Signs this bushing may need replacing include uneven or accelerated front tire wear, a steering pull, or alignment angles that won't hold spec. If a worn or incorrect caster/camber bushing is the cause, replacing it with the MS40045 restores an adjustment point at the front axle. Have the alignment checked and set after installation.
