Initial Inspection and Diagnostic Overview

^ If the axle fails to operate, there will be broken or jammed-up parts. Analyze why the parts have broken to prevent the condition from recurring.
^ Lock-up or seizure of the rear axle usually indicates inadequate lubrication. The lubricant prevents friction and helps cool the parts as they heat up. Without enough lubricant, the heated parts get soft and may eventually weld together. Check for lubricant leaks after servicing.
