2001-2005 Optima (MS) Subframe Revised Service Procedure (General Information - 026)

- Description

During a service procedure that requires the subframe to be removed from a 2001-2005 Optima (MS) (V-6 or I-4), an improved service procedure has been developed to enhance service efficiency. Prior to the release of this service bulletin, the 2001-2005 service manual required the removal of the rack & pinion with the subframe. The improved procedure outlined in this TSB reflects the removal of the subframe with the rack & pinion retained with the vehicle. The modification of this service procedure includes a two (2) wheel alignment within the allowed labor time.

SERVICE PROCEDURE:





1. Place the vehicle on a hoist and record radio presets. Open the hood and remove the battery from the vehicle. Remove the air cleaner from the vehicle.





2. Remove the two (2) main wiring mounting nuts and allow sufficient free-play of the main harness for the remainder of this procedure.








3. Remove the rear transmission mounting bolts, remove the rear transmission mount. Install an upper engine / transmission support fixture.

6. Remove the two (2) right-hand side rack & pinion mounting bolts.
