ALL CHEVROLET DEALERS
A rattle or clunk noise may be transmitted up from the steering column area on a 1982-83 Celebrity or Citation equipped with power
steering while driving on a rough road or hitting bumps. This condition may be caused by the following conditions:
1.
Rack Bearing Adjustment
Bump force on the steering rack may compress the rack bearing adjuster spring resulting in a clunk or rattle. Adjust the rack
bearing adjuster plug "back off" to the minumum specification of 500 to correct. Adjustment procedure is outlined on Page
3B2-11 of the 1983 Celebrity and Citation Chassis Service Manual. Back off specifications is 50~ to 70~.
2.
Intermediate Steering Shaft Assembly
Dealer Technical Bulletin 82-T-109 describes a lower steering column rattle which can be repaired by installing a spring on the
shaft assembly slip section.
Instances can be encountered where due to tolerances in the shaft assembly, the spring may not completely eliminate the noise.
The spring is installed on 1983 production shafts by Saginaw Steering. If the noise is diagnosed as being from the shaft assembly
and the spring is already installed, replace the intermediate shaft assembly. This would apply to 1982 and 1983 models.
3.
Clunk Noise Transmitted Into the Steering Gear Assembly
A condition could be encountered, for example, where a clunk noise in a McPherson Strut may be thought to be coming from the
steering system.
Eliminate suspension noise potential sources such as the struts or springs before diagnosing the steering system for rattles.
4.
A Rattle or Clunking Noise from the Rack and Pinion Assembly May Also be Caused by:
a.
Power steering pressure hose touching other parts of the car.
b.
Tie rod end loose.
c.
Rack and pinion attachment loose.
