Parts for your 2002 Daihatsu Gran move-Bump stops

2002 Daihatsu Gran Move bump-stops

Bump-stops are absolutely relevant on the 2002 Daihatsu Gran Move. Technical references confirm they’re fitted from factory: the Daihatsu Pyzar/Gran Move (G3) workshop manual shows a “bump rubber” integrated on the front MacPherson strut, and a separate “bump stopper” on the body above the rear torsion-beam axle. The Daihatsu Electronic Parts Catalogue (G3/Pyzar/Gran Move, 1996–2002) also lists these as individual service parts for both front and rear. So, if the Gran Move’s suspension bottoms out, those jounce bumpers are doing the hard yards to protect the struts, shocks, and body mounts.

On this model, the front bump-stop lives inside the strut assembly beneath the dust boot, cushioning the final part of travel on big hits. At the rear, the beam contacts the body-mounted stopper on heavy loads or deep compressions. Their job is to control the last bit of suspension movement, preventing metal-to-metal contact, reducing harshness, and keeping the alignment gear and dampers safe when the springs are fully compressed.

Because they’re usually polyurethane or microcellular foam, they age, crack, or crumble—especially on vehicles that carry a bit of load, see rough roads, or have tired shocks. During servicing, it’s smart to check them whenever tyres, brakes, or suspension are off, and definitely any time the struts or shocks are replaced.

• Typical signs they need attention:
  • Frequent “thud” on big bumps, or the car bottoms out
  • Perished, split, or missing bump-stops or dust boots
  • Uneven tyre wear or a vague rear-end when loaded
• Good practice:
  • Inspect every 20,000–30,000 km or annually with suspension checks
  • Replace bump-stops and dust boots whenever fitting new struts/shocks
  • Always replace in axle pairs and book a wheel alignment after front strut work

Fitting is straightforward for a pro: fronts require strut removal and spring compression, rears are usually accessible on the body tower. Use new hardware where specified and follow the workshop manual torque specs for the strut top nut and knuckle bolts. If a Gran Move is carrying more weight than usual (camping gear, tools), consider checking them a bit more often—the bump-stops are the last line of defence before things get expensive.

Popular questions

Does a 2002 Daihatsu Gran Move actually have bump-stops?
Yes. The factory workshop manual for the G3 Pyzar/Gran Move identifies a front strut “bump rubber” and a rear body-mounted “bump stopper”, and the Daihatsu EPC lists both as service parts.

How often should bump-stops be replaced on a Gran Move?
There’s no fixed interval. Inspect them at each suspension service (roughly every 20,000–30,000 km) and replace whenever they’re cracked, softened, missing, or when you’re fitting new shocks/struts.

Is it safe to drive without bump-stops?
Not really. Without them the suspension can bottom out hard, risking damage to shocks, mounts, and even the body. It also feels rough and unsettled over big hits.
