I hear some strange noises that seem to be coming from the vehicle's steering assembly. There's whining whenever I turn the steering wheel to a certain direction. Where is this noise coming from? Help!
The steering system of the vehicle needs some quick inspection. This will reveal the source of the noise and root of the problem. One of the possible causes is a damaged or loose steering drive belt. If everything looks okay with the belt, move on to other items on your checklist. This should include the steering system fluid. Check the level and top it off as needed. If there's air in it, then the system should be bled out. Another thing you can do to fix this is to take a look at the mount for the steering pump. If it's loose, then this has to be re-tightened or adjusted. If there's damage, then have this replaced.
How can I figure out if the tires of my Mercury have camber wear? What are the indicators? What causes camber wear?
Camber refers to how tires are leaning. If the tires have negative camber, the top of the tire tilts towards the vehicle, while for positive camber, the tires lean away from the vehicle. Good tires should have little to no camber. If they do, then unusual wear develops on tires. In the case of positive camber, the wear pattern goes like this: a smooth, tight strip of wear can be spotted on the tire's outer shoulder. Meanwhile, wear on negative camber will be spotted on the inner shoulder. This kind of wear happens due to improper tire inflation. This can also be caused by misaligned wheels or bad suspension components. If the tires have adequate tire pressure but still there's camber wear, the problem should be diagnosed by a professional. Take the tire/s to a service center or tire specialist to have them checked.
What are the usual wear patterns of negative toe and positive toe on tires?
Toe is all about angles at which the tires are aligned. If the front of the tires are angled inward, then tires are what they say toe-in. They have a positive toe. But if the front of the tires have an outward angle, then the condition is called toe-out, or negative toe. It's not unusual for tires to have a bit of toe. However, toe issues can surface if the wheels are bumped out of alignment, leading to premature tire wear. Toe wear is best described as wear that develops on the tire's inner shoulder. To prevent toe wear, the wheels should be aligned properly and adjusted accordingly.
Is it normal for rotors to have an edge lip?
If the rotors have noticeable edge lips, then this means that the rotors are worn out. An outer lip is formed when the brake pads no longer touch or get in contact with all of the rotor surface. If the lip is noticeable or obvious, this could mean that the rotors are about to reach their wear limit or they suffer from uneven wear.
