acura tsx 2005 parts
Key Takeaways
- The 2005 Acura TSX (CL9 chassis) shares many components with the European Honda Accord (CL7/CL8) and 2004–2008 TSX models, expanding sourcing options.
- Critical wear items — front control arm bushings, rear trailing arm bushings, VTC actuator, and automatic transmission torque converter — have known failure patterns that warrant proactive replacement.
- OEM part numbers are cross-referenced below; aftermarket brands like Beck/Arnley, Moog, Aisin, and RockAuto house brands offer reliable cost savings for non-critical components.
- VIN-specific lookup (positions 10–17) is essential for engine (K24A2), transmission (5AT vs 6MT), and ABS module variations.
- Retain receipts and install dates for warranty claims; many suppliers honor 12–24 month warranties on suspension and drivetrain parts.
Core Pain Points & Solutions
Suspension & Steering Wear
The 2005 TSX’s double-wishbone front suspension delivers sharp handling but accelerates bushing degradation. Owners report clunking over bumps, vague steering, and uneven tire wear as early as 60,000 miles.
- Front lower control arm bushings (OEM 51350-SDA-A01 / 51360-SDA-A01): Press-in design; replace arms complete (Moog RK80502 / RK80503) to avoid press labor.
- Front upper ball joints: Non-serviceable on OEM arms; aftermarket arms (Mevotech MK80502) include greaseable joints.
- Rear trailing arm bushings (OEM 52390-SDA-A01): Cause rear toe drift; upgrade to Energy Suspension 4.3131G polyurethane for track use.
- Outer tie rod ends (OEM 53540-SDA-A01): Inspect boot integrity at every oil change; Moog ES3479 is a direct fit.
Engine & Drivetrain Reliability
The K24A2 2.4L i-VTEC is robust but has well-documented weak points.
- VTC actuator rattle on cold start (OEM 14310-RAA-A01): Updated part (14310-RAA-A02) resolves oil drain-back; replace with timing chain service at 105k miles.
- Automatic transmission torque converter shudder (5AT): Fluid change (DW-1, 3.0 qt drain/refill every 30k) mitigates; severe cases require reman unit (OEM 28200-PPA-003).
- Manual transmission 3rd gear synchro wear (6MT): Honda MTF change at 30k intervals; Acura 08798-9031 fluid spec.
- Power steering pump whine: Use genuine Honda PSF (08206-9002); aftermarket fluids degrade seals.
Electrical & Electronics
- Driver’s door lock actuator (OEM 72150-SDA-A01): Fails ~90k miles; internal microswitch fatigues. Dorman 749-001 is a validated aftermarket alternative.
- HandsFreeLink (HFL) module battery drain: Unplug module (passenger kick panel) if not used; parasitic draw ~0.35A.
- Clock spring (OEM 77950-SDA-A01): Airbag light + cruise control loss; replace with steering wheel removal.
