Buick Century Engine Torque Strut Bushings

Buick Century Engine torque strut bushings

Starting at $5.95, AutoBuffy stocks 1 engine torque strut bushings from DEA for the Buick Century. The torque strut bushing cushions the mount that controls engine movement during acceleration and braking. When it wears out, the engine rocks excessively in the bay, sending vibration and clunking into the cabin and stressing nearby drivetrain components.

Signs your Buick Century needs a new engine torque strut bushing

  • Loud clunk or thud from the engine bay during hard acceleration or sudden braking
  • Noticeable engine lurch or rocking when shifting from Park into Drive or Reverse
  • Vibration felt through the steering wheel, floor, or seat at idle and low speeds
  • Increased noise over speed bumps or dips as the engine shifts against worn rubber
  • Visible cracking, splitting, or collapse of the bushing rubber on inspection
  • Accelerated wear on CV axle boots or other drivetrain components from excess engine movement

Which engine torque strut bushing should you buy for your Buick Century?

The main decision is whether to replace just the bushing insert or buy a complete torque strut assembly, and whether to choose OE-spec rubber or an upgraded polyurethane compound. If the strut bracket itself is undamaged, a bushing-only replacement is the most cost-effective route; if the bracket is cracked or corroded, a full assembly saves labor.

OE-spec rubber bushing (insert only)
Best for
Daily drivers wanting factory ride quality and NVH isolation
What you get
Stock durometer rubber that matches original compliance and noise absorption
Polyurethane bushing (insert only)
Best for
Drivers who want reduced engine movement and longer bushing life
What you get
Firmer compound that resists oil and heat better than rubber; slightly more cabin vibration
Complete torque strut assembly (bushing pre-installed)
Best for
High-mileage vehicles with a worn or damaged bracket
What you get
New bracket and bushing as a unit — bolt-on installation, no pressing required
Performance/adjustable torque strut
Best for
Modified engines or track-use vehicles with elevated torque output
What you get
Reinforced bracket with solid or high-durometer bushing to tightly control engine movement under high load

Replacing the engine torque strut bushing on a Buick Century

Moderate⏱ 1–2 hoursSocket set and ratchetBreaker bar or impact wrenchHydraulic press with bushing drivers (if replacing insert only)Jack and jack standsPenetrating oil for corroded fasteners

Support the engine slightly with a jack and block to relieve load on the strut, then unbolt the torque strut from its mounting points on the engine bracket and chassis. If swapping the bushing insert only, press out the old bushing and press in the new one using correctly sized drivers to avoid damaging the bracket bore. Reinstall the strut, torque all fasteners to the manufacturer's specification for the Buick Century, and test by cycling through drive and reverse to confirm movement is eliminated.

Frequently asked questions

How much does it cost to replace engine torque strut bushings on a Buick Century?
Parts start at $5.95 on AutoBuffy. A bushing-only replacement is the least expensive route if the bracket is intact. Add shop labor of one to two hours if you're not doing it yourself. A complete strut assembly costs more upfront but typically reduces total labor time and eliminates the need for a hydraulic press.
Can I drive my Buick Century with a bad engine torque strut bushing?
You can drive short distances, but it is not advisable. A failed bushing allows the engine to move excessively, which puts stress on CV axles, coolant hoses, and wiring harnesses connected to the engine. Continued driving risks secondary damage that is significantly more expensive to repair than the bushing itself.
How long does an engine torque strut bushing last on a Buick Century?
OE rubber bushings typically last somewhere between 60,000 and 150,000 miles depending on driving style, climate, and exposure to oil or road chemicals. Aggressive stop-and-go driving and frequent hard acceleration shorten bushing life. Polyurethane replacements generally outlast rubber, though they transmit slightly more vibration into the cabin.
Do I need a hydraulic press to replace the bushing on a Buick Century?
If replacing the bushing insert only, yes — most factory bushings are pressed into the strut bracket and require a hydraulic or bench press and appropriate-sized drivers to remove and install correctly. Choosing a complete pre-assembled torque strut eliminates this requirement, making the job doable with basic hand tools and no press.
Is the engine torque strut bushing the same as the engine mount on a Buick Century?
They are related but different. Engine mounts support the engine's weight. The torque strut and its bushing specifically limit fore-and-aft engine rotation under acceleration and braking loads. A vehicle typically has both, and either can fail independently. Symptoms overlap, so inspect both when diagnosing engine movement or clunking noises.
How do I confirm the torque strut bushing is the source of the clunk on my Buick Century?
With the engine off, have an assistant apply the brakes firmly and shift between Drive and Reverse while you watch the engine bay safely from the side. Visible engine rocking or movement at the strut bracket confirms the bushing is worn. You can also grab the strut and check for play or see cracked rubber on direct inspection.
