Parts for your 2021 Honda Odyssey-Universal joints

2021 Honda Odyssey universal joints — are they used?

Short answer: universal joints (U‑joints) aren’t a driveline service item on the 2021 Honda Odyssey. Technical references show the Odyssey is front‑wheel drive only and uses constant‑velocity (CV) joints on its front driveshafts, not U‑joints. Honda’s 2021 Odyssey specifications list front‑wheel drive, the Honda Service Information for the 5th‑gen Odyssey (2018–2023) details Rzeppa‑type CV joints in Driveline/Axle — Front Driveshaft with no propeller shaft noted, and common parts catalogues for this model carry CV shafts/boots but no propeller‑shaft U‑joint listings. That combo tells the story: there’s no rear diff or longitudinal driveshaft, so the typical U‑jointed shaft simply doesn’t exist on this people mover.

Why isn’t a U‑joint used here? In a transverse, front‑wheel‑drive layout the job is handled by CV joints, which maintain constant angular velocity through larger steering and suspension angles. A cross‑type U‑joint, great for longitudinal prop shafts in rear‑ or all‑wheel drive vehicles, introduces speed fluctuation at angle and needs a matching joint to cancel it out. It’s not ideal for front drive half‑shafts that must steer and articulate, so Honda specifies CVs instead.

Where a U‑joint does appear is in the steering intermediate shaft. It’s a small cross‑joint that lets the column angle down to the rack. Honda treats that piece as an assembly — if there’s play, stiffness, corrosion, or a notchy feel at the wheel, the fix is replacement of the intermediate shaft rather than greasing or pressing in a separate U‑joint. This aligns with the service manual’s approach to the steering column/shaft components.

Servicing advice for owners: don’t go hunting for grease nipples or replaceable driveline U‑joints on a 2021 Odyssey — there aren’t any. Instead, keep an eye on CV boots for splits or grease fling, listen for clicking on full‑lock turns (classic worn CV noise), and monitor vibration under load that can hint at inner CV wear. For the steering shaft U‑joint, pay attention to stiff spots, binding after water ingress, or rust at the firewall area, if present, have the intermediate shaft inspected and replaced as a unit. Using quality CV boots and timely replacement when damaged will save the CVs themselves, and proper wheel alignment and tyre condition will keep loads on the joints sensible.

• Driveline: CV joints only, no prop shaft U‑joints.
• Steering: contains a small U‑joint within the intermediate shaft assembly.
• Service focus: CV boots/shafts and, if needed, the steering intermediate shaft assembly.

Popular questions

Does a 2021 Honda Odyssey have universal joints in the driveline?
No. The 2021 Odyssey is front‑wheel drive and uses CV joints on the front half‑shafts. There’s no rear differential or propeller shaft, so there are no driveline U‑joints to service.

Is there any universal joint on a 2021 Odyssey at all?
Yes — in the steering intermediate shaft. If it develops play, binding, or rust, the usual fix is replacing the intermediate shaft assembly rather than servicing the joint by itself.

What symptoms point to CV joint issues rather than U‑joint problems on this model?
Clicking on tight turns, torn CV boots with grease flung around the inner wheel, or vibration on acceleration are classic CV signs. Traditional U‑joint clunks or shudders from a prop shaft don’t apply to the Odyssey’s driveline.
