Suspension Control Arm Bushing Guide for the 1995-2000 Cadillac DeVille
Hearing clunks and rattles from your front end? Your control arm bushings are the likely cause.
- A clunking noise over bumps is the most common symptom of failed control arm bushings on this DeVille.
- For a quiet, comfortable ride true to the Cadillac name, choose a quality aftermarket rubber bushing; avoid hard polyurethane bushings.
- It is often easier and more cost-effective to replace the entire control arm assembly rather than just pressing in new bushings.
- A wheel alignment is mandatory after this repair to prevent unsafe handling and premature tire wear.
Is Your DeVille's Smooth Ride Ruined by Noise?
If you're hearing a clunking, rattling, or popping sound from the front of your 1995-2000 DeVille, especially when driving over bumps, you're not alone. These rubber bushings dry out, crack, and collapse over time. This leaves extra space, allowing the metal control arm to knock against its mounting points. This metal-on-metal contact is the source of the noise and a clear sign that your bushings have failed.
Known Issues for 1995-2000 Cadillac DeVille
TSB for Front-End Noise: General Motors issued a Technical Service Bulletin (TSB #990308005) for the 1998 DeVille for a "clunk, rattle or metal to metal noise from front of vehicle." This issue is common across the entire 1994-2000 generation due to the shared suspension design.
NHTSA Recall on Suspension Mounts: There is a critical safety recall for 1995 models (NHTSA Recall No. 98V115) concerning front suspension support brackets. These brackets can fracture, leading to a failure of the lower suspension mounting and a potential loss of vehicle control. It is crucial to have a professional check if this recall work has been performed on your vehicle.
Choosing the Right Aftermarket Bushing Kit
For a vehicle of this age, aftermarket parts are a practical choice. The original bushings were designed for comfort, and the goal with a replacement should be to restore that quality without paying high dealer prices for parts that may be discontinued. Here’s how the available brands stack up for your DeVille:
- Dorman (Standard Replacement): Dorman is a common, budget-friendly option that provides a factory-style rubber bushing. It's designed to restore original performance and is a suitable choice for daily driving. However, some users in forums report that the rubber may not be as durable as the original, potentially leading to a shorter lifespan.
- Mevotech (Tiered Options): Mevotech often offers multiple quality levels, such as "Original Grade" and "Supreme". The Supreme line is generally considered a good quality replacement, while the base grade is a budget part. Like Dorman, experiences can be mixed, with some users reporting premature wear. If choosing Mevotech, aim for their higher-tier offerings.
- Nolathane (Polyurethane - Not Recommended for Comfort): Nolathane specializes in polyurethane bushings, which are a much harder material than rubber. This improves handling response and durability but comes at a significant cost to ride quality, transmitting more noise and vibration into the cabin. For a Cadillac DeVille, where a smooth, quiet ride is the primary goal, polyurethane bushings are generally not recommended.
Pro Tip: For this specific repair, it is often more time- and cost-effective to replace the entire control arm assembly, which comes with new bushings and a new ball joint already installed. The labor to press old bushings out and new ones in can often exceed the cost of a complete new arm.

Frequently Asked Questions
Do I need an alignment after replacing the bushings?
Yes, absolutely. Replacing control arm bushings or the entire control arm will change your vehicle's suspension geometry. A four-wheel alignment is mandatory to ensure your DeVille drives straight, handles properly, and doesn't cause rapid, uneven tire wear.
Can I just replace the bushings on one side?
While you can, it is highly recommended to replace them in pairs (both front left and front right). If one bushing has failed due to age and wear, the other side is likely not far behind. Replacing both at once ensures balanced handling and prevents you from having to do the same job again soon.
Is a clunking noise always from the control arm bushings?
Not always, but they are a very common cause on these DeVilles. Other parts that can make similar noises include worn sway bar links, bad ball joints, or failing strut mounts. A thorough inspection is the best way to pinpoint the exact source of the noise.
Should I get rubber or polyurethane bushings for my DeVille?
Stick with high-quality rubber bushings. The 1995-2000 Cadillac DeVille was engineered for a quiet, comfortable ride. Polyurethane is a stiff, performance-oriented material that will make the ride harsher and introduce more road noise, defeating the purpose of driving a Cadillac.
Technical Specifications
The 1995-2000 Cadillac DeVille uses a front suspension with upper and lower control arms. The bushings are made of a rubber compound designed to absorb vibration and maintain a quiet ride. Aftermarket options are available in both rubber and polyurethane, with rubber being the recommended material for this vehicle.
