2014 Mazda CX-5 Thrust Bearing — What It Is and When It Matters

For the 2014 Mazda CX-5, a thrust bearing is absolutely relevant and fitted. Mazda’s official Workshop Manual (Mazda Global Service Support, CX-5 2012–2016, Engine—Cylinder Block—Main Bearing) details crankshaft thrust bearing halves that control end float, and includes an end-play check procedure. Aftermarket catalogues from established bearing manufacturers (such as ACL and King Engine Bearings) also list crankshaft thrust bearings/thrust washers for the Skyactiv-G 2.0/2.5 and, in applicable markets, the Skyactiv-D 2.2—reinforcing that the part exists and is serviceable on this model.

On the 2014 CX-5, the thrust bearing lives in the engine block as part of the main bearing set. Its job is to control the crankshaft’s fore–aft movement when axial loads turn up—think clutch application on manual models, torque converter loads on autos, and even the gentle push–pull from accessory drive belts. Keeping that end float in check helps the crank trigger wheel line up properly with the sensor, keeps the oil pump and timing components happy, and prevents nasty wear on the crank cheeks and block.

It’s not a routine service item like filters or spark plugs. In normal use and with the right oil, a thrust bearing will generally last the life of the engine. That said, high kilometres, repeated heavy clutch loads, towing, or oil starvation can accelerate wear.

• Typical warning signs: shimmering metallic debris in the oil, a scraping or rubbing noise at idle when the clutch is pressed (manuals), erratic clutch engagement, or measurable crank pulley fore–aft movement.
• Good practice: stick to manufacturer-specified engine oil and intervals, avoid riding the clutch, and address any low oil pressure or misalignment issues promptly.

Replacement is a workshop job. The sump and main bearing cap(s) have to come off, thrust surfaces are inspected, and end float is measured with a dial indicator. If wear is found, technicians will fit the correct-grade thrust bearing halves (often paired with main bearings), verify clearances, and torque everything to spec from the Mazda workshop manual. Many shops will combine this with new seals and a close look at the oil pump and bearings while they’re already in there.

Owners who keep oil fresh and treat the driveline kindly rarely need to think about this part—but it’s good to know it’s there doing quietly critical work on every drive.

• Does the 2014 Mazda CX-5 have a thrust bearing?
  Yes. The crankshaft uses thrust bearing halves to control end float, as outlined in Mazda’s CX-5 Workshop Manual. Note this is different from the clutch release (throw-out) bearing or the front strut top bearing, which some people also call a “thrust” bearing.
• When should a thrust bearing be replaced on a 2014 CX-5?
  It isn’t a scheduled service item. Replacement happens during an engine rebuild, when end float is out of spec, or if there are symptoms like noise under clutch load (manuals) or metal particles in the oil.
• What symptoms point to a worn thrust bearing?
  Look for axial movement of the crank pulley, clutch engagement issues on manuals, scraping noises when depressing the clutch, poor idle with clutch in, or glitter in the oil. A technician will confirm by measuring crankshaft end float.
