What causes cupped or scalloped tires?
Cupped or scalloped dips appearing around the surface of the tire tread wear could indicate loose, worn or bent suspension parts. Shocks and struts are the most likely culprit because they provide damping force to control tire movement. When the tires move excessively, the scalloped pattern can appear.
What causes tires to be cupped?
Suspension components like shock absorbers, struts, bushings and others wear out with miles travelled. The result can be a tire that is no longer able to roll smoothly down the road; instead, it bounces slightly. This bouncing creates uneven points of pressure on tires, leading to tire cupping.
Why does my Nissan Murano make bad wheel noise?
This effectively changes the wheel alignment repeatedly as you turn, accelerate, and brake. Worse When Turning – Wheel bearing noise will often get worse when you turn. This is particularly true when it’s the front bearings that have gone bad. Louder With Speed – Typically, bad wheel bearing noise will increase as you increase your Murano’s speed.
How to replace front wheel bearing on Nissan Murano?
The only special tools needed to do the replacement quickly is a slide hammer with the FWD hub puller attachment; tools that can be easily rented. Otherwise, the hub assembly could be jarred free from the knuckle with hammer impacts; something I personally do not prefer to do but have know others to have done.
Where is the hub on a Nissan Murano?

What kind of noise does a bad wheel bearing make?
Tires that are misaligned and have been allowed to wear unevenly can also cause a noise that is very similar to wheel bearing noise as well. So be cautious of that. Noises – The most consistent sound that a bad wheel bearing is going to make is a low pitched grinding sound. This noise should be coming from the wheel or tire area.
