Suspension noises like clunking or squeaking can indicate worn-out components, such as shocks, struts, or bushings. Harshness in the ride might also point to suspension problems. Regular inspections and timely replacements of worn parts are important for ensuring proper handling and ride comfort. We found that worn suspension components will gradually impact tire wear as well.

4.2. Steering Problems and Difficulty

Steering problems can range from minor issues, such as difficulty turning the wheel, to more serious concerns like power steering failure. Check the power steering fluid level and inspect the power steering pump. If you notice excessive play in the steering wheel or unusual noises, have the system inspected immediately to prevent further damage. We often find that alignment issues also affect steering.

4.3. Tire Wear and Alignment

Regular wheel alignment is vital to prevent uneven tire wear. If the alignment is off, it can lead to premature tire wear and affect the vehicle's handling. Regular tire inspections and wheel alignments, as per the manufacturer's recommendations, can help maintain the vehicle's handling and safety.
