Vehicle Model Clarification
If you are searching for a suspension control arm bushing for a 1977, 1978, 1979, 1980, or 1981 Pontiac Tempest, it is important to know that this specific model was not manufactured in North America during those years. Production of the U.S. market Tempest nameplate ended in 1970. The name was succeeded by the Pontiac LeMans, which became Pontiac's primary intermediate-sized car. It's very likely you own a 1977-1981 Pontiac LeMans or Grand LeMans, as this was the vehicle that carried the Tempest's lineage forward on the GM A-body platform. The Tempest name was used again from 1987-1991, but only in Canada for a rebadged version of the Chevrolet Corsica, which is a completely different front-wheel-drive compact car.
Pro Tip: Before ordering parts, check the vehicle identification number (VIN) and the badging on your car. Your registration and title documents will confirm the exact model and year. This will ensure you search for parts for the correct vehicle, which is likely a Pontiac LeMans.
Suspension Control Arm Bushings for the 1977-1981 Pontiac LeMans
Since the 1977-1981 Tempest does not exist, this guide will refer to its successor, the Pontiac LeMans, for which parts are available. Control arm bushings are wear items and are critical for proper suspension geometry and ride quality. On these A-body cars, worn front upper and lower control arm bushings can cause a range of issues.
Symptoms of Failing Control Arm Bushings on a 1977-1981 Pontiac LeMans
- Clunking or Knocking Noises: A common symptom is a metallic clunking sound when going over bumps or during acceleration and braking. This is caused by excess movement in the control arm as the worn bushing allows metal-on-metal contact.
- Poor Steering Response: Worn bushings can create slack in the steering system, leading to a vague or wandering feeling. The steering wheel may feel loose or require constant correction to keep the car driving straight.
- Uneven Tire Wear: Failed bushings can alter the vehicle's alignment, specifically the camber and caster angles. This results in accelerated and uneven wear on the inner or outer edges of the front tires.
- Visible Damage: You may be able to see that the rubber is cracked, torn, or has separated from its metal sleeve. Sometimes, the bushing may be completely missing.
Choosing the Right Aftermarket Bushings
For a 1977-1981 Pontiac LeMans, new OEM (Original Equipment Manufacturer) bushings are no longer available. The repair market relies entirely on aftermarket parts. These are typically available in two materials:
- Standard Rubber: These bushings are designed to replicate the original part's performance and ride quality. They offer good vibration absorption for a comfortable ride and are the most affordable option.
- Polyurethane: These are a performance upgrade. Polyurethane is a firmer material that deflects less than rubber, resulting in more precise handling and better suspension feedback. However, they can transmit more road noise and vibration into the cabin. Brands like Energy Suspension offer polyurethane kits for related GM A-body cars.
Known Issues, Recalls, and TSBs
There are no recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for suspension control arm bushings on a 1977-1981 Pontiac Tempest, as the vehicle does not exist. A search for the corresponding Pontiac LeMans from the same period also shows no recalls for this specific component.
Frequently Asked Questions (FAQ)
Why can't I find parts for my 1978 Pontiac Tempest?
Parts are not listed because the Pontiac Tempest was not made in 1978. The model you likely have is a Pontiac LeMans. Search for parts using that model name for the 1977-1981 year range.
What was the difference between the Tempest and the LeMans?
In the 1960s, the LeMans was a high-end trim level of the Tempest. After 1970, Pontiac retired the Tempest name and used LeMans for its entire mid-size lineup. By 1977, the LeMans was the established model.
Are aftermarket control arm bushings for a Pontiac LeMans a good choice?
Yes. Since original GM parts are no longer produced, quality aftermarket brands are the standard for these repairs. They provide a reliable and affordable solution to restore your vehicle's handling and ride quality.
Can I replace just the bushings, or do I need the whole control arm?
For these vehicles, bushings are available separately. Replacing only the bushings is more labor-intensive as it requires a press to remove the old ones and install the new ones. Some mechanics may prefer to replace the entire control arm if it comes with new bushings and a ball joint pre-installed, saving time and addressing multiple wear points at once.
