Identifying Common Volvo XC90 Strut Mount Bushing Problems
The strut mount bushings of the Volvo XC90 SUV are designed to reduce the shock and vibration that the struts receive from the road, so it shouldn't be much of a surprise that the strut mount bushing will also start to wear out from these stresses. Strut mount bushings are typically replaced along with the struts once after every 50,000 to 70,000 miles, but once they already start to show signs of wear they must be inspected and replaced if necessary at the earliest possible time. The following are some of the common tell-tale symptoms of eventual Volvo XC90 strut mount bushing failure and how to troubleshoot them.
Too much noise and vibration
One of the first and most common symptoms of strut mount bushing failure is excessive noise and vibration from the struts. Since the bushings help minimize vibration, the vehicle would start to vibrate louder and more frequently than normal. Volvo XC90 owners whose strut mount bushings have failed have reported hearing popping noises from the strut and abnormal vibrations that last even when the engine is switched off. In addition, vehicles with bad strut mount bushings tend to rattle when going even minor bumps, particularly when the tires and suspension are still cold.
If one of the tires blows out when driving, one of its probable causes might be a worn or damaged strut mount bushing. Once you've replaced the blown tire, lift your vehicle off the ground and check the strut mounts. Once the bumps fail and the wheels go over a bump in the road, the vehicle would actually separate from the suspension. The wheel would then rest itself at an angle either out or in depending on the terrain. This in turn would lead to an excessive positive camber that damages the tire and eventually causing it to blow out.
Worn or damaged strut mount bushings have also been known the cause the condition called
memory stir, wherein the steering wheel is turned and once released, it does not return back to the center. This is highly dangerous as you will have to manually return the steering to the center, which could inadvertently steer the vehicle and cause a collision.
Maintenance Tips to Help Keep Your Volvo XC90 Strut Mount Bushing Healthy
You might be the kind of driver who drives like there's no tomorrow. You might not care if your car goes over bumps and road debris while you're driving fast. You just bought your car and you tell yourself this is what your struts do anyway-they're supposed to absorb the force coming from road elements. After a few weeks, you feel the vibrations inside your cabin increase. You feel like some of your suspension components have gone loose, and you hear rattling noises coming from the front of your vehicle. Your Volvo XC90 strut mount bushing has given up on you because you have not been taking good care of it. Don't worry, we've got you covered-we can show you how to take care of this small component that keeps your struts healthy.
Perform tire alignment regularly.
One of the benefits of tire alignment is to get more mileage out of your tires. They can be affected greatly by the slightest misalignment. For instance, if your tires have too much or too little toe-in, your tires will wear down very quickly. The increased pressure applied to your struts caused by the decreased performance of your tires can cause your strut mount bushings to eventually develop cracks. Of course, you'll be forced to install new tires if that happens, but you might notice that after replacing your tires, your suspension still has problems. By getting regular wheel alignments, you can make sure that your tires wear evenly and last longer. This can have a significant effect on your smooth driving and will translate into a longer life for your strut mount bushing.
Take care when replacing your strut mount bushing.
Aside from taking care of your wheel alignment regularly, you need to take extra care of new strut mount bushings when performing a replacement. One component that might cause great damage to new bushings is the wheel spindle mount. This component is attached to the strut by two large strut mounting bolts, and once you have removed these bolts, there is a danger of the wheel spindle mount dropping to the ground. Attach it to a piece of wire or string to keep it from getting loose and damaging any of the strut mount bushings.
