Buying Drivetrain Parts for a 2003 Acura RL

On this vehicle, the drivetrain system moves power from transmission to wheels through axles, CV joints, driveshafts, differentials and wheel-end hardware.

  • Confirm you have the 3.5L V6 engine — every part on this page is matched to it.
  • Read the notes on each row for position, trim and spec qualifiers before you order.

Frequently Asked Questions

How many drivetrain parts fit the 2003 Acura RL?

Our catalog currently lists 41 drivetrain parts for the 2003 Acura RL across 5 subcategories and 20 brands, covering the 3.5L V6 engine. Each part is matched to the engine(s) it fits.

What are the signs of drivetrain problems on a 2003 Acura RL?

Common symptoms include clicking in tight turns, a clunk when shifting between drive and reverse, vibration that builds with speed, or gear oil on the inside of a wheel. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What should I replace at the same time?

Where labor overlaps, replace the differential or transfer-case fluid with any axle or seal job while everything is already open.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2003 Acura RL was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2003 Acura RL?

Every part on this page is matched to the 3.5L V6 engine. Then a torn CV boot caught early is a cheap boot kit; caught late it is a whole axle — inspect before deciding which to buy. The notes column carries position and trim qualifiers where they apply.
