Parts for your 1998 Daihatsu Gran move-Bump stops

1998 Daihatsu Gran Move bump-stops

Yes, the 1998 Daihatsu Gran Move is fitted with bump-stops. This is shown in Daihatsu’s own workshop literature for the Pyzar/Gran Move (suspension section), which calls them “bound bumpers” on the front MacPherson struts and bump rubbers on the rear dampers. The Daihatsu electronic parts catalogue used by ANZ dealers lists these components in the front spring/strut and rear shock assemblies, and major aftermarket catalogues (e.g., KYB and Monroe protection kits) also specify bump-stop and boot sets for this model.

On the Gran Move, bump-stops act like a last line of defence for the suspension. When the car hits a big pothole, speed hump or carries a heavy load, these dense foam rubbers step in before the strut or shock bottoms out. That saves the damper internals, protects the upper mounts and towers, and keeps the car feeling stable rather than crashing through its travel. They also add a bit of progressive spring rate right at the end of the stroke, so the transition from normal travel to full compression is more controlled and less jarring for passengers.

As with any rubber component in Aussie and Kiwi conditions, bump-stops age. Heat, UV, and road grime cause them to harden, crack, or crumble. Once they’re perished or missing, the Gran Move can thump over big hits, feel harsh with a full boot, and start chewing through strut mounts or shocks sooner than it should.

Best practice is to inspect the bump-stops whenever the shocks/struts are checked—ideally at each major service or around every 20,000–30,000 kilometres. Replacement is straightforward for a workshop: the fronts require strut removal (so it’s a good time to assess strut mounts and dust boots), and an alignment is recommended after refit. The rears are typically replaced with the shocks. Choose OE-style microcellular foam stops and new dust boots, swapping them in pairs keeps the ride consistent left-to-right.

Signs your Gran Move may need fresh bump-stops:

• Sharp “bang” or clunk over speed humps or deep potholes
• Perished, split, or missing bump rubbers or boots on inspection
• Frequent bottoming with passengers, cargo, or a trailer

They don’t cost the earth, they protect pricier suspension parts, and they help the Gran Move keep its easy-going ride—well worth doing before the next WOF or rego check.

Popular questions

Does the 1998 Daihatsu Gran Move have front and rear bump-stops?
Yes. The front MacPherson struts use bound bumpers, and the rear shock absorbers have bump rubbers. Both are serviceable items and should be checked with the boots.

Can bump-stops be replaced without changing the shocks?
They can. If the dampers test fine but the stops or boots are perished, a workshop can replace the protection kit. On the front, the strut still needs to come out, so many owners combine it with mounts or damper replacement to save labour.

What happens if bump-stops are missing or damaged?
You’ll feel harsher impacts and may hear a solid thud on big compressions. Over time, bottoming can damage strut mounts, towers, or the shock itself, and the car may feel less settled over rough roads.
