Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
Important:
• | A normal shim pack will leave at least two threads of the bolt
exposed beyond the nut. |
• | If two threads cannot be obtained, check for a damaged control
arm or related parts. |
• | The difference between the front and the rear shim packs must
not exceed 7.62 mm (0.30 in). The front shim pack must be at
least 6.09 mm (0.24 in). |
• | Always tighten the thinner shim pack nut first in order to improve
the shaft to frame clamping force and torque retention. |
