What This Product Does:

• Isolate Vibration & Noise - They provide a cushioning interface between the rigid subframe and the softer body shell, helping absorb road vibrations, shock, and noise.
  
• Locate the Subframe Precisely - The bushings restrict movement of the subframe in certain directions, maintaining alignment and preventing unwanted shifts under load (acceleration, braking, cornering).
  
• Allow Controlled Flexibility - While they restrain gross motion, they permit some small movement / compliance to avoid excessive stress on the chassis or suspension components, especially as the car moves over bumps or under torque loads.
  
• Support Rear-End Stability & Handling - Because the subframe holds rear suspension geometry (arms, links, differential, etc.), worn or soft bushings allow variation in alignment under load, reducing precision and stability.
  
  

Symptoms & Signs Of Worn Or Failing Bushings:

• Clunks, knocks, or bangs from the rear over bumps, especially during acceleration or deceleration.
  
• Loose or imprecise handling / rear-end movement under cornering or sudden load change.
  
• Rear stability issues such as traction irregularities or feeling the car “wander” or “step out” when pushing hard.
  
• Poor alignment retention — alignment specs (camber, toe) may shift after driving or under load, requiring frequent re-adjustment.
  
• Vibration or harshness through the chassis, especially at the rear, more transmitted through the body.
  
• Visible deterioration like cracks, splits or deformation in the rubber, excessive flex / play when the car is raised, or separation between inner and outer portions of the bushing.
  
  

Why Replacement Matters:

• Restores rear-end precision — new bushings ensure the subframe is held firmly and accurately, improving handling and chassis response.
  
• Better alignment stability — new bushings keep suspension settings stable, reducing need for frequent alignment checks or changes.
