Buick Centurion Control Arm Bushings

Buick Centurion Control arm bushings

Control arm bushings for your Buick Centurion start at low prices, and AutoBuffy stocks multiple options from brands including top OE-quality brands. These rubber or polyurethane sleeves isolate the control arm from the subframe, absorbing road shock and keeping your wheel geometry stable. When they crack or collapse, handling becomes imprecise and metal-on-metal contact accelerates wear on surrounding components.

Signs your Buick Centurion needs new control arm bushings

  • Clunking or knocking noise from the front suspension when going over bumps, potholes, or during braking
  • Steering feels vague or loose, requiring constant small corrections to hold a straight line
  • Uneven or rapid tire wear, particularly feathering or wear on one edge of the tread
  • Vibration through the steering wheel or floor at highway speeds that worsens over rough pavement
  • Vehicle pulls to one side during braking as the control arm shifts under load
  • Visible cracking, tearing, or separation of the rubber bushing material when inspected at the wheel well

Which control arm bushings should you buy for your Buick Centurion?

The main decisions are material — rubber vs. polyurethane — and whether you're buying an individual bushing or a complete control arm with bushings pre-installed. Position also matters: front lower control arms typically take more load than upper or rear arms, so material choice should reflect how the Buick Centurion is used.

OE-spec rubber bushing
Best for
Daily drivers wanting a quiet, factory-like ride
What you get
Matched compliance and NVH damping; easiest press-fit installation; typically the most affordable replacement
Polyurethane bushing
Best for
Performance driving, towing, or vehicles with repeated bushing failures
What you get
Firmer, longer-lasting material that resists oil and heat; improved handling precision; slight increase in road noise and harshness
Pre-assembled control arm with bushings
Best for
High-mileage Buick Centurions or when the arm itself is bent or worn
What you get
New arm and bushings as a unit; eliminates the need for a press; recommended when bushing replacement alone won't restore geometry
Heavy-duty or greaseable bushing
Best for
Off-road use or Buick Centurions in high-corrosion climates
What you get
Reinforced design with a zerk fitting for periodic lubrication; extends service life in harsh conditions; often polyurethane or metal-sleeve construction

After safely lifting and supporting the Buick Centurion, remove the wheel and disconnect the control arm bolts, noting the orientation of any eccentric alignment bolts before removal. Use a bushing press or C-clamp press kit to drive out the old bushing and press in the replacement, ensuring it is fully seated and square in the housing. Reassemble with the suspension at ride height before final torquing of the arm bolts, then schedule a wheel alignment before returning the Buick Centurion to normal use.

Frequently asked questions

How much does it cost to replace control arm bushings on a Buick Centurion?
Parts alone start at low prices for a single bushing on a Buick Centurion. If a shop presses in new bushings, labor typically adds one to two hours of shop time. Replacing a complete pre-assembled control arm costs more upfront but can save on labor. A four-wheel alignment is usually required afterward and is an additional cost.
Can I drive my Buick Centurion with worn control arm bushings?
You can drive short distances, but it is not safe to ignore worn control arm bushings for long. Deteriorated bushings cause unpredictable handling, pull under braking, and accelerated tire wear. As the bushing collapses further, the control arm can shift enough to affect wheel alignment severely or, in extreme cases, contact adjacent metal components.
Do I need to replace control arm bushings in pairs on my Buick Centurion?
Replacing both sides at the same time is strongly recommended. Bushings on both sides of the Buick Centurion age at the same rate, so if one has failed the other is usually close behind. Replacing only one side can create an imbalance in suspension compliance, leading to a pull or uneven handling feel.
Do I need an alignment after replacing control arm bushings on a Buick Centurion?
Yes — a four-wheel alignment is required after replacing control arm bushings on a Buick Centurion. The control arm sets camber and caster angles, and even a well-executed bushing replacement can shift those values slightly. Skipping the alignment leads to premature tire wear and handling that does not match the vehicle's specification.
How long do control arm bushings last on a Buick Centurion?
OE-spec rubber bushings typically last anywhere from 50,000 to 100,000 miles, though this varies widely by road conditions, climate, and driving style. Vehicles frequently driven on rough roads or in areas with road salt tend to see earlier bushing degradation. Polyurethane replacements generally outlast rubber but are not immune to wear over time.
Can I replace control arm bushings myself on a Buick Centurion?
It is possible for a mechanically experienced DIYer, but pressing out and pressing in bushings requires a hydraulic press or a heavy-duty bushing press kit. Without the right tooling, the bushing sleeve can be damaged during removal. Choosing a pre-assembled control arm eliminates the press requirement and makes the job more approachable with common hand tools.
