Knocking noise in passenger wheel well

Postby andrewbenton » Thu Sep 08, 2011 2:44 pm

I have had an issue in my S60 for the past few months, it seems to get worse when it is cold out. It's a knocking noise in the front right wheel well when I go over any kind of bumps, even cracks or cracks that were covered up by tar. It is worse at low speeds, mostly because I can hear it more I think.

Any advice would be appreciated.

Since the knocking is affected by road conditions and you didn't mention engine/wheel speed, we can safely assume its a suspension problem and not a drivetrain problem. If its knocking frequency went up as you sped up you might suspect a rotating part such as wheel, axle, CV joint, etc.

Since this is getting worse, you can safely assume it is wearing more. As these wear, they tend to start wearing faster - meaning once they start going bad they go bad faster and faster.

So, you should look at the wear parts of your front suspension. Common ones are bushing and ball joints. The weakest link in there is the stabilizer (sway) bar link. Another might be your front struts failing.

To quick and dirty test the struts, get someone strong/heavy to push down really hard on the front right corner of the car bumper. Push down ONE time and release really fast. Maybe even step onto the bumper and jump down once as you jump off. One big push down and release. Working shocks/struts should bounce up then down once. Weak or failing shocks will bouncy bouncy bounce.

What I would do is Jack the car up and remove that wheel. Securely block and "stand" the vehicle so its rock solid stable. You can visually inspect through the wheel well and from underneath. Look for oil leakage around the strut which could indicate the strut seals failed and wore out.

Look at the bushings for missing rubber - it can be brittle and crack-y looking if older but there should be rubber in there.

Most importantly, inspect the rods that have ball joints. There is a thin straight vertical rod with a ball joint on both ends. That should be snug between its two mounts. If you can wiggle it or push it, you've found your problem.

Good luck.

Your car is experiencing broken spring seats at minimum. These sit on top of the strut and wear out over time, causing a knocking or clunking sound over rough stuff (or when its cold, strut is very stiff when cold). There are also bearing plates that these seats mount up against, those can wear out also but dont cause the noise you are hearing, its a good time to change them if they are worn and its all apart. I just changed them on my own personal car over the weekend, makes an amazing difference when they are fixed, car rides so much nicer. Email if you have any questions, we sell em for $35.46.

Is the "clunk" more like a loud "click"? I'm thinking "sway bar end links". they go out after about 60-90K miles, are easy to replace (especially the second time) and only require some simple tools.

A knocking noise on the pass side could also be a bad engine mount.
The mount is under the crankshaft pulley.
