Parts for your 1997 Daihatsu Gran move-Bump stops

1997 Daihatsu Gran Move bump-stops

Yes, the 1997 Daihatsu Gran Move (G300-series, also sold as the Pyzar) is fitted with bump-stops. Daihatsu’s workshop manual for the G300 front suspension shows a “bump rubber” on the MacPherson strut assembly, and the rear suspension section specifies a body-mounted rear axle bump stop. The Daihatsu electronic parts catalogue for G30# models also lists front strut bump rubbers and rear bump stops as service parts, confirming they’re standard equipment.

The Gran Move’s bump-stops do an unsung but vital job. They act as progressive cushions that prevent the suspension from bottoming out under heavy loads, big potholes, or sudden hits. Up front, each strut carries a jounce bumper (bump-stop) hidden inside the dust boot on the damper rod. At the rear, a compact rubber block sits on the body above the axle beam. When the suspension reaches the end of its travel, these stops add a rising spring rate, protecting shocks, struts, mounts, and even the body shell from harsh metal-to-metal contact.

On a 1997 Gran Move that’s spent years dealing with Kiwi backroads or Aussie country kilometres, the original foam or polyurethane bump-stops can crack, crumble, or oil-soak and soften. The giveaway signs are a hard thud over big dips, sudden bottoming with passengers or cargo, or a new clunk where the stop has perished. Tyre rub on full compression, torn dust boots, and leaking struts are often travelling companions to failed bump-stops.

As part of routine servicing, it’s smart to inspect them whenever the wheels are off or the struts are out:

• Check the front strut bump-stops under the dust boots for splits, collapse, or oil contamination.
• Inspect the rear body-mounted stops for cracks, chunks missing, or binding marks.
• Replace in axle pairs to keep handling balanced.
• Choose quality OE-style polyurethane or microcellular foam parts, avoid mismatched “universal” sizes.
• If fitting new shocks/struts, do the bump-stops and boots at the same time.

Replacement is straightforward but safety-first: support the vehicle properly, and use a spring compressor for front struts. After any front strut work, book a wheel alignment. For cars carrying regular loads, towing, or running lowered springs, healthy bump-stops are even more important—they’re the last line of defence for suspension travel and help keep the Gran Move’s ride tidy and predictable.

• Do all 1997 Gran Moves have front and rear bump-stops?
  Yes. The front jounce bumpers live on the strut rods under the dust boots, and the rear bump-stops are mounted to the body above the axle beam. Both were specified by Daihatsu for the G300-series platform.
• How often should bump-stops be replaced on a Gran Move?
  There’s no strict interval, replace on condition. Inspect them whenever shocks/struts are serviced or every 40,000–60,000 km. If they’re cracked, mushy, oil-soaked, or missing pieces, swap them out.
• Can worn bump-stops cause clunks or tyre rub?
  They can. A degraded or missing bump-stop allows full metal-to-metal compression, causing a sharp thud, potential tyre-to-arch contact on big hits, and extra stress on mounts and dampers.
