BMW 330Ci Sway Bar: Usual Issues and the Culprits behind Them

Also known as the stabilizer bar, the sway bar of your BMW 330Ci is one of the most important components of its suspension system. With the help of this part, body roll is reduced, therefore making your ride more comfortable and safer. Unfortunately, even though it is made from high-quality parts, this bar eventually causes problems because of damage. Listed below are some of the common issues that you may encounter with your sway bar:

Rattling noises

If you're hearing rattling noises coming from underneath your vehicle, then you should check the sway bar for any sign of damage. Usually, when the bar is broken, it moves around a lot because it is no longer bolted properly to the suspension. And so, once you go over bumps or potholes, you will hear rattling noises that can be bothersome over time. To solve this problem, you need to replace the sway bar immediately. However, make sure that the replacement you are going to buy is designed to fit your vehicle. Also, don't forget to tighten the bolts and screws properly so that the sway bar will not become loose after some time.

Understeer

Another problem that you may encounter with your BMW 330Ci sway bar is understeer. Characterized as experiencing driving instability, this problem is caused by pressure loss in the suspension system that is usually triggered by a broken sway bar. If this problem is not fixed at once, it will be very difficult for you to steer your vehicle even during slight turns. Although taking your vehicle to a service center is the best solution, you can also try installing a replacement at home as long as you have the right tools.

Roll-under

Just like understeer, roll-under, is also caused by having a faulty sway bar. You will know that you are experiencing this problem if your 330Ci leans excessively and dangerously to one side after making high-speed and tight turns. Because roll-under is also a safety concern, it has to be solved immediately. You can do this by replacing the damaged sway bar. However, make sure that the replacement you are going to purchase is made from high-quality materials and that you have the right tools such as an open-end wrench set, floor jack, and tire iron.

  • Ways to Keep Your BMW 330Ci Sway Bar in Good Shape 27 February 2013

    Stabilizer bar, anti-roll bar, and sway bar-whatever you want to call it, this particular component of your BMW 330Ci's suspension system is a very significant part. Typically made from high-quality materials, this bar is engineered to level each side of your vehicle to reduce body roll or sideways tilting. Unfortunately, even if it is designed to last, the sway bar will still get damaged especially if it is not maintained properly. Read on to know some simple tips on how you can make your sway bar in top condition.


    Inspect the sway bar for signs of damage routinely.


    One way to make sure that your BMW 330 Ci sway bar will last for a long time is by inspecting it for any signs of damage routinely. By doing so, you will prevent handling problems such as understeer and roll-under. For instance, the rear sway bar should not show any signs of corrosion, and its retaining screws or bolts should not be missing. However, make sure that you have the right tools such as jack stands and a floor jack because the sway bar is located under your vehicle.


    Lubricate the bushings of the sway bar for optimum performance.


    Lubricating the bushings of your vehicle's sway bar with an all-purpose silicone lubricant is a great way to keep the bar in top condition. Doing this routinely will help prevent sway bar noise and other problems. Just make sure that you will use a silicone-based lubricant because an oil-based one is not ideal. Also, do not grease the bushings if they are rubber because doing so will cause deterioration.


    Tighten the sway bar when necessary.


    Over time your BMW 330Ci sway bar will become loose due to worn out bushings and other factors. Once this happens, your driving experience will be less comfortable because of body roll and excessive lean. To prevent this, you should tighten your vehicle's sway bar when necessary. You can do this with the help of a sway bar link bushing kit, torque wrench, ratchet, socket set, and combination wrench. However, make sure that you will not over tighten the bar because this will result to a less comfortable ride.
