Parts for your 2018 Nissan X-trail-Thrust bearing

2018 Nissan X‑TRAIL thrust bearing: what it does and when to worry

Based on the Nissan X‑TRAIL (T32) Factory Service Manual (2017–2019) — particularly the Engine Mechanical (EM) and Clutch (CL) sections — and the Nissan Electronic Parts Catalogue (FAST), the 2018 X‑TRAIL is fitted with a crankshaft thrust bearing as part of the engine’s main bearing set. This thrust bearing controls crankshaft endfloat in all petrol and diesel variants. For models with a manual gearbox, there’s also a clutch release bearing (often casually called a “thrust bearing”), CVT (Xtronic) models don’t use a clutch release bearing, though the CVT contains internal thrust/axial bearings that aren’t routine service items. JATCO Xtronic (JF016E/JF017E) service literature supports this distinction.

In the engine, the thrust bearing’s job is simple but crucial: it keeps the crankshaft from walking forwards and backwards under axial loads. Think clutch engagement on manuals, converter/CVT axial forces on autos, and accessory loads. It’s usually integrated into a specific main bearing shell with flanges or separate thrust washers. When it wears, endfloat grows — that can show up as odd noises, changes in clutch pedal feel (manuals), crank pulley creeping fore/aft under the bonnet, or premature rear main seal leaks.

This isn’t a routine service item like a filter. Workshops check thrust clearance if there are symptoms, during clutch work (manuals), or any time the sump is off or the engine’s out. Proper engine oil, regular changes, and avoiding riding the clutch (manual) all help the thrust face live a long life. If endfloat is out of spec, the fix is engine-bottom-end work: main bearing cap removal, selecting the correct bearing grade, and re‑measuring to the factory spec with a dial gauge. It’s specialist gear and know‑how, so most owners will want a trusted engine builder or Nissan dealer handling it.

• Watch for metallic scrape/whirr that changes with clutch pedal movement (manuals).
• Look for rear main seal weep and unusual crank pulley shift.
• If replacing, use quality bearings, check crank thrust faces for scoring, and renew fasteners and seals as specified in the FSM.

For manual X‑TRAILs, the clutch release (thrust) bearing is a wear item — if it growls when the pedal’s down, it’s time. Best practice is to replace it with the clutch kit and inspect crank endfloat while you’re there. CVT owners can relax: there’s no external clutch thrust bearing to service.

Popular questions

Does a 2018 X‑TRAIL with CVT have a thrust bearing?
Yes — in the engine. Every 2018 X‑TRAIL has a crankshaft thrust bearing. CVT models don’t have a clutch release (thrust) bearing like manuals do, and the CVT’s internal thrust bearings aren’t serviced during normal maintenance.

What are the signs a thrust bearing is worn?
Think growing crank endfloat: a change in clutch pedal feel or a rattle/whirr when the pedal’s pressed (manuals), visible fore‑aft movement of the crank pulley, or rear main seal leaks. A workshop can confirm with a dial gauge against the factory spec.

How much does thrust bearing replacement cost?
Engine thrust bearing replacement is a bottom‑end job, so budget for several hours of labour plus parts, costs vary widely with what’s found (bearing grades, crankface condition, seals/bolts). The clutch release bearing on a manual is far cheaper and typically done with a clutch kit.
