Strut mounts have multiple roles: First, they have to keep struts firmly in place and absorb some of the shocks from road bumps. Second, in some cars front strut mounts have strut mount bearings to allow rotation together with front wheel when turning left or right. Considering this, are strut mounts important?
Worn strut mounts or bearing plates can adversely affect vehicle handling and safety as they are an important component of the suspension system. Worn strut mounts and bearing plates can cause noise, steering binding or even be the cause of steering pull.
One may also ask, what does a strut mount do? Fitted on cars equipped with Macpherson type struts, the top strut mount attaches the top of the strut to the vehicle's chassis. Its purpose, however, extends far beyond a simple mount. Indeed the top strut mount has two main roles; it insulates the strut from the vehicle, reducing both noise and vibration.
Also to know is, can I drive with a bad strut mount?
If your suspension is out, you can still, technically, drive your car. You're not going to enjoy the ride much, though. What's more important is that your vehicle is not protected from an uneven road surface and could deteriorate quickly or cause an accident.
Do you need an alignment after replacing strut mounts?
Replacing those struts requires no alignment.

What causes bad strut mounts?
Other causes of a faulty strut mount include impact damage and contamination. Minor accidents and bad weather may affect the strut mount and cause it to fail prematurely. At the first sign of wear, consider replacing your vehicle's strut mounts immediately. What noise does a bad strut mount make?
Noises coming from a failing strut mount have been described as clunking, knocking, creaking, and grinding. These are usually more obvious when hitting potholes or speed bumps, driving on rough ground, or driving at low speeds while turning the wheels all the way to the stops. Are left and right strut mounts the same?
Short answer: yes and no. OEM or original equiptment yes it does. Your break line will attach on the R or L side, but some manufacturers put bilateral brackets so is can go on either side. Check for this and any mounting changes from either side. How long should strut mounts last?
How Long Do Strut Mounts Last? A correctly installed strut should last at least ten years, depending on where you live. If you're in a rural area and go off-roading often or live in a coastal area or where road salt is used in the winter, you're dooming the mounts to a shorter lifespan. Can you replace just the strut mount?
Like other chassis components, suspension strut mounts should always be replaced in pairs. The top fastening of the suspension strut is attached to the chassis via the strut mount – also known as the suspension strut mount. How long can I drive with bad strut mounts?
It will obviously be a bumpy ride, but you can drive in a car with bad struts. Eight hours of driving can easily eat up a tire with a strut in that bad a condition. What does a bad strut feel like?
You'll notice the front end of your vehicle rising while the rear “squats” during hard acceleration. Tires bouncing excessively. After hitting a bump, you can feel a tire (or tires) reacting or “bouncing” for a time. You may also hear a clunking noise. How do I quiet noisy strut mounts?
Take the wheel off, and spray WD-40, or silicone, or engine or transmission oil, lubricant generously at the top (and bottom) of the strut coils. What happens if a strut mount breaks?
What happens if a strut mount breaks? When a strut is broken, one area of the vehicle is free to move farther and faster than the others. This increases the wear on the other suspension components and may cause the failure of these components. When should strut mounts be replaced?
A simple rule of thumb is that if the struts or coil springs are being replaced because of age or wear, then also replace the mounts. A worn or damaged mount can cause a variety of symptoms so they should be inspected by a qualified technician. Should top strut mount move?
A slight downward movement is normal, but any side-to-side movement could indicate a defective mount. Push in and out on the strut and spring while watching for movement of the upper end of the strut piston rod. There should be no free movement. If there is excessive movement, the upper strut mount should be replaced. What is the cost of replacing struts?
The average cost for a strut replacement generally runs between $450 and $900 to replace a pair. If you are just replacing a single strut, the repair price will come to between $130 and $300, while labor will cost you between $150 and $300 for the pair. Do quick struts come with mounts?
Quick struts come with mounts. The front ones have a set of bearings and they do wear out. The rear does not have bearings and probably does not need replacing. Are shocks and struts the same thing?
What is the difference? A shock absorber on an automobile does one thing and one thing only, keeps the car from bouncing. Struts are considerably different. Struts are a structural part of the suspension system and are mounted to the chassis of the vehicle on the top, and they come down through. Can you put struts on wrong?
The struts aren't side specific. The OEM coils and shocks are the same for both sides. Reversing them should have no effect.
