Engine Crankshaft Thrust Washer – Ford (ft4z6337aa)

Engine Crankshaft Thrust Washer carries rotating load and sets the running clearance for the shaft it supports. Wear is progressive, so the first symptom is usually noise in a narrow speed or load band rather than a sudden failure.

Replace the Crankshaft Thrust Washer when you can hear a rumble that changes with speed, feel roughness turning the shaft by hand, or see heat discolouration on the race. Once a bearing has spun, the shaft it sits on needs inspection too.

Ordering reference for the Crankshaft Thrust Washer is part number ft4z6337aa, categorised under Crankshafts & Bearings. Match that number against the component you are removing before you order.

This is FORD dealer-sourced stock rather than an equivalent, so the number on the Crankshaft Thrust Washer traces straight back to the manufacturer.
