Parts for your 2018 Honda Odyssey-Universal joints

2018 Honda Odyssey universal joints — are they actually used?

Shoppers hunting for universal joints on a 2018 Honda Odyssey will come up empty for the driveline. That model is front‑wheel drive in Australia and New Zealand (and in North America), so it doesn’t use a rear propeller shaft or rear differential that would typically require universal joints. Instead, the Odyssey’s front half‑shafts use constant‑velocity (CV) joints at both ends.

Technical sources back this up: Honda’s service information for the 2018 Odyssey (RL6/RC series) lists front driveshafts with inner and outer CV joints and no propeller shaft assembly. OEM parts catalogues for the same model show front axle shafts with CV joints only, there’s no listing for driveline universal joints. Textbook references such as the Bosch Automotive Handbook explain why: traditional Hooke’s universal joints create cyclic speed variation at angle, while CV joints maintain constant rotational speed through larger steering angles, which is essential for modern FWD packaging and smoothness.

• Honda Service Information/Workshop Manual (2018 Odyssey): Driveline/Axle section specifies inner/outer CV joints, no prop shaft.
• Honda OEM parts catalogues for 2018 Odyssey: front driveshaft assemblies with CV joints, no driveline U‑joint part numbers.
• Bosch Automotive Handbook and standard drivetrain texts: FWD vehicles employ CV joints to allow large steering angles at constant velocity, single U‑joints introduce speed fluctuation and vibration.

Why universal joints aren’t used here comes down to geometry and refinement. In a front‑wheel‑drive minivan, the driveshafts must steer and move with the suspension while delivering smooth torque. CV joints handle big angles without the pulsating rotational speed that a single universal joint causes. That means better NVH, no shudder on lock, and longer tyre life. Because the Odyssey doesn’t have a rear driveshaft, there’s simply nowhere for a classic U‑joint to live in the driveline.

Worth noting: there are small universal joints in the steering intermediate shaft on many vehicles, and the Odyssey is no exception. Those are part of the steering column assembly and aren’t a routine service item. If someone’s chasing a clunk or a click under power in a 2018 Odyssey, the smart place to look is the CV joints and boots: check for split rubber boots, grease fling, and clicking on low‑speed turns. Fixes usually involve replacing the affected CV joint or the complete axle shaft, then torquing the hub nut to spec with a new stake nut.

If a parts search turns up “universal joints” for this model, it’s typically a catalogue mismatch. For driveline work on a 2018 Odyssey, ask for front CV axles, CV joints, or CV boots rather than U‑joints.

Popular questions

Does a 2018 Honda Odyssey have universal joints in the driveline?
No. It’s front‑wheel drive and uses CV joints on the front half‑shafts. There’s no rear prop shaft or differential, so no traditional driveline U‑joints are fitted.

What should be serviced instead of universal joints on a 2018 Odyssey?
Inspect the front CV joints and boots. Look for split boots, grease leaks, and clicking on full lock. Replace the damaged boot or the complete axle if wear is evident, and always use new hardware and correct torque.

Are there any universal joints on the Odyssey at all?
Only in the steering intermediate shaft. They’re part of the column/shaft assembly and not normally serviced separately. If the steering feels notchy or has play, the intermediate shaft assembly may need replacement.
