LL6 Resolve Inconsistent Air Gap Concern

- Remove the front disc brake hub and rotor and inspect the tone ring/hub mounting surface. Verify the tone ring is pressed straight and fully onto the hub. Correct before proceeding.

- Reinstall the front disc brake hub and rotor.

- Verify wheel end play is within allowable limits.

- Measure the air gap between the speed sensor and tone ring teeth. Repeat in at least two more wheel positions to ensure that gap does not vary as the wheel is turned.

NOTE: Feeler gauges can be mounted to a welding rod and inserted between the vanes of the front disc brake hub and rotor to measure air gap precisely.

- Is the gap consistent and less than 1.78mm (0.070 inch)?

YES -- Go to LL5 to recheck speed sensor output. LL5 Recheck Front Left Speed Sensor Output

NO -- Gap is greater than 1.78mm (0.070 inch). Air gap is too large. Go to LL4 to resolve large air gap concern. LL4 Check Speed Sensor/Tone Ring Air Gap

NO -- Gap is not consistent. Repeat LL6. LL6 Resolve Inconsistent Air Gap Concern Do not leave this step until a consistent air gap is obtained.
