Defect
THE NUT ON THE CARRIER SUPPORT BOLT ASSEMBLY MAY BREAK WHICH WOULD ALLOW THE ENTIRE WHEEL AND TIRE ASSEMBLY TO SEPARATE FROM THE VEHICLE.
Remedy
DEALER WILL REPLACE THE TIRE AND WHEEL CARRIER BOLT ASSEMBLY AT NO CHARGE.
Defect
THE LEFT AND RIGHT FRONT SUSPENSION CROSSMEMBER STRUT RODS, WHICH GIVE ADDED STRENGTH, MAY HAVE BEEN OMITTED DURING ASSEMBLY. CONSEQUENTLY, A FRAME CROSSMEMBER CRACK COULD EVENTUALLY DEVELOP AT THE FORWARD VERTICAL FRONT SUSPENSION BOLT.
Remedy
DEALER WILL INSTALL THE NECESSARY FRONT LEFT AND RIGHT RODS WITHOUT CHARGE TO OWNER.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
Yes — NHTSA lists 2 recall campaigns affecting the 1978 GMC C35. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
