THIS BULLETIN IS BEING REVISED TO CHANGE PRODUCT IDENTIFICATION CRITERIA AND TORQUE SPECIFICATIONS. THIS
BULLETIN REPLACES BULLETIN 93-5-5 ISSUED 3/93. PLEASE DISCARD BULLETIN 93-5-5. THIS BULLETIN INCORRECTLY SAID
REPLACES BULLETIN 93-3-5 LAST WEEK. PLEASE MAKE THIS CORRECTION.
This bulletin serves to cancel and supersede torque specifications for the rear wheel hub and bearing assembly attaching bolts found in section 3D of the
1990-93 Trans Sport Service Manuals. The bolts attach the rear hub and bearing assembly to the rear axle (four on each side).
Rear hub and wheel bearing assembly attaching bolts for all Trans Sport vehicles should be torqued using the following guidelines:
^
Vehicles manufactured from model year 1990 through 1992 require a torque specification of 63 N-m (46 lb.ft.).
^
Vehicles manufactured in model year 1993 and beyond require a torque specification of 82 N-m (61 lb.ft.).
This change is a result of the required torque distinction between unpainted and painted bearing surfaces and not the type of bolt being used.
The 1990-93 Service Manual for Section 3D should be updated.
