The Axle bushing and hub bearing lubrication modification product from Courtsara allows users to service the front driven steer axles on Class 6 and 7 trucks. Normally, to pack the hub bearings and the spindle bushing, it would take 16 or more hours, says the company. With its process, this can be done in 10 minutes, without removing the brake drum or even the tire. The axles it pertains to are the Fabco 1200, 1400 and 1600; Marmon-Herrington CT8, MT8, MT10, MT11 and CT12; and Meritor 120, 140 and 160.
