Spicer® Chassis Replacement Upper Control Arm Assembly for Silverado Trucks, Hummers

McHENRY, Ill. (March 29, 2006) - Affinia Under Vehicle Group has introduced a 
Spicer® Chassis replacement upper control arm assembly to address ball 
joint/control arm failure in ¾- and one-ton Chevrolet/GMC Silverado trucks 
and select Hummer vehicles.

The exclusive Spicer Chassis upper control arm assembly - part number 502-1083 
- features the Spicer professional grade ball joint and new control arm 
bushings.

Spicer Chassis engineers designed the assembly to correct problems discovered
 with OE control arms that occur in extreme operating conditions and situations
 when the OE ball joint fails and distorts the case of the joint. When the ball
 joint is pressed out of the stamped control arm, the contact area is distorted
 and replacement of the ball joint is difficult or impossible. 

"Installing a ball joint into a damaged or distorted control arm can result in 
premature failure or serious damage to the vehicle," said Ken Myers, marketing 
manager for Affinia Under Vehicle Group. "Our Spicer Chassis replacement upper 
control arm offers technicians a complete solution in a premium quality, 
professional grade product."

Not every vehicle will experience damage to the OE control arm under extreme 
operating conditions, says Myers.

"In situations where the control arm is still serviceable, Spicer Chassis 
offers the 500-1104 replacement ball joint, providing installers with a 
choice in servicing affected Silverado trucks and Hummer vehicles," he said.
