Parts for your 2018 Haval H6-Bump stops

2018 Haval H6 bump-stops: what they do and when to replace them

Technical references confirm the 2018 Haval H6 does use bump-stops (also called jounce bumpers). The H6 runs a MacPherson‑strut front and independent multi‑link rear suspension, as listed in manufacturer specs and common AU/NZ data sheets. In MacPherson struts, a microcellular‑urethane jounce bumper is an integral part of the strut assembly that limits compression and tunes NVH, this is well documented in SAE literature on jounce bumper design and in major damper makers’ service manuals (e.g., KYB/Monroe) describing strut bump-stop and dust-boot assemblies. Rear multi‑link layouts also employ bump rubbers on the damper or body to protect the suspension and bodywork. So, bump-stops are fitted and absolutely relevant on this model.

Bump-stops on a 2018 Haval H6 act as the last line of defence when the suspension compresses hard — over speed humps, potholes, corrugations, towing, or with a boot full of gear. The foam/urethane bumper cushions the final bit of travel so the strut or shock doesn’t hammer into its end cap or let control arms or tyres make unwanted contact. That saves bushings, keeps the tyre clear of the guard, and smooths out the hit so the cabin doesn’t cop a nasty thud.

On the H6 the front jounce bumper sits on the strut shaft under the dust boot, the rear uses a similar bump rubber on the damper or mounted to the body, depending on variant. They also help tune how the SUV feels at the limit — progressive bump-stops make the last bit of travel firmer, which steadies the body and helps stability with a caravan or when the car’s loaded.

They’re wear items. Heat, oil mist from a leaking damper, UV and road grime can crack or crumble the material. During regular servicing, it’s smart to have them inspected anytime the wheels are off — especially every 40–60,000 km, after harsh off‑bitumen trips, or when replacing shocks, struts or springs.

• Tell‑tales of tired bump-stops: a sharp bottoming‑out knock over big hits, harsher ride when loaded, and visible splits or missing chunks when the dust boot is pulled back.
• When doing fronts, the strut has to come out and be compressed safely — ideal time to renew the dust boot as they usually clip together.
• Replace in axle pairs, use quality microcellular urethane, and torque everything to spec. After front strut work, get a wheel alignment.

If a damper is oily, sort that first, a new bump-stop won’t last long bathed in fluid. DIY‑ers can handle many rear setups with stands and a torque wrench, but the front is often a workshop job due to spring compression risk. Parts are inexpensive, labour is what adds up, so bundle the job with new shocks/struts. While there, check strut top mounts, sway‑bar links and spring seats, as worn companions can mimic the same clunk. Look after them and the H6’s suspension stays quiet, controlled and ready for Aussie and Kiwi roads without any drama.

• Does the 2018 Haval H6 have bump-stops?
  Yes. The front MacPherson struts include a jounce bumper under the dust boot, and the independent rear suspension uses bump rubbers on the damper or body. They limit compression, protect components and smooth big hits.
• How often should H6 bump-stops be replaced?
  There’s no fixed interval. Inspect them at regular services and whenever shocks/struts are replaced. Replace if cracked, crumbling, oil‑soaked, missing, or when renewing dampers (commonly around 80–120,000 km depending on use).
• Is it safe to drive with worn bump-stops?
  Short term, the car may still drive, but there’s a higher risk of bottoming‑out, damage to shocks or mounts, and rough handling over big hits. Severely perished parts — especially alongside a leaking damper — can attract a fail at WOF/RWC time.
