Bentley Flying Spur pulling to the right when driving on a straight road not only reduces driving comfort as you continuously have to adjust the steering wheel to keep the vehicle in your lane, but it also signals an underlying fault that can compromise your road safety. In this article we go through all the reasons that can cause your Flying Spur to veer right and how you can fix it.
The most common causes for Bentley Flying Spur pulling to the right when driving are bad wheel alignment, tire pressure lower in right tires than the left tires, uneven tire wear, and defective wheel bearing. Some other issues that can cause Flying Spur to pull to the right are worn suspension and steering components, sticking brake caliper, bent rim, road crown or the road slopes to the right, mismatched tires, and defective tires.
1. Bad wheel alignment
Misaligned wheels is one of the leading cause of Bentley Flying Spur pulling to the right when driving on a straight road. Wheel alignment is an important and often overlooked aspect of maintenance. Potholes and curbs can easily misalign your wheels, resulting in poor control and excessive wear on your tires.
What are the symptoms of bad wheel alignment in Bentley Flying Spur?
The most obvious sign of misaligned wheels in Flying Spur is when your vehicle pulls to one side and you constantly have to adjust the steering wheel to drive in a straight line. Some other signs include uneven or rapid tire wear, crooked steering wheel when driving straight and squealing tires.
How is wheel alignment performed on Bentley Flying Spur?
Wheel alignment is primarily carried out using electrical diagnostic tools. Using sensors that are attached to the wheels of Flying Spur, a computer system recognizes the extent to which the actual values deviate from the target values. The target values are the standardized values specified by the manufacturer. The measured values can be compared on a computer and deviations are interpreted and corrected directly.
How often should wheel alignment be performed on Bentley Flying Spur?
In contrast to wearing parts, there are no fixed maintenance intervals or manufacturer specifications for wheel alignment. Therefore, such a review is usually at your own discretion. Nevertheless, it is advisable to check the treads at least as part of the tire rotation every six months or 5,000 to 7,000 miles. Do note that driving habits can heavily influence how often you need to get your Flying Spur wheels aligned.
2. Incorrect tire pressure
Incorrect tire pressure in one or more of the tires can also make your Bentley Flying Spur pull to the right when driving. Lower tire pressure increases the contact area of the tire tread with the road surface which leads to higher road grip and friction. If the air pressure in the right side tires is less than the tires on the left side, your vehicle will pull to the right due to higher drag on the right tires.
If your Flying Spur is equipped with tire pressure monitoring system, also called TPMS, the amber colored low tire pressure warning light may illuminate in the instrument cluster in case of incorrect tire pressure.
Check tire pressure
Reinflate all the tires of your Flying Spur to the manufacturer specified air pressure, which is mentioned on the vehicle placard or tire inflation pressure label usually located on the B-pillar or the edge of the driver door. If you can’t find the label, check the owners manual of your vehicle.
3. Uneven tire wear
Uneven tire wear can also cause your Flying Spur to pull to the right when driving. Uneven tire wear can have many causes, most often it is caused by driving with incorrect tire pressure or bad wheel alignment for too long. If your car is still pulling right with the correct tire pressures and wheel alignment, you should check for uneven tire wear.
How to check uneven tire wear in Flying Spur
Spotting uneven tire wear in your Flying Spur is easy. You just have to examine the tire tread for abnormal wear. For example, if the inner or outer edge of the tire is wearing down faster than the rest of the tread, bad wheel alignment is the most likely culprit.
Will replacing the tires fix the issue of Flying Spur pulling to the right?
If your Flying Spur is pulling to the right due to uneven tire wear, replacing the tires should rectify the issue. But, if you replace the tires without finding and fixing the underlying cause of uneven tire wear, the new tires will also wear out unevenly and you may end up with the same problem of car pulling to the right. Therefore, if uneven tire wear is discovered, it is highly recommended to get the wheel alignment done, and check for any issues with the suspension and steering parts before installing new tires.
4. Bad wheel bearing
A defective wheel bearing can be the cause of Bentley Flying Spur pulling to the right. The most common signs of bad wheel bearing are grinding noise in the cabin when driving straight, a knocking noise when cornering, and the vehicle vibrates. The faster you drive, the louder the grinding noise and stronger the vibration.
