Rattle Noise in Front at Slow Speeds over Bumps or Rough Road - keywords brake caliper click L61 L66 L81 movement suspension tick

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Some customers may comment on a rattle type noise coming from the front of the vehicle while driving at slow speeds. Rattle may be most noticeable over rough road surfaces when the brake pedal is not applied. This condition may be caused by the interface between the front brake caliper guide pins and the front brake caliper brackets.

To isolate the brake caliper guide pins as a potential source of the noise, apply the brakes when the noise is apparent. If the noise stops when the brakes are applied and then comes back when the brakes are released, the brake caliper guide pins and grommets are the most likely source of the concern. Replace the front brake caliper guide pins and grommets on both sides. Make sure to install a new rubber grommet on the lower guide pins before installing them. These grommets will be included in the front brake hardware kit for the vehicle. When installing the new guide pins, apply a light, thin coat of high temperature silicone brake lubricant before the pins are installed into the brake caliper bracket.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
