Some 1988 celebrity models assembled at plants indicated below may exhibit a ride characteristic referred to as diagonal body/ride motion that may be attributable to mislocated cradle steering gear and/or lower control arm attaching holes.

This diagonal body/ride motion may be apparent when a vehicle is driven over road swells/dips at highway speeds, while maintaining the steering wheel in a straight ahead position. As the vehicle proceeds through this type of road irregularity, the normal vertical body/ride motion may be accompanied by a lateral body/ride motion that generates the sensation that the vehicle body is moving in a diagonal direction.
Vehicles exhibiting this condition may be repaired by replacing the front cradle assembly following applicable shop manual procedures.
New cradle assembly part numbers are indicated below by engine RPO and are available from GMSPO.
