Parts for your 2007 Ford Focus-Thrust bearing

2007 Ford Focus thrust-bearing: what it does and when to sort it

Based on Ford workshop information (TIS/ETIS), the Haynes Ford Focus 2005–2011 manual, and OE parts catalogues, the 2007 Ford Focus with a manual gearbox uses a clutch release bearing (commonly called a thrust bearing). On models with the IB5 gearbox (typical on 1.4/1.6), it’s a separate release bearing operated by an external slave cylinder and fork. On models with the MTX-75 (common on 2.0), the thrust bearing is integrated into a concentric slave cylinder (CSC) inside the bellhousing. Automatic variants don’t have a serviceable clutch thrust bearing, so the term doesn’t apply to those.

On a manual 2007 Ford Focus, the thrust bearing’s job is simple but crucial: it transfers pedal effort to the clutch diaphragm spring so the gearbox can disengage cleanly. When the pedal is pressed, the bearing runs against the spring fingers, allowing the engine and transmission to spin independently for smooth shifting and stopping at lights without stalling.

Because it operates only when the pedal is down, the bearing can last a long time, but it does wear. Typical early warnings include a light whirring or chirp with the clutch pedal depressed, a rumble right at the bite point, or a noise that disappears as soon as the pedal is released. On MTX-75 cars, any fluid misting from the bellhousing can also point to a leaking concentric slave/release bearing.

There’s no fixed service interval for the thrust bearing. The best practice is to replace it whenever the clutch is out. Labour overlaps heavily with clutch work, so it’s false economy to refit an old bearing. For IB5 setups, a new release bearing, a clean guide tube, and a light smear of the correct high-temp grease on the fork pivot are smart moves. For MTX-75, the CSC and its O-rings should be renewed, the clutch hydraulics flushed with fresh DOT 4, and the system bled carefully to a firm, consistent pedal.

Quality parts matter. Mixing a new clutch with a bargain-bin bearing can bring the gearbox back out sooner than anyone would like. While in there, it’s wise to inspect the pressure plate fingers for uneven wear, check the input shaft seal for leaks, and verify the flywheel surface is clean and flat. Driving habits help too: avoiding resting a foot on the pedal and not holding the car on the clutch will keep the thrust bearing happier for more kilometres.

• Signs it’s crook: noise with pedal down, rough engagement, fluid weep (CSC models)
• Best time to replace: whenever the clutch is replaced or the box is out
• Good add-ons: new clutch kit, guide tube check, hydraulic flush (CSC)

Popular questions

How can a driver tell if the thrust bearing is failing on a 2007 Ford Focus?
The car may make a light whirring, chirp, or growl when the clutch pedal is pressed, which often fades when it’s released. A rough or notchy feel at the bite point can also point to bearing wear. If the vehicle has an MTX-75 gearbox, any clutch fluid drip or misting from the bellhousing suggests the concentric slave/release bearing is leaking.

Do all 2007 Ford Focus models use a concentric slave cylinder?
No. Many 2.0-litre cars with the MTX-75 use an internal concentric slave/release bearing. Smaller engines with the IB5 typically use an external slave cylinder, fork, and a separate release (thrust) bearing. Checking the VIN/gearbox code or a reputable parts catalogue will confirm which system a particular car has.

Is it sensible to replace only the thrust bearing without changing the clutch?
It can be done, but it’s usually not recommended. Because the gearbox has to come out, most workshops fit a complete clutch kit and the bearing together. That approach reduces the chance of pulling the box again soon for a worn disc or pressure plate.
