Parts for your 2006 Honda Stream-Universal joints

2006 Honda Stream universal joints: what’s fitted and what’s not

Based on Honda’s factory service manuals for the Stream (RN1–RN5, and early RN6–RN9) and the Honda Electronic Parts Catalogue, a typical 2006 Honda Stream with front-wheel drive does not use universal joints (U‑joints) in its front driveline. Instead, it runs constant velocity (CV) joints on the left and right driveshafts. That’s because the Stream is fundamentally a transverse-engine, front-drive MPV derived from the Civic platform, and CV joints are the correct joint type for steering and suspension travel at greater angles.

There is an exception. Certain Japan‑market 4WD variants (e.g., RN4/RN5 in the first generation and selected second-gen trims) use Honda’s Real Time 4WD system. Those versions add a propeller shaft to the rear differential, and that prop shaft employs universal joints. Honda’s workshop manual sections for Propeller Shaft/Rear Differential, along with the parts listings, show U‑joints on those 4WD assemblies, while the front axles remain CV‑jointed across all trims.

Why most 2006 Streams won’t have U‑joints comes down to driveline design. CV joints maintain constant rotational speed through large angles (ideal for steering), while classic U‑joints create speed fluctuation at higher angles, which would cause vibration and torque ripple in a front-drive, front‑steer setup. Hence Honda specifies CV joints at the front hubs for smoothness, durability and NVH control.

• For front-wheel drive Streams: there are no serviceable U‑joints. Focus routine servicing on CV boots (look for splits/grease sling), driveshaft play, engine/gearbox mounts and wheel bearings. Clicking on full lock under acceleration points to an outer CV joint, not a U‑joint.
• For 4WD Streams: a prop shaft with U‑joints is fitted. Typical U‑joint issues show as a clunk on take‑off or a speed‑related vibration. Many Honda prop shafts use staked, non‑greasable joints, workshop guidance often calls for prop shaft or joint replacement rather than greasing.

FAQs

Does a 2006 Honda Stream have universal joints?
Most 2006 Streams are front-wheel drive and do not have U‑joints in the front axles, they use CV joints. However, Japan‑market 4WD variants run a rear propeller shaft that does use U‑joints.

How can someone tell if their Stream has U‑joints?
Check underneath for a long propeller shaft running to a rear differential “pumpkin”. If that’s present, it’s a 4WD model with U‑joints. The build plate/owner’s manual may also note 4WD/Real Time 4WD. If there’s no rear diff or prop shaft, it’s front‑wheel drive with no U‑joints to service.

What noises point to U‑joint trouble versus CV joint wear?
A failing U‑joint typically causes a dull clunk when shifting from drive to reverse or a steady vibration that increases with road speed. A worn CV joint more often clicks or chatters on tight turns under throttle. Front‑drive Streams usually show CV symptoms, 4WD Streams can show either, depending on which joint is tired.
