What Causes the Rattling Noise When an Eighth-Generation Accord Drives on Bumpy Roads?
2 Answers
There are several reasons why an eighth-generation Accord may produce a rattling noise when driving on bumpy roads: 1. Body noise: This is usually caused by insufficient body rigidity, leading to deformation during driving, resulting in friction or shaking between doors and door frames, or friction between steel plates due to welding failures in certain areas. Applying adhesive strips on doors and windows or placing rubber pads at friction points may help reduce or eliminate the noise. 2. Engine compartment noise: There are various possibilities for noise originating here. A high-pitched belt squeal is typically caused by belt slippage. If there is a sound of metal parts rubbing against each other while the engine is running, it usually indicates damage to the bearings of the generator, water pump, or power steering pump.
I've been driving an eighth-generation Accord for many years, and the car does make a clunking sound when going over bumpy roads, which is usually not a minor issue. The sound comes from the aging suspension system, such as worn or loose shock absorber top mounts, which vibrate and make noise when hitting potholes. It could also be due to loose stabilizer bar links or cracked control arm bushings, causing parts to collide. I recommend getting it checked as soon as possible because ignoring it can accelerate damage to other components, such as wheel bearings, ultimately increasing repair costs. Regularly performing a simple check of the chassis before driving to look for obvious looseness can help identify problems early.
