1979-1988 Buick Regal Suspension Control Arm Bushing Guide
Restore your Regal's classic ride and handling by replacing worn control arm bushings.
- Failing bushings on your Regal will cause clunking noises, loose steering, and uneven tire wear.
- Choose standard rubber bushings (ACDelco, Dorman) for a factory ride or polyurethane (Nolathane) for improved performance and durability.
- Replacement is a difficult DIY job that requires a hydraulic press or a loaner tool from a parts store.
- A full wheel alignment is mandatory after replacing control arm bushings to prevent tire damage and ensure safety.
Signs of Worn Control Arm Bushings
The original rubber bushings on your Regal can degrade over decades of use. When they fail, you'll notice a significant change in how your car drives. Common symptoms include:
- Clunking or Popping Noises: You may hear sharp noises from the front suspension, especially when going over bumps, braking, or making sharp turns. This is often caused by metal-on-metal contact as the worn bushing allows for excessive movement.
- Loose or Vague Steering: The steering may feel imprecise, requiring constant small corrections to keep the car straight. This is a sign that the worn bushings are allowing the control arms to shift, affecting alignment.
- Uneven Tire Wear: Bad bushings can cause the wheels to fall out of alignment, leading to accelerated wear on the inside or outside edges of your tires.
- Vibrations: You might feel vibrations through the steering wheel or the floor, particularly at higher speeds. This happens because the bushings can no longer effectively dampen road harshness.
Known Issues & Recalls
There was a recall issued on April 14, 1988, for 194 units of the 1988 Buick Regal concerning the lower control arm to ball joint attachment, which could become loose and cause a loss of steering control. The correction involved replacing both lower control arms. While this recall is very old, it highlights the importance of ensuring all suspension components are securely fastened. No other widespread recalls or Technical Service Bulletins (TSBs) specifically for control arm bushings on the 1979-1988 models were found.
Choosing the Right Aftermarket Bushing
When replacing your Regal's control arm bushings, you have a choice between standard rubber and performance-oriented polyurethane. The original factory arms are generally considered high quality, so replacing just the bushings is a common and effective repair.
Brand & Material Tiers
Good (Standard Replacement):
- Dorman: A widely available and affordable option. Dorman provides a direct, OE-style rubber replacement that is suitable for daily driving and restoring the original ride quality. They are often preferred by DIY mechanics for their ease of installation and guaranteed fit.
- Mevotech (Supreme): Mevotech's Supreme series offers a good balance of quality and affordability. These are durable rubber and steel replacements designed to withstand harsh conditions.
Better (OEM-Quality):
- ACDelco (Professional): As a GM-affiliated brand, ACDelco parts are often considered the closest you can get to original equipment quality. Choosing their Professional line ensures a fit and feel that is very similar to how your Regal drove from the factory.
Best (Performance/Heavy-Duty):
- Nolathane (Polyurethane): If you want to improve handling and steering response, polyurethane is the way to go. Nolathane bushings are much stiffer than rubber, which reduces control arm deflection and helps maintain alignment during aggressive driving. The trade-off can be a firmer ride and a potential for squeaking if not lubricated properly during installation.
Pro Tip: Rubber vs. Polyurethane
For a classic cruiser, standard rubber bushings from brands like ACDelco or Dorman will provide the most comfortable ride. For a performance-oriented build (like a Grand National or T-Type clone) or a car that will see track use, the improved handling from Nolathane polyurethane bushings is a significant upgrade. Polyurethane is also more durable than rubber.
| Part Type | Typical Cost (Per Bushing/Kit) |
|---|---|
| New Aftermarket (Rubber - Dorman, Mevotech) | $13 - $25 |
| New Aftermarket (OEM-Quality - ACDelco) | $20 - $35 |
| New Aftermarket (Polyurethane - Nolathane) | $25 - $40 |
| Shop Labor for Installation | $200 - $400 per axle |
Frequently Asked Questions
Should I replace the whole control arm or just the bushings?
For the 1979-1988 Regal, the original control arms are robust. If they are not bent or rusted, simply pressing out the old bushings and installing new ones is a cost-effective and reliable repair. However, replacing the entire arm (if available) can save significant labor time, as pressing bushings can be very difficult.
Do I need special tools to replace control arm bushings?
Yes, this job typically requires a hydraulic press or a specialized ball joint/bushing press tool to remove the old bushings and install the new ones without causing damage. Many auto parts stores offer these press tools as part of a free loaner program. You will also need standard mechanic's tools, a jack, and jack stands.
How many bushings does my Buick Regal have?
A typical 1979-1988 Buick Regal has a total of eight front control arm bushings: two on each of the two upper control arms, and two on each of the two lower control arms. The rear suspension has a similar setup. Always confirm the exact number and position for your specific vehicle before ordering.
Do I need a wheel alignment after replacing the bushings?
Yes. Replacing control arm bushings will absolutely affect your vehicle's wheel alignment. It is critical to have a professional four-wheel alignment performed immediately after the repair to ensure proper handling, safety, and to prevent rapid tire wear.
Technical Specifications
The 1979-1988 Buick Regal is part of the GM G-Body platform. Bushings are specific to upper or lower control arms and front or rear suspension. Polyurethane options often come in different hardness ratings.
