S10/T10 P/U 4WD V6-4.3L VIN X (1996)
Fender: All Technical Service Bulletins
Front Tire Tread - Contacts Inner Fender Bolts
File In Section: 10 - Body
Bulletin No.: 66-20-03
Date: November, 1996
Subject:
Front Tire Tread Contacts Lower Inner Fender Bolts
(Replace Lower Bolts)
Models:
1994-96 Chevrolet and GMC T Models with High Wider Option (RPO ZR2)
Condition
Some owners may comment that when turning, the front tire tread rubs against the inner fender lower bolts and damages the tread.
Cause
The installation of non-OEM wheels and/or tires may contribute to tire to inner fender bolt contact. Also, if the steering alignment, including suspension
"Z" height is not within the specifications in Section 3A of the S/T Truck Service Manual, tire tread to inner fender bolt contact can occur.
Correction
Replace the two lower rear inner fender Hex Head Bolts with Pan Head Bolts. These bolts provide additional tire to bolt head clearance and reduce the
possibility of tread damage.
Service Procedure
Notice:
Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application General
Motors will call out the fasteners that require thread lockers or thread sealant. Unless otherwise specified, do not use supplemental coatings (paints,
greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque
and joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following
these instructions can help you avoid damage to parts and systems.
1.
Remove the two rear lower inner fender to wheel house panel bolts.
2.
Install new bolts (P/N 15715627) and torque to 29 N.m (21 lb ft).
