Parts for your 2004 Honda Elysion-Universal joints

2004 Honda Elysion universal joints: what’s fitted and what to service

Based on Honda’s technical literature for the Elysion (RR1–RR4) and the Honda Electronic Parts Catalogue, universal joints (U‑joints) are not used on front‑wheel‑drive Elysion models (RR1/RR3). Those variants use constant‑velocity (CV) joints on the front driveshafts only. However, the 4WD/AWD Elysion (RR2/RR4) includes a rear propeller shaft that employs universal joints to transmit drive to the rear differential. This layout is outlined in the Honda Elysion Factory Service Manual (Driveline/Axle) and the EPC listings that show a propeller shaft assembly for RR2/RR4.

Where fitted (RR2/RR4), universal joints sit on the propeller shaft to handle changes in angle and length as the body and rear differential move. They keep torque flowing smoothly from the transfer output at the transaxle to the rear diff under acceleration, cornering and over bumps. On this model, the prop shaft assembly is typically supplied with staked, sealed U‑joints from factory, meaning there are no grease nipples and Honda generally treats the joints as non‑serviceable items. In practice, many workshops inspect them routinely and, if wear is found, either replace the complete shaft or fit high‑quality replacement U‑joints and have the shaft rebalanced.

For servicing, a regular check every 20,000–40,000 km as part of underbody inspection is a smart move. Look for red dust around the caps (rust bleed), slung grease, notchy movement when the shaft is articulated by hand (with the vehicle safely raised and the driveline unloaded), and any looseness at the yokes. Also check the centre support bearing and the prop shaft’s rubber couplings if fitted. Road‑test clues include:

• Clunk when shifting from reverse to drive or on throttle lift‑off/take‑up
• Shudder on take‑off or vibration at steady speeds
• Rhythmic droning that changes with road speed, not engine rpm

If replacement is needed, mark the flanges to preserve phasing, follow torque specs from the Honda manual, and use new flange bolts where specified. If installing individual U‑joints, choose reputable, correct‑dimension parts and have the assembly balanced to avoid driveline vibration. After refit, a short highway run is useful to confirm the vibration is gone. Because these joints are sealed, there’s no periodic greasing, condition‑based inspection is the go.

For owners of FWD Elysions (RR1/RR3), universal joints aren’t present—focus instead on CV boots and joint play on the front driveshafts, as outlined in the same factory service documentation.

• Does a 2004 Honda Elysion have universal joints?
  FWD models (RR1/RR3) don’t—only CV joints up front. AWD/4WD models (RR2/RR4) do, on the rear propeller shaft connecting to the rear differential. Checking the chassis code or looking for a prop shaft under the vehicle will tell you which setup you’ve got.
• What are the signs of worn U‑joints on an Elysion?
  Common symptoms are a clunk on take‑up, a shudder on launch, or a speed‑related vibration. Underneath, look for rust dust at the caps, slung grease and any free play at the yokes. If in doubt, get a technician to inspect with the vehicle safely raised.
• Can the U‑joints be replaced separately, or is a full prop shaft needed?
  From factory they’re typically staked and supplied as a complete shaft. Many workshops either replace the whole assembly or fit quality replacement U‑joints and then rebalance the shaft. Local availability and condition of the existing shaft usually decide which path is most cost‑effective.
