2004 E320 Mercedes Benz squeaky Noise occasionally from left wheel area when driving. I have replaced tires and alignment is complete. No leaks spotted on left side suspension systems during tire replacement. Can you guys what's going on so I can get it fixed?
My car has 150000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there – this noise could be from suspension link or bushing(control arm or sway bar), or from the spring seats. This is the sort of random noise that springs up after some years of service. Will probably require putting the car up on a lift, with a helper to press down on the front fender to simulate a bump, to help locate exactly what. For assistance with diagnosis, I recommend a suspension inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
This occurrence is fairly common with brand-new Mercedes-Benz and brake pads since Mercedes-Benz uses high-performance semi-metallic brakes. With brake pads rubbing against metal brake rotors, the squeaking noise is normal, especially with the dust accumulation.
Vehicle Suspension
Besides brakes squeaking, the most common squeaks are usually associated with your vehicle`s suspension. The squeaking suspension parts are often associated with a lack of lubrication when metal-on-metal wear is happening in connections such as the tie-rods, suspension joints and steering linkage.
The steering and suspension parts that connect your wheels to your car contain several rubber bushings, as well as ball and socket joints. Worn bushings or joints can cause a squeak when going over bumps. These noises can be hard to identify because they often don`t happen all the time.
You need to replace your brake pads if they squeak while you`re driving but no brakes are applied. The brake wear indicator, a metal clamp that fastens to the brake pads, usually comes with your brake pads when you buy them. These pads deteriorate over time, which forces them to grind against the rotors.
A squeaky suspension system is not just embarrassing with those squeaking noises and grinding noises, but it is also dangerous and can be extremely difficult to diagnose and fix. Your vehicle`s weight is supported using coil springs, leaf springs or torsion bars.
The first indication of any trouble with suspension will probably come from an unusual noise. There`ll be a knocking, creaking or clanking from under the car. In extreme cases, your car might not want to drive in a straight line without you constantly making adjustments with the steering wheel.
Suspension squeaks/squawks: Unlike clunks, a squeaking noise from the suspension almost always means a dry rubber bushing and these can be left until they`re unbearable to your ears or until they change to a clunk.
Can you spray WD-40 on a suspension? Yes but it`s not going to stay on your suspension it evaporates. But it can be used as a method of finding what is actually squeaking. But it will not resolve the problem.
If the squeaks are loud or if the bushings look damaged, it`s better (and safer) to have them replaced. Bushings vary wildly in price, from around $5 to $300, plus labor costs to have them installed. But chances are the AT-205 Reseal will get the job done in most instances.
Whether you`re just driving down the road, braking, or you`re running over a pothole or rough patch, if you`re hearing squeaking from your suspension then it`s time to bring your car in to have your shocks and struts inspected for wear.
Everything from the lower control arm with the control arm bushings – which connect the control arm with the frame of the vehicle – to the ball joints can cause suspension noises. Some vehicles – due to age and wear – are more prone to a creaking or groaning noise when the wheel is turned.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.
Loud repetitive noise coming from front tire in 2 wheel drive, goes away when in 4 wheel drive.
ANSWER : Hello, thank you for writing in. Chances are there was an existing issue that was amplified by the tire rotation. There are several parts that will cause similar symptoms. You will want to consider the parts that are under load in 4wd, that are free when in 2wd. This would include the axle and sveral joints. There are a couple of tests that can be done. More damage was likely done driving on dry pavement in 4wd. It was a good step in diagnostics, but should be avoided. For more help with diagnosing the sounds, contact our service department to schedule an appointment.
Very Loud Knocking noise from left rear wheel when turning left and braking
ANSWER : The problem could be in the transfer case unit, but the device is mounted closer to the driver than the rear wheel so the noises or vibrations are generally a little more obvious. Especially during sharp turns the transfer case and rear end assemblies are working pretty hard with the wheels turning at different rates. I suggest hiring one of our mobile experts to diagnose the noise you’re hearing. Wheel bearings and worn out suspension components like sway bar links cause similar noises.
Rattling noise from front left during left turns or while going over bumps.
ANSWER : Hi there. Base on the information you’ve provided this may be a result of the leveling kit installation. I would check the caliper on the left front and make sure the mounting bolts for the caliper and pads are proper tightened. Then check the installation of the shock to see if the nut is overtightened and squeezing the bushing flat; simply look a the top of the shock and see if the bushing is flat and allowing the metal washers to make contact. Also check the sway bar link for similar signs as noted for checking the shock. The last thing that I would suspect is a wheel bearing that may not have been properly tightened or may need to be torqued. YourMechanic has several technicians that can provide you with a proper suspension inspection for the noise and advise you further on repairs.
I own a 2000 f150 lariat 4 x4. 5.4 l. Started getting a loud grinding noise front passager brakes. Replaced brakes and wheel
ANSWER : Hi there. While using junkyard or used parts (especially brake or suspension parts) is highly discouraged and can cause major damage, it is unlikely that they caused the aluminum wheel to split in half. In most cases, this is caused by hitting a pothole or other obstruction in the road. A glancing blow against a blunt object like a curb can also cause this type of damage. However, if the brakes came apart or a brake component broke, it could in theory cause the same damage. My advice to you is to not drive the vehicle further until you’ve replaced the brakes and wheels with new components for safety.
When I turn my car slightly to the left, I hear a humming noise almost like a rubbing noise. The steering wheel doesnt vibrate
ANSWER : The noise could be from the wheel bearing rubbing as it may have dry grease inside the bearing. The noise also could be the power steering pump as there is a load applied to the pump more than steering the other direction. Also, check the tires on the vehicle and see if the tread is rubbing on the fender or the frame as if the tires may be too wide for the steering of the vehicle.
If you need further assistance with the vehicle making a rubbing noise when turning to the left, then seek out a professional, such as one from Your Mechanic, to help you.
Noisy left wheel area when driving over a bump
ANSWER : The suspension system uses rubber bushings and dampers to soften the blow when a vehicle is riding through a rough surface. These components may be worn or in need of lubrication. Have an experienced technician, like one from YourMechanic inspect all suspension components.
