Parts for your 2008 Mazda Cx-9-Thrust bearing

2008 Mazda CX-9 Thrust Bearing — Is it actually a thing on this model?

Short answer: a “thrust bearing” isn’t a relevant, serviceable part on the 2008 Mazda CX-9. Technical sources confirm the CX-9 was sold with a 6‑speed automatic transaxle (Aisin AW6A‑EL/TF‑81SC) and no manual gearbox. Because there’s no clutch, there’s no clutch thrust/release bearing to replace. References include: Mazda CX‑9 (2007–2015) Workshop Manual/New Model Features, Aisin AW TF‑81SC service information, and Ford/Mazda documentation for the 3.7‑litre MZI/Duratec 37 V6.

Here’s why the part doesn’t show up in normal servicing. In vehicles with a manual, the thrust (release) bearing sits on the clutch fork and presses the pressure plate fingers — a common wear item. The 2008 CX‑9 uses a torque converter, so that whole clutch assembly — and its thrust bearing — simply doesn’t exist. While the engine does have crankshaft thrust bearings (thrust washers) and the automatic transaxle has internal thrust/needle bearings, those are internal components handled only during major engine or transmission overhaul, not routine maintenance.

If someone’s chasing a “thrust bearing” noise on a CX‑9, it’s worth looking elsewhere. Common culprits that get mixed up with the term include:

• Front strut top mount bearings causing graunching or binding when turning.
• Front hub/wheel bearings humming that rises with road speed.
• Torque converter or internal transmission bearings if there’s a whine in specific gears.
• Accessory drive components (idler/tensioner pulleys, alternator, A/C compressor) for belt-area squeal or rumble.

For everyday servicing of a 2008 Mazda CX‑9 in Aus/NZ, a “thrust bearing” isn’t on the list. Instead, stick to scheduled items and address noises by proper diagnosis. If an internal engine or transmission thrust bearing problem is ever suspected (rare), that’s workshop-level inspection involving end‑float checks and, if confirmed, an engine/trans rebuild rather than a simple part swap.

• Popular questions about 2008 Mazda CX‑9 thrust-bearing

Does a 2008 Mazda CX‑9 have a clutch thrust bearing?
No. The CX‑9 came with a 6‑speed automatic only, so there’s no manual clutch and no clutch thrust/release bearing to service. Any “thrust bearing” listings you see usually apply to manual models in other vehicles, not this one.

What could be mistaken for a thrust bearing noise on a CX‑9?
Most commonly front strut top mount bearings, front hub/wheel bearings, or belt‑drive pulleys. Transmission or torque converter noises are less common but possible. A proper road test and stethoscope check usually pins it down quickly.

Are there thrust bearings inside the CX‑9 engine or transmission?
Yes, internally. The V6 uses crankshaft thrust bearings (washers), and the Aisin automatic has internal thrust/needle bearings. They’re not service items and are only addressed during engine/transmission overhaul if wear is confirmed.
