Parts for your 2018 Honda Accord-Thrust bearing

2018 Honda Accord thrust-bearing: what it does and when it needs attention

On the 2018 Honda Accord, a thrust-bearing is indeed used. Honda’s factory service information for the 2018 Accord (Engine Mechanical section) and the Honda electronic parts catalogue specify crankshaft thrust bearing surfaces (thrust washers integrated with the main bearing set) across all engines, including the 1.5‑litre turbo, 2.0‑litre turbo and the hybrid. On models fitted with the 6‑speed manual, there’s also a clutch release bearing—often colloquially called a thrust bearing—in the clutch assembly. CVT, 10‑speed auto and hybrid e‑CVT variants don’t have a user‑serviceable driveline thrust bearing, but they still rely on internal thrust elements within the engine and transmission.

The engine’s thrust-bearing controls axial movement of the crankshaft (end float), keeping the rotating assembly centred under fore‑and‑aft loads from the clutch, accessory drives and transmission input. That prevents crank walk, reduces wear on the main bearings and helps maintain smooth, quiet operation. In manual models, the clutch release bearing lets the pressure plate disengage smoothly when the pedal’s pressed, cutting friction and noise.

As for servicing, the thrust-bearing isn’t a routine maintenance item. Engine thrust surfaces are inspected and measured for end float during engine repair or rebuild, not at scheduled services. However, manual‑transmission owners should always replace the clutch release bearing whenever the clutch is renewed—it’s standard best practice and avoids paying labour twice.

They should keep an ear out for common symptoms that warrant inspection:

• Manual: rumbling or squeal with the clutch pedal depressed, chatter on take‑off, a notchy pedal feel.
• Engine: a dull knock when the clutch is pushed, visible crank pulley movement fore‑aft, metal flakes in oil during services.

Good habits make a difference. Don’t ride the clutch, avoid aggressive clutch dumps, and stick to Honda’s specified oil grade and change intervals—clean, correct‑viscosity oil helps protect thrust faces. If any end‑float or release‑bearing noise is suspected, a technician can check crankshaft end play with a dial gauge against Honda’s spec and listen for release‑bearing noise during a road test. On manual cars, bundling a new release bearing with a clutch kit, pilot bearing/bushing and rear main seal is the smart, cost‑effective move. For CVT, 10‑speed auto and hybrid variants, any thrust‑related concern is internal and should be assessed by a transmission specialist using Honda procedures.

• Does the 2018 Honda Accord have a thrust-bearing?
  Yes. All engines use crankshaft thrust bearing surfaces, and manual models also have a clutch release (thrust) bearing. Auto, CVT and hybrid variants don’t have a serviceable external thrust bearing in the driveline.
• When should the thrust-bearing be replaced?
  Engine thrust bearings are replaced only if end float is out of spec during repair. On manual cars, replace the clutch release bearing whenever the clutch is replaced or if it’s noisy.
• What are signs of a failing thrust-bearing?
  Manual: noise with the clutch pedal depressed and a rough pedal feel. Engine: fore‑aft movement at the crank pulley, a knock when pressing the clutch, or metallic debris in the oil.
