Parts for your 2008 Honda Civic-Thrust bearing

2008 Honda Civic thrust-bearing

Relevant? Yes. The 2008 Honda Civic uses a crankshaft thrust bearing (thrust faces integrated with a main bearing) to control axial movement of the crank. This is documented in the Honda Civic 2006–2011 Service Manual under engine block/crankshaft end play checks, and it’s also called up in Honda’s parts catalogue as part of the main bearing set for R-series (1.8) and K-series (2.0) engines. Technical literature from bearing manufacturers (e.g., ACL/Clevite) explains that these thrust faces handle clutch and accessory-induced axial loads. So, a thrust-bearing is absolutely relevant on a 2008 Civic.

What does it do? The thrust-bearing prevents the crankshaft from walking forwards and backwards under load. Pressing the clutch on manual models, converter and pump loads on autos, and drive-belt forces all try to shove the crank axially. The thrust-bearing keeps that movement within a tiny window so the engine stays quiet, the oil pump and timing stay happy, and the clutch/flex-plate alignments remain spot-on.

Servicing advice for a 2008 Civic: there’s no routine replacement interval—these bearings generally last the life of the engine if oil quality and driving habits are reasonable. However, they should be inspected if there are symptoms like metallic rubbing noises when the clutch is depressed, the crank pulley shifting noticeably, stalling when the clutch is pressed, difficulty selecting gears, or measured end play outside spec during an engine repair. The Honda manual sets the measurement method with a dial gauge, compare the reading to the factory limits provided in that manual.

If replacement is needed, it’s an engine-bottom-end job: sump off, main cap(s) removed, and the thrust half-rings/bearing shell at the specified main journal replaced, then clearances rechecked. On Hondas, the thrust faces are typically at the centre main. Use the colour/grade the manual specifies, confirm oil clearance with plastigauge, and make sure the crank’s thrust surfaces aren’t scored. Always torque fasteners to spec and prime the oil system on restart.

Good habits help in AU/NZ conditions: avoid riding the clutch, don’t sit at lights with the pedal pushed in, keep engine oil fresh and at the correct grade, and address noisy accessories or misaligned belts promptly—these all reduce unnecessary thrust loading.

Does every 2008 Civic have a thrust-bearing?
Yes. Whether it’s the 1.8 R-series, the 2.0 K-series, manual or auto, the engine’s main bearing set includes thrust faces that control crank end play. It’s part of fundamental engine design and is covered in the Honda workshop manual and parts catalogue for this model range.

What are the signs of a worn thrust-bearing on a Civic?
Common clues include a scraping/rubbing sound when the clutch is depressed, the crank pulley moving in and out, clutch engagement issues, or the engine stumbling when the clutch is pushed. A proper check uses a dial gauge on the crank to confirm end play against the Honda spec.

Can the thrust-bearing be replaced with the engine in the car?
Sometimes, but it’s still a significant job. The sump must come off and the relevant main cap removed to access the thrust faces, then clearances measured and set. Many workshops prefer engine-out if other work is being done, as it speeds inspection and ensures a cleaner result.
