1998-2002 Oldsmobile Intrigue Steering Rack: The FE2 Suspension Warning

Symptoms of a Failing Steering Rack

A failing steering rack on an Oldsmobile Intrigue can show several signs. It's important to distinguish these from other issues like a bad power steering pump or worn tie rods.

Noises: Clunks, Grinding, and Whining

• Clunking or Knocking: This is one of the most common symptoms. You may hear a distinct "clunk" or feel a knock through the steering wheel when turning at low speeds, like in a parking lot. This is often caused by worn internal gears or loose mounting bushings. On these GM W-body cars, a clunk can also come from a worn intermediate steering shaft, so diagnosis is key.
• Grinding: A grinding noise when turning can indicate metal-on-metal contact inside the rack, a sign of severe wear or damage. This might happen if the internal bearings have failed.
• Whining or Moaning: A whining sound that gets louder when you turn the wheel is often associated with low power steering fluid or a failing power steering pump. However, if the rack itself has a significant internal leak, it can cause the pump to work harder and whine.

Steering Feel and Response

• Loose or Vague Steering: If you feel excessive play or a "dead spot" in the steering wheel, it could be due to worn gears inside the rack. The car may feel like it wanders on the road.
• Stiff or Heavy Steering: A loss of power assist, making the wheel hard to turn, can be caused by a failing rack, especially if it happens intermittently or in one direction. This could be due to a bad internal seal or a problem with the pinion valve body.
• Pulling to One Side: While often an alignment issue, a faulty steering rack with a persistent internal leak or valve problem can cause the vehicle to pull.

Fluid Leaks

Power steering fluid leaks are a clear sign of a problem. On a steering rack, leaks typically occur from the end seals (wetness inside the rubber bellows/boots) or from the pinion tower where the steering shaft connects. The fluid is typically red or light brown. If you see black or dark brown fluid with a burnt smell or metallic particles, it indicates severe wear and contamination in the system.

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While there are no recalls specifically for the steering rack failing on the 1998-2002 Intrigue, there was a significant recall related to the power steering system on some 1998 models.

• NHTSA Recall 03V-527: This recall affected some 1998 Oldsmobile Intrigue models, among other GM vehicles. The issue involved a pinion shaft that could move, leading to increased steering effort or, in severe cases, high resistance to turning left followed by unintended power assist to the right. This was a serious safety issue that could lead to a crash.
• Intermediate Shaft Clunk: A common complaint on many GM vehicles of this era is a clunking noise from the intermediate steering shaft, which connects the steering column to the rack. This is often misdiagnosed as a faulty steering rack. The shaft's splines can bind and release, creating a clunk. Lubricating or replacing the intermediate shaft often solves this specific noise.
• Ignition Switch Recall (NHTSA 14V-400): While not a steering rack issue, a major recall for the ignition switch could cause the engine to turn off while driving, resulting in a sudden loss of power steering assist. This is a critical safety repair that should be verified as completed.

Buying a Used 1998-2002 Intrigue Steering Rack

A used OEM steering rack can be a cost-effective and reliable alternative to expensive new or sometimes questionable remanufactured parts. Here’s what to look for:

1. Verify the RPO Code: First and foremost, ensure the donor vehicle had the same suspension RPO code (e.g., FE2) as your car. If buying online, get the VIN of the donor car and check its options.
2. Inspect the Bellows Boots: The rubber boots at each end of the rack are critical. They must be intact, with no rips, tears, or cracks. A torn boot allows dirt and water in, which will quickly destroy the inner seals and cause leaks. If a boot is torn, assume the rack is bad.
3. Check for Leaks: Look for any signs of fluid leakage, especially around the pinion tower (where the steering shaft connects) and at the ends of the rack near the boots. Squeeze the boots; if they feel full of fluid, the inner seals have failed.
4. Examine the Lines and Fittings: Inspect the metal hydraulic lines that run across the rack. Ensure they are not heavily corroded, bent, or damaged. Check that the threaded fittings are clean and not stripped.
5. Inspect the Inner Tie Rods: The used rack should come with inner tie rods. Grab each one and try to move it up and down or in and out. There should be no free play or clunking; movement should be smooth but firm. While you'll likely replace the outer tie rods, good inner tie rods are a sign of a well-cared-for part.
6. Mileage Isn't Everything: A lower-mileage part is generally better, but condition is more important. A 150,000-mile rack with intact boots from a dry climate is a better bet than a 75,000-mile rack with torn boots from a state that uses heavy road salt.

Cost of Replacement

The cost to replace a steering rack can vary significantly based on the parts chosen and labor rates.

Related Parts to Inspect and Replace

When replacing the steering rack, it's wise to inspect and likely replace several related components.

• Outer Tie Rod Ends: These are almost always replaced with the rack. They are inexpensive and critical for proper alignment.
• Power Steering Hoses: Inspect the high-pressure and return hoses for leaks, swelling, or brittleness. It's much easier to replace them while the rack is out.
• Power Steering Fluid: The system must be completely flushed and refilled with the correct type of new, clean power steering fluid. Do not reuse old fluid.
• Intermediate Steering Shaft: As mentioned, this part can cause clunking noises. Inspect it for play at its U-joints and splines while you have access.

Installation Tips and Procedures

Replacing the steering rack on an Intrigue is a job for an experienced DIY mechanic or a professional. It typically involves lowering the rear of the engine subframe for access.

• Center the New Rack: Before installation, turn the new rack's input shaft from lock-to-lock, counting the total turns. Then, turn it back exactly half that amount. This centers the rack.
• Secure the Steering Wheel: Before disconnecting the steering shaft, make sure the steering wheel is centered and locked in place to avoid damaging the clockspring (airbag coil).
• Torque Specs: Always use a torque wrench for the rack mounting bolts and tie rod end nuts. Typical torque for rack mounting bolts is around 60-85 ft-lbs, but consult a service manual for exact specifications.
• Bleeding the System: After installation, the system must be bled of air. With the front wheels off the ground, fill the reservoir and, with the engine off, slowly turn the steering wheel from lock to lock several times. Then, start the engine and repeat, checking the fluid level until all whining stops and steering is smooth.
• Alignment is Mandatory: A professional four-wheel alignment is absolutely required after replacing a steering rack.
