What is the solution for squeaking rear wheels when going over speed bumps?

The solution for squeaking rear wheels when going over speed bumps is: 1. Replace aging springs; 2. Inspect and repair the car's shock absorbers; 3. Inspect and repair the car tires; 4. Replace brake pads; 5. Secure the exhaust pipe. The functions of tires are: 1. Support the entire weight of the vehicle and bear the car's load; 2. Transmit traction and braking torque to ensure the adhesion between the wheels and the road surface. Tire maintenance methods include: 1. Regularly clean stones from tire treads; 2. Reduce exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Regularly inspect front wheel alignment.

I've been driving for decades and have encountered the issue of rear wheels squeaking over speed bumps several times. Last time my car had this problem, after inspection, it turned out to be due to aged and dry rubber bushings in the rear suspension, which caused friction and produced the squeaking sound. I tried using a silicone-based lubricant spray on the bushing connections, and the noise temporarily disappeared, but it came back after a while. Eventually, I went to a repair shop and spent some money to replace the bushings, which completely solved the problem. I suggest you first try lubricating the suspension parts yourself, perhaps with a product like WD-40. If the noise persists after lubrication, it might be due to a broken shock absorber or loose springs, in which case you should consult a professional mechanic. Don’t underestimate this noise—ignoring it for a long time could accelerate part wear and affect driving safety. It’s best to regularly inspect the suspension system to prevent such issues.

As a car enthusiast, I usually attribute rear wheel squeaking to issues in the suspension system. For instance, aging bushings losing lubrication or failed internal damping in shock absorbers can cause friction noises. You can try DIY solutions like spraying silicone oil to lubricate rubber components. If that doesn't work, consider replacing the bushings or even the entire shock absorber set. Don't forget to check tire pressure balance, as sometimes a simple adjustment can reduce friction noise. However, the safest approach is to have a skilled mechanic diagnose the issue, since the noise might involve bearings or brake components. Driving slowly over speed bumps can prolong suspension life and prevent frequent problems.

I just got my driver's license, and the squeaking noise from the rear wheels when going over speed bumps makes me nervous, fearing an accident. I asked an experienced mechanic, who said the most common cause is friction from rubber components like cracked bushings, which should be lubricated or replaced. I bought a can of lubricant and sprayed it on the rear suspension joints, which temporarily reduced the noise. Eventually, I went to the 4S shop for a check-up and replaced the parts, which finally made it quiet. I suggest you try simple lubrication first, and if that doesn't work, visit a professional shop as soon as possible. Don't ignore strange noises, as they might lead to bigger hidden dangers affecting safe driving. Checking the tightness of suspension screws weekly can also help.
