Parts for your 2008 Ford Mondeo-Thrust bearing

2008 Ford Mondeo thrust bearing — what’s fitted and how to look after it

Based on Ford technical literature for the Mondeo Mk4 (CD345, 2007.5–2010), a thrust-type bearing is fitted on manual-transmission models as the clutch release bearing, integrated with the concentric slave cylinder (CSC). This is detailed in the Ford Workshop Manual, section 308-02 (Clutch) for MTX-75/MMT6 gearboxes, which specifies a hydraulic CSC with an integral release/thrust bearing. Haynes Mondeo 2007–2012 and OE parts catalogues for CD345 models also list the CSC/release bearing as a service part. Automatic variants don’t have a clutch thrust bearing, though all engines still use crankshaft thrust bearings inside the main bearing set (Ford Workshop Manual 303-01 Engine).

On a 2008 Ford Mondeo with a manual gearbox, the thrust bearing’s job is to transfer pedal effort to the clutch spring smoothly and quietly. Because it’s built into the CSC, it sits around the gearbox input shaft and pushes directly on the pressure plate diaphragm. That design gives a lighter, more consistent pedal feel and helps reduce vibration through the driveline.

There’s no calendar or kilometre-based replacement interval for the CSC/release bearing, it’s replaced on condition. The smart play during a clutch job is to renew the CSC at the same time. Labour overlaps heavily, and a fresh bearing alongside a new friction disc and pressure plate avoids paying to pull the gearbox again. While there, it’s worth inspecting the dual-mass flywheel for excessive play or heat spots and replacing flywheel bolts if specified single-use in the workshop manual.

• Typical wear signs: a chirp or whirr that changes when the clutch pedal is pressed, a notchy or pulsing pedal, fluid weeping from the bellhousing, or difficulty selecting gears at a standstill.
• Service tips: always use the correct DOT 4 brake fluid for the shared clutch/brake reservoir, follow the Ford bleed procedure to avoid aeration, and keep the bellhousing scrupulously clean during assembly.
• What about autos? No clutch thrust bearing on torque-converter autos. The engine’s crankshaft thrust bearings are internal and only checked/replaced during engine repair if end-float is out of spec.

Parts quality matters here. OE or reputable aftermarket kits (often supplied as a matched clutch, CSC, and alignment tool) help ensure the new bearing runs quiet and true. A technician with the Mondeo CD345 procedures to hand will also check clutch hydraulic line seals, guide the gearbox in straight to protect the CSC, and verify end-float and DMF condition before buttoning up.

Popular questions about 2008 Ford Mondeo thrust bearings

Does every 2008 Mondeo have a thrust bearing?
Manual models do, as the clutch release bearing is integrated with the concentric slave cylinder. Automatic versions don’t have a clutch thrust bearing, but the engine still uses internal crankshaft thrust bearings that aren’t routine service items.

When should the thrust (release) bearing be replaced?
Replace it whenever the clutch is renewed, or if there’s noise when the pedal is pressed, hydraulic fluid leaks from the bellhousing, a spongy pedal that won’t bleed out, or poor disengagement. It’s cost-effective to do the CSC with the clutch because the gearbox has to come out either way.

What else should be checked during a thrust bearing job?
Inspect the dual-mass flywheel for excessive rock or blueing, renew single-use bolts if the manual calls for it, and flush/bleed the hydraulic system with the correct DOT 4 fluid. A careful clean of the bellhousing and correct alignment helps the new bearing live a long, quiet life.
