Inspection of rear suspension
|
Saab 9-5, VIN W3050321 - W3053596.
After assembling the rear suspension/damper unit, the fit of the suspension on the lower spring seat has been poor on
a small number
of cars. This has meant that the contact surface of the spring against the damper has been smaller than calculated.
45 65 446 Spring, code BJ
45 65 438 Spring, code BH
Gauge - supplied by the importer
Cars within the above VIN interval must be checked to see if the rear suspension fit is within tolerance. This can be done without removing the spring and damper.
