Technician should not replace the bearing for grease purge.

noise.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2012/MC-10112519-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2012/MC-10112519-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10112519","components":[{"id":"suspension","name":"Suspension","parent":null},{"id":"wheels","name":"Wheels","parent":null},{"id":"wheel-bearing","name":"Wheel
