What Causes the Shaking at Low Speeds of 30 to 40 mph?

[DeViolet]

Low-speed shaking between 30 to 40 mph can be attributed to the following reasons: 1. If the car shakes within a specific speed range, it might be due to wheel imbalance or resonance-induced vibrations. It is recommended that car owners visit a 4S shop for inspection and repair. 2. Low-speed shaking in cars is often caused by irregular wear of the clutch three-piece set (flywheel, clutch disc, and pressure plate), leading to misalignment of one or several components. 3. During the engagement process, if the clutch disc fails to engage smoothly but instead engages and disengages intermittently, the engine power starts to transmit and then suddenly slips, resulting in a jerky feeling similar to hopping. The solution is to replace the damaged components in the clutch three-piece set.
