Parts for your 2009 Ford Mondeo-Thrust bearing

2009 Ford Mondeo thrust-bearing: what it does, when it’s fitted, and how to look after it

Based on Ford technical sources — the Ford Mondeo 2007–2014 Workshop Manual (TIS) and the Ford parts catalogue listings for MTX75/MMT6 gearboxes — a thrust-bearing (better known as the clutch release bearing, and integrated into a concentric slave cylinder) is fitted to 2009 Ford Mondeo models with a manual transmission. The Aisin six‑speed automatic (TF‑80SC/AWF21) uses a torque converter, so it does not have a clutch thrust-bearing. The engines themselves do have crankshaft thrust bearings inside the bottom end, but those aren’t routine service items and aren’t what’s meant by a serviceable “thrust-bearing” on this model.

On manual 2009 Mondeos, the thrust-bearing’s job is to press smoothly on the pressure plate’s diaphragm spring while spinning at engine speed, letting the clutch disengage cleanly when the pedal’s pressed. Because it’s built into the hydraulic concentric slave cylinder (CSC) inside the bellhousing, it’s working every time the clutch is used — so smooth, quiet operation matters for pedal feel and gearbox longevity.

Typical tell‑tales of a worn thrust-bearing include:

• Whirring, chirping, or grinding noise that changes when the clutch pedal is pressed
• Notchy or heavy clutch action, poor disengagement, or difficulty selecting gears
• Fluid contamination around the bellhousing (from a leaking CSC)

Best practice during servicing:

• Replace the thrust-bearing/CSC whenever the clutch is replaced — the gearbox is already out, so it’s smart money.
• Use quality OEM‑spec parts and renew the CSC O‑rings/seals. Cheap units can be noisy or leak.
• Inspect the dual‑mass flywheel for play, heat spots, or oil contamination, replace if out of spec.
• Flush and bleed the clutch hydraulics with the correct brake fluid (DOT 4, as specified by Ford).
• Check the gearbox input shaft and guide tube for wear, a scored tube will chew up a new bearing.
• Avoid riding the clutch, keep the pedal fully up when cruising to spare the bearing from needless load.

There’s no set kilometre interval for the thrust-bearing — it’s condition‑based. If there’s noise with the pedal depressed, a sinking pedal, or fluid loss, it’s time for inspection. For automatic Mondeos, this part isn’t relevant because the torque converter handles launch and there’s no manual clutch release mechanism to service.

Popular questions

How can someone tell if their 2009 Mondeo’s thrust-bearing is failing?
Listen for noise that appears or changes when the clutch pedal is pressed — especially whirring, chirping, or grinding. A heavier pedal, clutch drag, or hard gear changes also point to a tired bearing or a leaking CSC. Any fluid around the bellhousing is another red flag.

Does a 2009 Mondeo automatic have a thrust-bearing?
No. The six‑speed auto uses a torque converter, so there’s no clutch release/thrust-bearing to service. The engine’s internal crankshaft thrust bearings exist but aren’t routine service items.

Should the thrust-bearing be replaced with the clutch?
Yes. On the manual Mondeo the thrust-bearing is part of the CSC inside the bellhousing. Replacing it with the clutch saves labour later and helps ensure quiet, smooth operation after the job.
