F-552901.02 / F-567535 03 / F-239973.04 Freewheel Clutch Alternator F-553392.01 / F-558658.01 Freewheel Pulley

F‑552901.02,F‑567535 03,F‑239973.04,F‑553392.01,F‑558658.01 are Schaeffler FAG/INA original serial double row open angular contact ball bearings, dedicated pinion & side bearings for European luxury sedan/SUV rear differential assemblies, covering BMW Type168L/188L and Mercedes W204/W211/W164 rear axle diff overhaul matching.

All models adopt double ball raceway integrated outer ring open non-sealed design, matching differential circulating gear oil lubrication system, no grease sealing obstruction. The double-row structure bears heavy bidirectional axial & combined radial impact loads during vehicle acceleration/deceleration, effectively eliminate rear axle whining, humming abnormal noise caused by original bearing wear. Each model corresponds to exclusive diff housing size and vehicle platform, cannot cross substitute freely, widely supplied to auto repair shops, differential rebuild factories and global auto aftermarket spare parts distributors.
