Parts for your 2018 Honda Civic-Thrust bearing

2018 Honda Civic thrust bearing — what it is, where it lives, and when to sort it

Based on Honda’s 2016–2021 Civic Service Manual and the Honda electronic parts catalogue, a thrust bearing is absolutely relevant on the 2018 Honda Civic. Every Civic engine uses crankshaft thrust bearings (integrated into the main bearing set) to control end-float, and 6‑speed manual models (including Si and Type R) also use a clutch release bearing, commonly called a thrust or throwout bearing, in the clutch assembly. CVT-equipped Civics don’t have an external clutch thrust bearing, though the transmission contains internal thrust bearings that aren’t routine service items.

On the engine side, the thrust bearing’s job is to keep the crankshaft from walking back and forth under axial loads — think clutch engagement (on manuals), accessory drive forces, or torque converter/CVT axial loads. It holds crank end-float within tight spec so the crank stays centred and the oil film stays happy. On manual cars, the clutch release (thrust) bearing sits on the gearbox input shaft and pushes on the pressure plate fingers when the pedal’s pressed, letting the clutch disengage smoothly and quietly.

Servicing pointers vary by transmission type. For manual Civics, the release bearing is a wear item: replace it whenever the clutch is out. Most quality clutch kits include a new bearing, and that’s the go-to approach recommended by clutch suppliers and the Honda manual/transmission sections. If you’re chasing noises, a chirp or growl that changes when the clutch pedal is pressed often points to a tired release bearing. It isn’t lubricated externally, if it’s noisy or rough, don’t try to grease it — replace it.

Engine thrust bearings aren’t a periodic service part, but clean oil and proper clutch/drive technique protect them. During major engine work, a tech will measure crank end-float and inspect the thrust faces as outlined in the Engine Block/Crankshaft chapter of the Honda manual. Excessive end-float, metallic glitter in oil, or clutch-related axial loads (riding the clutch) can accelerate wear.

For CVT Civics, there’s no external clutch thrust bearing to replace. Any thrust bearings inside the CVT are part of the unit’s internal architecture and only addressed during a professional overhaul. Routine CVT servicing (fluid changes using the specified CVT fluid) helps protect those internal bearings.

• Manual models: replace the clutch release (thrust) bearing with the clutch, inspect fork/pivot, and check input shaft sleeve for wear.
• All models: use the specified engine oil and change on time, investigate end-float/noise concerns promptly.

Popular questions about 2018 Honda Civic thrust bearings

Does my 2018 Civic with a CVT have a thrust bearing I can service?

Not as a standalone part. CVT cars don’t use an external clutch release (thrust) bearing. Any thrust bearings live inside the transmission and aren’t serviced separately. Stick to the correct CVT fluid and intervals to help protect internal components.

When should the clutch release (thrust) bearing be replaced on a manual 2018 Civic?

Replace it whenever the clutch is out — it’s best practice and aligns with service manual guidance. If you notice a squeal, chirp, or rumble that changes when pressing the clutch pedal, plan a clutch job with a new bearing, pressure plate, and disc.

What are signs of engine thrust bearing issues on a 2018 Civic?

It’s uncommon, but symptoms can include noticeable fore–aft crank pulley movement, abnormal noises with clutch engagement (manuals), or metallic debris in oil. Diagnosis involves checking crank end-float against the spec in the Honda Service Manual.
