# Product Safety - Power Steering Gear Lower Pinion Bearing Separation

Subject: | 02049 -- Power Steering Gear Lower Pinion Bearing Separation

Models: | 1996-1998 Chevrolet Cavalier

| 1996 Chevrolet Lumina APV

| 1997-1998 Chevrolet Venture

| 1996-1998 Pontiac Sunfire, Trans Sport

| 1997-1998 Pontiac Grand Prix

| 1996-1998 Oldsmobile Silhouette

### Condition

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1996-1998 Chevrolet Cavalier; 1996 Chevrolet Lumina APV; 1997-1998 Chevrolet Venture; 1996-1998 Pontiac Sunfire, Trans Sport; 1997-1998 Pontiac Grand Prix; and 1996-1998 Oldsmobile Silhouette vehicles. Some of these vehicles may have a condition where the lower pinion bearing in the power steering gear may separate. Most reports indicate the driver experienced an intermittent loss of power steering assist when making left turns, usually at low speeds. Power assist is normal in right hand turns. When trying to turn left, some drivers could experience higher resistance or, in a few cases, assist towards the right. If this happens while the vehicle is moving, a crash could result.

### Correction

Dealers are to inspect the condition of the lower pinion bearing and replace the lower pinion bearing, or in a few cases, replace the rack and pinion steering gear assembly.

### Vehicles Involved

Involved are certain 1996-1998 Chevrolet Cavalier; 1996 Chevrolet Lumina APV; 1997-1998 Chevrolet Venture; 1996-1998 Pontiac Sunfire, Trans Sport; 1997-1998 Pontiac Grand Prix; and 1996-1998 Oldsmobile Silhouette vehicles built within these VIN breakpoints:

#### 1996-98 Cavalier and Sunfire - Lower Pinion Bearing Inspection

The following service procedure is for inspection of the lower pinion bearing and can be performed without completely removing the steering gear from the vehicle.

Important: Tool J 44714-A is required to perform this service procedure.

1. Open the hood.
2. Raise the vehicle on a suitable hoist and support.
3. Remove the two bolts attaching the steering gear to the engine frame (cradle).
4. Release the brake pipe from the retainers at three locations on the engine cradle.
5. Remove the steering gear from the engine cradle mounting brackets and reposition to access the lower pinion shaft dust cap.

Important: When removing the dust cap in the next step, watch for loose ball bearings that may have separated from the inner and outer pinion bearing races.

6. Remove the dust cap (3) from the steering gear housing (2) and inspect for loose ball bearings. Refer to Figure 1.

• | If no ball bearings were found in the dust cap, proceed to the next step and replace the lower pinion bearing.

• | If one or more ball bearings were found loose in the dust cap, proceed to the section in this recall bulletin title "Steering Gear Replacement" for the described vehicles.

Notice: Failure to perform the next step may result in damage to the lower pinion bearing removal tool (J 44714-1).

7. Loosen the adjuster plug lock nut (3) and the adjuster plug (2). Refer to Figure 2. Do not remove the plug.

Important: If the stub shaft is not held in the next step, damage to the pinion teeth will occur.

8. While holding the stub shaft (1), remove the retaining nut (4) from the pinion shaft. Refer to Figure 1. Do not reuse the nut.
9. Remove the lower retaining snap ring (1). Refer to Figure 3.
10. Carefully insert the legs (1) of pinion bearing remover J 44714-1 (included in J 44714-A) between the balls in the lower pinion bearing. Refer to Figure 4.
11. Assemble the center bolt (2) into the forcing screw (1) of the tool. Refer to Figure 5. Back the center bolt at least 25mm (1 in) inside the forcing screw.
12. Assemble the forcing screw (2) inside the puller legs (1). Refer to Figure 6. Finger tighten the forcing screw to push the puller legs against the bearing.
13. Using a 24mm wrench to hold the forcing screw, use a 17mm socket to tighten the center bolt until the bearing is removed from the gear housing. Refer to Figure 7. Do not reuse the bearing.

Important: Inspect the gear housing to ensure that no parts of the old bearing remain.

14. Apply a small quantity of lubrication (e.g. multi-purpose grease or power steering fluid) inside the housing bore where the new bearing will be installed.
15. Center the new bearing over the pinion thread. The bearing can be installed with either side facing outwards.
16. Place the bearing installer (1) J 44714-2 (included in J 44714-A) over the pinion thread. Refer to Figure 8. If necessary, use the extension J 44714-3 included with the installer. Lightly tap with a hammer until the bearing is seated in the housing.
17. Install a new snap ring. When properly installed, the large lug (1) on the snap ring must be on the right side as shown in Figure 9.

Important: If the stub shaft is not held in the next step, damage to the pinion teeth will occur.

18. While holding the stub shaft (1) install a new retaining nut (3) on the pinion shaft. Refer to Figure 10.

Tighten
Tighten to 30 N·m (22 lb ft).

19. With the rack centered in the housing, tighten the adjuster plug (2) to 10 N·m (88 lb in), then back off 40 to 50 degrees. Refer to Figure 11. Check the torque on the pinion. Maximum pinion preload torque is 4 N·m (35 lb in).
20. Tighten the adjuster plug lock nut (3) firmly against the steering gear housing while holding the adjuster plug (2) stationary.
21. Install a new dust cap (2) to the steering gear housing.
22. Reinstall the steering gear in the engine cradle mounting brackets.
23. Reattach the brake pipe to the retainers on the engine cradle.
24. Install the two bolts that attach the steering gear to the cradle.

Tighten
Tighten the bolt to 120 N·m (88 lb ft).

25. Lower the vehicle.
26. Check the power steering fluid and add if necessary

Important: It is NOT necessary to check alignment or toe-in when performing this procedure because the position of the engine frame (cradle) to the body has not been disturbed.

January, 2003

Dear General Motors Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

### Reason For This Recall

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1996, 1997, and 1998 model year Chevrolet Cavalier; 1996 model year Chevrolet Lumina APV; 1997 and 1998 model year Chevrolet Venture; 1996, 1997, and 1998 model year Pontiac Sunfire, Trans Sport; 1997 and 1998 model year Pontiac Grand Prix; and 1996, 1997, and 1998 model year Oldsmobile Silhouette vehicles. Some of these vehicles may have a condition where the lower pinion bearing in the power steering gear may separate. Most reports indicate the driver experienced an intermittent loss of power steering assist when making left turns, usually at low speeds. Power assist is normal in right hand turns. When trying to turn left, some drivers could experience higher resistance or, in a few cases, assist towards the right. If this happens while the vehicle is moving, a crash could result.

### What Will Be Done

Your GM dealer will inspect the condition of the lower pinion bearing in the rack and pinion steering gear assembly and replace the lower pinion bearing, or in a few cases, replace the rack and pinion steering gear assembly. This service will be performed for you at no charge .

### How Long Will The Repair Take?

The length of time required to inspect and replace the lower pinion bearing is approximately 30 minutes for the Cavalier and Sunfire, and 2 hours for all other vehicles. A small number of vehicles will require replacement of the rack and pinion steering gear assembly, which will take approximately 2 to 2 ½ hours to perform the service correction. . Additional time may be required to schedule and process your vehicle. If you dealer has a large number of vehicles awaiting service, this additional time may be significant. Please ask your dealer if you wish to know how much additional time will be needed to schedule, process and repair your vehicle.
