- When checking the front end, which of the following are NOT cause for rejection? Bearing cap is broken or missing or if there are any cracks or welded repairs to any components. Front axle is bent or gear box mounting is loose, bolts are missing, or bolts or case are cracked. All of the statements shown are cause for rejection. The steering damper leaks, is loose, mount is cracked/ broken, or is missing or steering shaft coupler/universal is binding, frayed, or cracked.arrow_forwardWhile discussing steering problems: Technician A says that a “jerky” steering wheel and a “clunking” noise could indicate worn steering column U-joints.