What causes bearings to fail in Bentley Flying Spur?
Even when driving your Flying Spur in a straight line, the bearings have to absorb high radial forces. The entire weight of the vehicle rests on the bearings. When driving, the speed creates additional forces. If a curve is then also driven through, axial forces occur. High impacts on the bearings also occur on uneven roads or when driving through potholes. Impacts of all kinds are much more damaging to bearings than the high loads. Therefore, all wheel bearings eventually fail. However, how soon they fail depends on driving habits.
5. Worn suspension and steering components
Looseness in suspension or steering system components can cause uneven tire wear and can also make your Flying Spur pull to the right. Overly worn ball joints or tie rod ends makes it difficult to properly align your vehicle. Some common signs include vibrations from the front end or through the steering wheel, clunking or rattling noise coming from your front suspension especially when going over speed bumps or when turning the vehicle. In extreme cases, your front end can not only vibrate but also shake violently at high speeds, this phenomenon has been nicknamed “death wobble”.
6. Sticking brake caliper
If the brake pad on the right front wheel or the right rear wheel is continuously rubbing against the rotor when the brake pedal is not depressed, it can not only cause excessive overheating and burning smell, but will also pull Flying Spur to the right side. One of the most common cause of sticking brakes is stuck brake caliper, but can also happen due to other defects in the braking system or improper installation.
How to check for sticking brakes
Since sticking brakes cause overheating, the easiest method is to measure the temperature of the brake rotors with an infrared thermometer after a test drive. If you do not have the instrument, you can splash some water onto the rotors. If the water sizzles and evaporates instantly on contact, it means your Flying Spur brakes are sticking. Be careful not to splash too much water, as it can damage the rotor.
You can also feel the temperature on the outer side of the rims. If one of the rims is significantly warmer than the others, the brake caliper may be dragging. Do not touch the rotor or brake caliper to check the temperature as it may burn your hand.
7. Bent rim
A bent rim can also cause your Bentley Flying Spur to pull to the right side of the road. Such damage usually occurs when obstacles such as curbs, speed bumps or deep potholes are driven over too quickly. This may also lead to vibration especially when driving at high speeds. Balancing the wheels and performing wheel alignment would probably not fix the problem, a bent rim must be replaced.
Even if there is no visible damage, the whole rim could be deformed resulting in uneven diameter. An experienced mechanic can tell if the rim is bent by mounting it on the wheel balancing machine.
8. Road crown
Your Flying Spur may be pulling to the right due to the angle of the road and not due to a fault. Crown is the side to side, or the cross-sectional shape of a road surface. Most common type of road surface designs are center-crowned, in-sloped, or out-sloped. If the slope is towards the right side of the road, your vehicle may veer towards the right side as well, the intensity of the pull depends on the angle of the slope.
The central task of the road crown is to drain surface water from the road surface as quickly and harmlessly as possible in order to protect the road structure from moisture penetrating and to prevent water accumulation and its consequences (aquaplaning, water splashing or black ice formation) on the surface.
9. Mismatched tires
Using mismatched tires can also cause your vehicle to veer to the right. All the wheels and tires on your Flying Spur must be of the same size. If the right side wheels have wider tires than the ones on the left side, the vehicle will pull to the right due to higher friction.
The vehicle will also pull to the right if the diameter of the tires is smaller on the right side than the left. For example, it is common for a car to veer to the direction where a compact spare tire (also called donut tire) is installed in case of a flat tire.
10. Defective tire
Did your Flying Spur start pulling to the right after you installed new tires on the rims? In very rare cases a defective tire could be the cause.
How to check for a defective tire
The easiest way to check if one of the tire is causing the vehicle to veer right is by swapping the right side wheels with the left side. If the vehicle veers left after the swap, it indicates a defect in a tire or a rim.
There are many reasons why your Bentley Flying Spur is pulling to the right when driving. When looking for the reason, you should always start with the most obvious causes, misaligned wheels or incorrect tire pressure.
