Parts for your 2020 Haval H6-Universal joints

2020 Haval H6 universal joints — what’s fitted and how to look after them

Based on technical sources including the GWM/Haval H6 (2017–2020) workshop manual driveline section and GWM electronic parts catalogue listings for AWD variants, universal joints (cardan U‑joints) are used on the 2020 Haval H6 when it’s an all‑wheel drive. Those AWD models run a two‑piece propeller shaft with a centre support bearing and U‑joints to connect the gearbox/output coupling to the rear differential. Front drive shafts use constant‑velocity (CV) joints. On 2WD (front‑wheel drive) H6 models there’s no rear prop shaft, so no driveline universal joints are fitted.

For owners of the AWD 2020 H6, the universal joints let the prop shaft transmit torque while the suspension moves and the driveline runs at slight angles. They keep things smooth and quiet while coping with changes in length and angle across bumps and under load. Unlike the front CV joints, most prop shaft U‑joints on the H6 are sealed-for-life and, depending on market/part number, may be integrated with the shaft assembly rather than serviced separately.

As part of regular servicing, it’s smart to give the prop shaft and U‑joints a once‑over every 10–20,000 km or 12 months. A technician should check for play at the bearing caps, binding when the shaft is articulated by hand, cracked or missing dust seals at the caps, rust‑coloured dust, and any weeping of lubricant. They’ll also inspect the centre support bearing and confirm the prop shaft bolts are tight to spec. If grease nipples are present (uncommon on late‑model OE shafts), a light pump with the specified grease until fresh grease appears at the seals is the go—don’t overdo it.

• Typical warning signs: a dull clunk on take‑up, vibration that rises with road speed, chirping/creaking at low speed, or visible play in a joint.
• Replacement tips: mark the yoke positions before removal to preserve phasing, keep the shaft balanced, and follow torque specs from the H6 workshop manual. Many H6 AWDs use staked or non‑serviceable joints—if so, replace the complete prop shaft assembly.

If your 2020 Haval H6 is 2WD, universal joints simply aren’t part of the picture—the front axles use CV joints only. If it’s AWD, keeping an eye on the U‑joints during routine servicing helps prevent driveline shudders and protects the rear diff and coupling from unnecessary stress.

Popular questions

How do I know if my 2020 Haval H6 actually has universal joints?
If it’s the AWD model, it does—there’ll be a propeller shaft running from the front to the rear diff with U‑joints at the ends. If it’s 2WD (front‑wheel drive), there’s no rear prop shaft, so no driveline U‑joints fitted. Your build plate, owner’s handbook, or a quick look under the vehicle will confirm it.

Can the H6’s universal joints be replaced on their own?
On many 2020 H6 AWDs, the OE prop shaft uses non‑serviceable (staked) joints, so the recommended repair is a complete prop shaft assembly. Some aftermarket options may offer serviceable U‑joints, but always check your parts catalogue by VIN and follow workshop manual guidance to avoid balance and phasing issues.

How often should the universal joints be serviced?
They’re generally sealed-for-life, so there’s no scheduled greasing on OE shafts. Still, inspection every service (or at least every 10–20,000 km) is wise—catching play, noise or vibration early will save the centre bearing and rear diff coupling from copping it later.
