Why Your Car Shakes Weird Next to a Curb (Causes & Fixes)

Unusual shaking when driving near a curb often indicates wheel, tire, or suspension damage from impact with the curb or related imbalance issues.

Potential Causes

Bent Wheel or Rim High Probability

Hitting a curb can deform the wheel, causing imbalance and vibration at low speeds next to curb impact.

Tire Damage (Bulge/Flat Spot) High Probability

Curb impact may cause internal tire damage or flat spots, leading to shaking when the tire rotates.

Suspension Component Damage Medium Probability

Strut, control arm, or tie rod damage from a curb hit leads to uneven motion and shaking next to curb.

Wheel Alignment Out of Spec Medium Probability

Alignment issues from curb impact cause vibration and steering pull.

Diagnostic Steps

Visual Wheel and Tire Inspection

Check wheels and tires for visible bends, bulges, or damage from curb impact.
Check Wheel Balance and Alignment

Have a shop check tire balance and perform wheel alignment to detect imbalance or misalignment caused by hitting curb.
Inspect Suspension Components

Examine struts, control arms, tie rods for bends or play caused by impact.

DIY Fixes

Check and Adjust Tire Pressure Beginner

Estimated Cost: $0 - $10

Replace Damaged Wheel or Tire Intermediate

Estimated Cost: $100 - $400

OBD-II Live Data Analysis

Use a scan tool to monitor these parameters. Comparing live values against the normal range can help identify the root cause.

PID

Steering Angle Sensor

Normal Range Near zero at straight

Abnormal Condition Sudden changes when straight

Technical Insight: Indicates sensor or mechanical misalignment after impact

PID

Wheel Speed Sensor

Normal Range Consistent speed per wheel

Abnormal Condition Erratic wheel speed on one side

Technical Insight: Suggests damaged sensor or wheel causing vibration

Frequently Asked Questions

Why does my car shake when I drive next to the curb?

Your car may shake next to the curb due to potential issues with the suspension or steering system, such as a bent wheel, tire damage, or suspension component damage caused by hitting the curb.

What should I check if my car shakes after hitting a curb?

Inspect your wheels and tires for visible bends, bulges, or damage. Additionally, have a professional check the tire balance and perform a wheel alignment to identify any imbalances or misalignments.

Can I fix my car shaking next to the curb myself?

You can start by checking and adjusting the tire pressure. If you find any damaged wheels or tires, you may need to replace them. However, for suspension issues, it's best to consult a professional mechanic.

What are the signs of tire damage that could cause my car to shake?

Look for visible bulges, flat spots, or uneven wear on your tires. These can indicate damage that may lead to shaking, especially after hitting a curb.

How can I tell if my suspension components are damaged?

Examine your struts, control arms, and tie rods for any bends or play. If you notice any irregularities, it's advisable to have a professional inspect your suspension system.
