRICANTS ARE REQUIRED FOR DANA FULL FLOAT REAR AXLES. USE FORD HYPOID GEAR LUBE (C6AZ-19580-E OR EQUIVALENT), OR FOR EXTREME SERVICE APPLICATIONS, USE FORD HIGH PERFORMANCE REAR AXLE LUBE (F1TZ-19580-B OR EQUIVALENT). REFER TO TSB 92-3-11 FOR ADDITIONAL LUBRICANT INFORMATION.
