# THIS BULLETIN CANCELS AND SUPERSEDES CAMPAIGN BULLETIN 86C25(d) ISSUED JANUARY, 1992. THE SERVICE PROCEDURE
AND CLAIM INFORMATION SECTIONS HAVE BEEN REVISED. ALL COPIES OF BULLETIN 86C25(d) SHOULD BE DESTROYED.
REVISED INFORMATION IS SHOWN IN BOLD TYPE AND DENOTED WITH AND DENOTED WITH A #.
The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be
adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to repair within sixty (60) days after tender of a vehicle
is prima facie evidence of failure to repair within a reasonable time.
If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no
charge or to a refund of the purchase price less a reasonable allowance for depreciation.
To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair
their vehicle as soon as possible. As you will see in reading the attached copy of the letter that was sent to owners, the owners are being instructed to
contact the Chevrolet Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon service
date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.
Defect Involved and Vehicles Involved
DEFECT INVOLVED
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1985-86 P30 commercial model trucks with 350 gas
or 6.2L diesel engines, 1985-86 G30 model vans with 350 gas or 6.2L diesel engines, and 1985-86 C30 model trucks built without
heavy duty front suspensions. The left hand lower control arm can crack starting at the rear flange and progress to the ball joint mounting hole and
eventually cause the lower ball joint to separate from the control arm. If this happens, a loss of vehicle steering control can occur which could result in a
vehicle crash without prior warning.
To prevent this condition from occurring, dealers are to install a reinforcement brace to the left hand lower control arm.
VEHICLES INVOLVED
Involved are certain:
-
1985-86 P30 commercial model trucks with 350 gas (LT9) or 6.2L diesel (LL4) engines,
-
1985-86 G30 model vans with 350 gas (LT9) engines or 6.2L diesel (LL4) engines with or without school bus equipment (B3D) and without
recreational vehicle chassis modification (9A2) or heavy duty front suspension (F42), and
-
1985-86 C30 model trucks built without heavy duty front suspensions (F42).
