2002 Daihatsu Gran Move Rack Boots

Based on the Daihatsu Gran Move/Pyzar G30-series Factory Service Manual (Chassis & Steering section) and the Daihatsu Electronic Parts Catalogue for models G303/G311, the 2002 Daihatsu Gran Move uses a rack-and-pinion steering gear with bellows-style dust boots (often called rack boots or rack gaiters). Aftermarket parts catalogues for this model range also list replacement rack boots, confirming the component is fitted from factory.

On the 2002 Gran Move, the rack boots are the flexible rubber bellows that seal each end of the steering rack. Their job is to keep grit, water, and road spray out of the rack-and-pinion and inner tie rod joints, and to contain the light grease or, on power-steer models, to manage pressure equalisation at the ends of the rack. When the boots split or harden, moisture and contaminants sneak in, quickly wearing the rack bar and inner joints, and power steering fluid can seep out under the boot on PS racks.

For routine servicing, it’s smart to inspect the rack boots whenever the front end is up—think every 10,000–15,000 km, or during a tyre rotation. If there’s any cracking, oiliness, or loose clamps, replacement is the safe bet. A torn boot is often a fail at a WOF (NZ) or roadworthy/reg inspection (AU), and leaving it can turn a cheap boot job into a costly steering rack rebuild.

• Replace boots in pairs where possible to keep wear and steering feel even.
• Use proper stainless ear clamps or OEM-style clamps rather than cable ties for a secure seal.
• Set the rack at centre and ensure the boot isn’t twisted before clamping, check that breather paths (if fitted) aren’t blocked.
• A four-wheel alignment is recommended after boot replacement, especially if tie rods were disturbed.
• A light smear of silicone grease on the boot lips can help seating, avoid petroleum-based products that attack rubber.

Common signs the Gran Move’s rack boots need attention include perished rubber, visible splits in the bellows, dampness of power steering fluid around the boot, a gritty steering feel, or uneven front tyre wear from inner joint contamination. Age, ozone, and road debris are the usual culprits—these little bellows live a tough life just behind the front wheels. Keeping them fresh is cheap insurance for the steering gear and helps the car track straight and steer smoothly on Aussie and Kiwi roads.

Popular questions about 2002 Daihatsu Gran Move rack boots

Does the 2002 Daihatsu Gran Move have rack boots?
Yes. Technical references, including the Daihatsu Gran Move/Pyzar factory manual and the Daihatsu EPC for G303/G311, show a rack‑and‑pinion steering gear with bellows boots on both ends. Most aftermarket catalogues also list direct-fit rack boots for this model year.

How often should rack boots be replaced?
There’s no strict interval, they’re replaced on condition. Inspect at every service or 10,000–15,000 km. If the rubber is cracked, split, oily, or the clamps are loose, replace them promptly to protect the steering rack and inner tie rods.

Will split rack boots fail a WOF or rego check?
Often, yes. In NZ a torn or insecure steering boot is commonly a WOF fail, and in AU it can knock back a roadworthy/reg inspection. Replacing damaged boots before inspection helps avoid defects and prevents bigger steering repairs down the track.
