Oldsmobile Intrigue Rear Lateral Arm Guide (1998-2002)
Fix the clunking noises and sloppy handling from your Intrigue's rear suspension.
- A clunking rear end and uneven tire wear are the most common signs of a bad lateral arm on your Intrigue.
- You must get a wheel alignment after replacement to prevent destroying your tires.
- The Intrigue has a forward and a rearward lateral arm on each side; ensure you order the correct one.
- For this vehicle, budget-friendly aftermarket brands like Dorman and Mevotech are a practical and effective solution.
Is Your Intrigue Making Noise? Signs of a Bad Lateral Arm
When the original lateral arms on your Oldsmobile Intrigue fail, it's almost always due to the rubber bushings at each end. Over time, these bushings dry out, crack, and wear away. This allows for metal-on-metal contact and excessive movement, leading to several common symptoms.
- Clunking or Rattling Noises: The most common complaint is a clunking or rattling sound from the rear of the car, especially when driving over bumps, potholes, or uneven roads. This is the sound of the loose arm moving around.
- Loose or Wandering Rear End: Your car might feel unstable, especially at higher speeds or during turns. It may feel like the rear of the car is 'steering' itself or wandering from side to side.
- Uneven Rear Tire Wear: A worn lateral arm allows the wheel's alignment (specifically the toe and camber) to change as you drive. This will cause the inside or outside edge of your rear tires to wear out much faster than normal.
Choosing the Right Aftermarket Lateral Arm
For a vehicle like the 1998-2002 Intrigue, new OEM parts from a dealer are likely expensive or discontinued. Aftermarket parts are the most practical and affordable solution. The main brands you will find are Dorman and Mevotech.
Both Dorman and Mevotech are well-known aftermarket brands that offer cost-effective replacement parts. They are generally considered budget-friendly options suitable for daily driving. While some professional mechanics prefer premium brands, for this specific vehicle, either Dorman or Mevotech will restore the original performance and solve your clunking issues. There is no significant performance difference between these two brands for this application; choosing the one with the better price or availability is a sound decision.
Pro Tip: Common Ordering Mistake
The Intrigue uses two different lateral arms per side in the rear: a forward and a rearward arm. They are not interchangeable. Before ordering, inspect your vehicle to see which one has failed, or simply plan to replace both for a complete repair. Always double-check the part's position in the product description before purchasing.
Cost of Replacing an Oldsmobile Intrigue Lateral Arm
The cost to replace a lateral arm is very reasonable, especially if you can do the work yourself. The parts themselves are inexpensive.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Lateral Arm (Dorman, Mevotech) | $39 - $53 per arm |
| Shop Labor | $150 - $250 |
| Total Professional Replacement (One Side) | $190 - $300 |
| Wheel Alignment (Required) | $80 - $150 |
Frequently Asked Questions (FAQ)
Can I replace just one lateral arm?
Yes, you can replace only the single arm that has failed. However, the arms on both sides of the car have experienced the same amount of wear. If one has failed, the other is likely not far behind. For balanced handling and peace of mind, it is often recommended to replace them in pairs (e.g., both rearward arms at the same time).
Is this a difficult job to do myself?
For an experienced DIY mechanic, this is a manageable job. It requires safely lifting and supporting the vehicle, and then removing two bolts per arm. The biggest challenge can be rusted or seized bolts. A long breaker bar and plenty of penetrating oil are your best friends for this job. If you are not comfortable working under your car, it's best to leave this to a professional.
Do I need any special tools?
No highly specialized tools are required. You will need a good socket set with a breaker bar, a torque wrench to tighten the bolts to specification, jack stands to safely support the vehicle, and a wheel chock. A can of penetrating rust inhibitor (like PB Blaster) is also highly recommended to help loosen old, rusty bolts.
What are the torque specs for the lateral arm bolts?
Always refer to a vehicle-specific repair manual for the exact torque specifications. However, a common torque spec for GM W-body cars of this era is around 70-80 ft-lbs for the main bolts. It is critical to tighten bolts while the suspension is at its normal ride height (with the weight of the car on it) to avoid premature bushing failure.
