* Rear Shocks/Dampers: While you mentioned struts (front suspension), the rear suspension likely uses shocks or dampers. Worn or faulty rear shocks can cause a wobbly feeling, especially at lower speeds. They dampen the up and down movement, and if they're bad, that movement can translate into a wobble.
* Rear Suspension Components: Several other parts in the rear suspension could be the culprit:
* Wheel bearings: Worn wheel bearings can create a wobble or vibration.
* Control arm bushings: Worn or damaged bushings allow excessive movement in the suspension, leading to instability.
* Trailing arms (or other rear suspension linkages): Damage or wear in these components can cause instability.
* Axle: A bent or damaged axle can cause wobbling.
* Driveshaft: If your car is rear-wheel drive, a worn or damaged driveshaft could be contributing to the problem. A universal joint issue within the driveshaft is a possibility.
* Tire Balance/Alignment (Rear): Even though you had the tires checked, ensure they are properly balanced and aligned in the rear. A slight imbalance or misalignment can be more noticeable at lower speeds.
* Brake components: A sticking brake caliper or warped rotor could also induce a wobble, especially at lower speeds.
What to do next:
1. Return to a mechanic: Explain the issue *specifically* mentioning that the problem persists even after strut replacement and tire checks. They need to know the speed range where it happens.
2. Thorough inspection: Request a thorough inspection of the *rear* suspension components, including shocks/dampers, wheel bearings, control arm bushings, trailing arms (or equivalent linkages for your car's model), and the driveshaft (if applicable). Mention the possibility of a brake issue.
3. Road test with a mechanic: This will allow the mechanic to experience the wobble firsthand.
Don't continue driving the car if the wobble is significant, as it could be unsafe. Addressing the root cause is crucial for your safety and to prevent further damage.
