Rear wheel noise in the Envision can be caused by the following reasons: Grit Friction: While driving, tiny grit particles may get between the brake pads and rotors, sometimes causing noise due to friction. This condition generally doesn't require repair - just drive normally until the particles fall out. Unbedded Brake Pads: Some owners aggressively brake to quickly bed in new pads that are causing noise. While this may accelerate the bedding process, it also causes excessive pad wear, effectively reducing their service life. It's recommended to drive normally for a period to allow natural bedding instead of forcing premature wear.

My Envision had severe noise from the rear wheels last time. The repair shop found that the rear suspension bushings were aged and cracked, causing squeaking sounds when going over speed bumps. The mechanic said these bushings tend to fail after about five years of driving and need complete replacement. I also noticed an unusually thin wear spot on the inner side of the tire, likely caused by aggressive cornering leading to uneven wear, which created a humming noise at highway speeds. Additionally, a small stone got stuck in the rear brake pads, producing a clicking sound that could be removed manually. After fixing all these issues, the rear wheels became quiet. My advice is not to delay when hearing abnormal noises - promptly check chassis components and tire wear conditions, as neglecting them could dangerously affect vehicle handling.

As a veteran driver who frequently takes long trips, I believe rear wheel noise typically stems from three common issues. The most likely culprit is worn rear wheel bearings, which produce a humming sound that intensifies with speed. Next is the braking system - either stones stuck in brake pads or worn pads reaching the warning indicator position can cause squeaking. For suspension components, pay attention to the stabilizer bar bushings and shock absorbers; cracked bushings will creak when going over bumps. Last time my car had noise issues, it was due to stabilizer bar bushings - when removed, they were found split in two. Don't overlook tire problems either, as stones lodged in tread patterns create rhythmic tapping sounds. All these conditions require lift inspection to confirm the exact cause.

My Envision used to have constant noise from the rear wheels. During , the mechanic said there were sand particles between the brake discs and pads, and the noise disappeared after grinding. They explained that the rear suspension bushings of Buick are made of rubber, which hardens and cracks over time, causing squeaking on bumpy roads, requiring a full replacement. I also noticed that the noise is more obvious when starting the car cold in winter, possibly due to friction from cold contraction of parts. Later, I found that securing items in the trunk can also reduce noise—once, loose camping gear rattling sounded like noise from the chassis. Now, before every long trip, I make it a habit to check the tires for stones or bulges.

A mechanic specializing in told me that the abnormal noise from the rear wheels of the Envision is most likely related to chassis components. Common causes include aging suspension bushings, especially when a clunking sound occurs over speed bumps, which is usually the culprit. Uneven brake discs or foreign objects on the pads can produce high-frequency friction noises. Additionally, damaged rear wheel bearings can generate a continuous humming sound, with noticeable changes in noise when turning. He suggested first checking for stones stuck in the tires and assessing tire wear to rule out simple causes before delving deeper into chassis inspection. Last time my car had abnormal noise, it was caused by uneven tire wear—the inner side had worn smooth, producing a roaring sound like an airplane taking off on the highway. The issue was resolved promptly after a wheel alignment.

I drive the Enclave mostly on mountain roads and found that rear wheel noise is closely related to driving habits. Hard braking can cause brake disc deformation, resulting in squeaking sounds during low-speed turns. It improved a lot after replacing the discs and pads. Worn suspension components like ball joints can also cause noise, especially a metallic knocking sensation on rough roads. A friend upgraded to larger rims and later discovered scratches on the inner side of the rear wheel arches, which was the source of friction noise due to size mismatch. I also noticed that the aging and loose fuel pump bracket caused a rattling resonance on bumpy roads—this requires removing the underbody cover to inspect. Now, I regularly perform chassis inspections, including checking for shock absorber leaks, all of which help prevent noise issues.
