Tires
Wheels
- Balancing tires and tire alignmentare erroneously considered to be the same thing. Whereas balancing the tires has to do with their geometry on the rim, tire alignment has to do with the angle of the wheel itself. Misaligned wheels wear down tires more quickly, cause reduced stability and control, and finally rattling or vibrations you’re experiencing. Wheel alignment is a task for a …
Brakes
- Car brakes rely on friction to stop the vehicle. When you press on the brake pedal, a hydraulic pump pushes oil towards the caliper, where a caliper piston compresses brake pads against the disc. Try to listen for a sound that accompanies the vibrations. It usually happens right after you’ve pressed the brake, and especially in the 30 to 40 mph zone as you decelerate from higher …
Suspension
- Suspension is composed of many parts that work together to absorb the bumps and imperfections on the road. It’s also responsible for handling and stability of the vehicle. When one or more components fail, vibrations at 40 mph become common.
Engine & Transmission
- Problems with the powertrain of the vehicle can cause vibrations at 30, 40 mph & 60 mph, but the difficult part is to identify them at home. Some are easier to check than others, so I’ll take you in order of severity to rule out suspects one by one.
