A Deep Dive into Suspension Control Arm Bushings for the 1981-1986 Buick Skylark
Fix clunks, wandering steering, and poor handling by understanding and choosing the right control arm bushings for your classic Skylark.
- For a factory ride, choose standard rubber bushings from brands like Moog or Delphi; for performance handling and a much stiffer ride, choose polyurethane from a brand like Nolathane.
- This is not a simple DIY job; it requires a bushing press tool to remove the old parts and install the new ones without causing damage.
- Always replace control arm bushings in pairs (left and right) to ensure balanced handling and predictable steering.
- A full wheel alignment from a professional shop is required immediately after replacement to prevent unsafe handling and premature tire wear.
Signs of Failing Control Arm Bushings
Worn control arm bushings on your Skylark will make the car feel less stable and predictable. Because they fail gradually, you might not notice the change until symptoms become severe. Pay attention to these common signs:
🎬 Watch: 7 common symptoms of bad control arms and bushings.- Clunking or Knocking Noises: This is the most frequent symptom. You may hear clunking sounds from the front end, especially when driving over bumps, braking, or making sharp turns. This noise is often the sound of metal-on-metal contact as the worn bushing allows for excessive movement.
- Steering Wander or Pulling: Your car may feel like it's wandering on the road, requiring constant small steering corrections to keep it straight. It might also pull to one side during acceleration or braking.
- Uneven Tire Wear: Worn bushings can throw off the wheel alignment. Inspect your front tires for excessive wear on the inner or outer edges, which is a classic sign of a bad bushing.
- Vibrations: You might feel vibrations through the steering wheel, especially at higher speeds. This happens because the worn bushings can no longer effectively dampen road harshness.
A Note on the GM X-Body Platform
Your 1981-1986 Skylark is built on the General Motors X-body platform. These vehicles were known for numerous issues when new, including some related to suspension and braking. While no specific recalls were found for the control arm bushings on your Skylark, a major GM recall for failing rear suspension bolts did occur in 1981, though sources suggest it did not apply to the X-body. Given the age and history of the vehicle, paying close attention to suspension components is crucial for safety.
Choosing the Right Aftermarket Bushing
Original equipment (OEM) bushings for a vehicle of this age are no longer available. The aftermarket is your only source for new parts, offering a range of quality and material types. The main choice you will make is between standard rubber and performance polyurethane bushings.
Standard Replacement (Rubber)
These bushings are designed to restore the original ride quality and feel of your Skylark. They are the best choice for daily drivers and owners who prioritize comfort over performance.
- Delphi: Often considered an OE-equivalent brand, Delphi parts are known for quality and reliability that meets or exceeds original factory standards. They are a dependable choice for a standard replacement.
- Moog: Moog is a premium aftermarket brand, often chosen by professional mechanics. They are known for their "Problem Solver" line, which frequently features designs that improve on the original part's weaknesses.
- Mevotech: Generally seen as a mid-tier brand that offers a good balance of affordability and quality. While some users are happy with the performance for the price, others have reported mixed results on longevity.
Performance Upgrade (Polyurethane)
Polyurethane is a much stiffer material than rubber. Choosing this type of bushing is a performance upgrade, not a standard replacement. It will noticeably change how your car drives.
Rubber vs. Polyurethane:
Choose Rubber if: You want to maintain the original, comfortable ride your Skylark was designed for.
Choose Polyurethane if: You want sharper steering response and better handling for performance driving, and you don't mind a much firmer ride with more road noise.
- Nolathane: This is a well-known brand specializing in polyurethane bushings. These parts will provide a significant increase in handling, stability, and steering feedback. However, this comes at the cost of ride comfort. The stiffer material transmits more noise and vibration into the cabin and can make the ride feel harsh, which may not be ideal for a daily driven classic car.
| Part | Typical Price Range (Per Bushing) |
|---|---|
| Suspension Control Arm Bushing | $10.79 - $34.32 |
Note: Prices are estimates and can vary by brand and retailer. Your Skylark has multiple bushings in the front control arms (upper and lower), so be sure to order the correct quantity for your repair. 🎬 See how to install a lower control arm bushing.
Frequently Asked Questions (FAQ)
Can I replace just the bushings, or do I need a whole new control arm?
For the 1981-1986 Skylark, replacing just the bushings is the standard and most cost-effective repair. Unlike many modern cars where the ball joint is integrated, on your vehicle the bushings can be serviced separately.
Is replacing control arm bushings a DIY job?
This is a difficult job for a beginner. While removing the control arm is straightforward, the old bushings must be pressed out and the new ones pressed in using a special tool like a hydraulic press or a large C-clamp style bushing press. Without the right tool, you can damage the control arm or the new bushing. If you are not an experienced mechanic with these tools, this job is best left to a professional shop.
🎬 Watch this guide on how to replace control arm bushings.Should I replace bushings on both sides at the same time?
Yes. Bushings wear out from age and use, so if one side has failed, the other side is likely not far behind. Replacing them in pairs (both front left and front right) ensures balanced handling and prevents you from having to do the same job twice.
Do I need a wheel alignment after replacing the bushings?
Yes, a four-wheel alignment is absolutely necessary after replacing control arm bushings. The new parts will change the suspension geometry, and an alignment is required to ensure proper handling and prevent rapid tire wear.
