Buick Excelle Makes Abnormal Noise When Turning Right and Accelerating?

Based on your vehicle model and the symptoms described, the main possible causes are as follows: 1. CV joint; If the dust cover of the vehicle's half-shaft CV joint is damaged or the CV joint performance deteriorates, abnormal noise will occur when turning, and the sound is relatively sharp. 2. Friction phenomenon; This refers to the friction between the inner fender liner and the tire, and the sound is a 'squeaking' type. In summary, considering the conditions under which the vehicle's symptoms occur and based on repair case analysis, the above phenomena are generally the most common. However, it is recommended that you visit a repair shop for an on-site test drive to determine the specific cause of the fault before proceeding with repairs.

My old Buick Excelle has been making a rattling noise when accelerating during right turns recently, it sounds like metal friction. Last time I took it to the repair shop, the mechanic said it's most likely due to wear on the outer CV joint of the right axle. When turning, the wheel angle increases, causing the worn CV joint to make abnormal noises. It could also be loose steering tie rod ends, which creak under stress during turns. Remember to check if the power steering fluid is sufficient, as low fluid can cause the power steering pump to whine. This issue shouldn't be delayed – a friend's car had similar noises ignored, and the CV joint completely failed and locked the wheel, nearly causing an accident. It's recommended to get it professionally inspected on a lift as soon as possible. If the outer CV joint boot is torn and leaking grease, it needs immediate replacement.

Many Buick Excelle owners have reported turning noise issues, which I analyze mainly come from several areas. The most likely cause is damaged CV joints, because when turning right, the right wheel bears greater torque, causing aged CV joints to make clunking sounds. Another possibility is loose wheel hub bearings, which produce a humming noise at higher speeds. During inspection, first identify the noise location - if it's from the front, it could be steering gear or power steering pump issues; if from the wheel area, focus on suspension components. Also check if brake pads have trapped foreign objects like stones - last time my car had a nail stuck in the tire tread that made scraping noises when turning. For repairs, CV joint boots cost around a hundred yuan to replace, but require special tools for proper installation.

My Buick Excelle also had a similar issue - there was a metallic knocking sound from the chassis when accelerating during right turns. The mechanic spent twenty minutes checking with a lift and found that the lower control arm rubber bushing was cracked. During turns, the wheel displacement increases, and when the bushing's cushioning fails, it causes direct metal-to-metal contact. He also reminded me that turning the steering wheel to full lock is most likely to damage the CV joint. A simple test method: turn the steering left and right while stationary to listen for abnormal noises (which might indicate steering gear issues), and if the noise only occurs while driving, focus on inspecting the suspension system. Remember not to keep the steering at full lock for extended periods during turns, as it can seriously damage the power steering pump.
