Parts for your 2017 Haval H6-Universal joints

2017 Haval H6 universal-joints

Based on manufacturer workshop literature and common driveline layouts documented for the Haval H6 (2017) — including the H6 Service/Workshop Manual driveline section, Great Wall Motors/Haval electronic parts catalogues for the propeller shaft assembly, and technical notes on on-demand AWD systems from BorgWarner used by many compact SUVs — universal joints (U‑joints) are fitted to H6 models equipped with all-wheel drive because they use a propeller shaft to drive the rear differential. Front‑wheel drive H6 variants do not have a propeller shaft and therefore do not use U‑joints, relying instead on constant‑velocity (CV) joints on the front half‑shafts.

On AWD 2017 Haval H6s, the U‑joints sit at the ends of the propeller shaft (and sometimes at an intermediate joint if a two‑piece shaft with a centre bearing is used). Their job is to let the shaft transmit torque while coping with the angle changes between the transmission’s power take‑off and the rear differential as the body and suspension move. This keeps things smooth, limits vibration, and protects bearings and seals throughout the driveline.

Servicing is pretty straightforward. Most factory H6 prop shafts use sealed, non‑greasable U‑joints, so there’s no routine greasing — inspection is the go. During scheduled servicing (or any time there’s a driveline vibration complaint), a tech should check for red dust marks around the bearing caps, dried sling marks, cracked seals, binding when the joint is articulated by hand, and any free play. If play or roughness is found, replacement is the fix. On many H6 assemblies the U‑joint is staked or integrated, that often means replacing the whole prop shaft or yoke assembly rather than pressing in a standalone cross.

Left too long, a flogged U‑joint can cause shudder under load, a chirp or clunk on take‑off, and premature centre bearing or differential seal wear. If the prop shaft is removed, mark the flanges and refit in the same orientation to preserve balance. After replacement, a quick road test for vibration at 60–100 km/h is wise.

• Tell‑tale symptoms: clunk on gear changes, vibration with speed, or a rhythmic squeak that rises with road speed.
• Good practice: inspect at every major service or after off‑road/water crossings.
• If in doubt: have a driveline specialist check runout and balance.

FAQs

Do all 2017 Haval H6 models have universal joints?
Not all. Front‑wheel drive variants don’t need a prop shaft and use CV joints only, so there are no U‑joints. AWD versions have a propeller shaft to the rear diff and use U‑joints (and a centre bearing on some specs).

What are the signs the H6 universal joints need replacing?
Common clues include a clunk on take‑off or when shifting from reverse to drive, a speed‑related vibration, or a squeak that follows road speed. Visual checks may show rust‑coloured dust at the caps, split seals, or looseness when the joint is moved by hand.

Are the H6’s U‑joints serviceable or sealed?
Most OEM assemblies are sealed for life without grease nipples. When wear is found, the joint is typically replaced — and on some shafts the entire prop shaft is swapped if the joints are staked or integrated.
