BMW 740i Struts

Why Your BMW 740i Struts Have Gone Bad

Aside from being a classy sedan, your BMW 740i is also proven to be a very reliable vehicle. It offers a comfortable ride, which is made possible by the different components in its suspension system. One of these components is the strut. It is responsible for cushioning the impact between the vehicle and the road, therefore ensuring the passengers a smooth and stable journey. But like all other car parts, struts are very much prone to wear and damage. BMW 740i struts are generally tough, but depending on maintenance and vehicle use, they can start to elicit problems as well. Here are common signs that your struts are no longer in top shape and their causes:


Leaks are a recurring problem in automobiles. When you notice them coming from your strut assembly or when oily deposits begin to appear on the strut itself, you might want to check the seal and see if it has worn out. Your strut assembly is composed of tubes, valves, and fluids, which work together to control the bounce of the springs in the suspension system. Now, the seal functions to prevent these fluids from seeping out of the assembly. But because seals are meant to deteriorate eventually because of age, they can cause the strut to leak and become soft and bouncy.

Tire wear and excessive bounce

Unusual tire wear is a common sign of a blown strut. You can easily notice this irregularity once you examine the tire. If it rebounds upward after even a small bump and fails to return to the ground at once, then your strut might be in bad condition. However, a blown strut can also cause excessive bouncing. You can test it by pushing down on the front and rear of your BMW 740i. If your car bounces more than once or twice, your strut might have a damaged cylinder or piston rod.


It's pretty easy to identify a strut problem when you hear a muffled or clunking noise. This sound can usually be heard when you drive over bumps, potholes, or curbs. It is produced when the chassis comes into contact with the suspension parts, which is also a result of a blown strut.

  • Keeping Your BMW 740i Struts in Top Shape

    Struts are vital components of your BMW 740i's suspension system. They are in charge of ensuring a smooth and comfortable ride to the passengers' satisfaction. These parts hold the weight of the vehicle while in motion to adapt to varying road conditions that could cause discomfort. BMW 740i struts are further comprised of suspension parts such as the coil spring, strut bearing, steering knuckle, spring seats, and shock absorber. All these parts work together, and any defect on one component can affect the overall performance of the strut assembly. So keeping your struts and their components in top shape is a must if you don't want any distressing feeling and safety risks while driving. Here are some tips on how you can properly take care of them:

    • Always watch out for warning signs.
    • You need to be observant about the behavior and look of your sedan. Sometimes, the symptoms of a bad strut appear very gradually that you might not even notice them. However, the most common signs that you need to look out for include nose-diving, uneven tire wear, excessive bouncing, and eerie, clunking noises. Once you perceive these irregularities, do a visual inspection on your struts to find out if they are already in need of replacement.
    • Do a regular check-up on your struts.
    • Checking your struts once a year is ideal, and it should be done in conjunction with a wheel alignment. These two parts are strongly tied to each other because they connect to a spindle. So if you find the need to replace your struts, you would also have to consider checking the wheel alignment. The caster and camber can actually change after putting in new struts, as well as the toe adjustment. If you fail to inspect the alignment after replacing the struts, chances are your tires would wear unevenly and sooner than expected. In examining the struts, remember to look out for leaks, dents, and worn bushings as well.
    • Know when to replace the struts.
    • Generally, it is advised to replace the original equipment struts after 50,000 miles. But because people have different driving styles, the life of the struts can either be shortened or prolonged. The roads on which you drive your BMW 740i can also play a part on how long you can keep your struts in good condition. If you frequently drive on rough roads, then your struts are more likely to wear faster.It is also important to note that it's normal for the front struts to wear more quickly than the rears because most of the braking is handled by the front struts.
