Parts for your 2015 Toyota Fortuner-Rack boots

2015 Toyota Fortuner rack boots — what they do and when to replace them

Yes, rack boots are relevant to the 2015 Toyota Fortuner. Toyota’s technical literature for both late first‑gen Fortuner (AN50/AN60) and the 2015‑on second‑gen (AN150/AN160) specifies a rack‑and‑pinion steering gear, and the Toyota Repair Manual and Electronic Parts Catalogue list “Boot, Steering Rack” and the associated clamps as service parts on each side of the steering gear. That means this model does in fact use rack boots (also called rack bellows).

On a Fortuner that sees a mix of city runs and off‑road tracks, the rack boots do a quiet but crucial job. They’re the flexible bellows that seal each end of the steering rack, keeping grit, mud, water and dust away from the inner tie‑rods and rack seals. They also help the rack breathe as it moves lock‑to‑lock, keeping grease where it should be. If a boot splits, contaminants get in and the inner tie‑rod and rack seals cop a hiding. On hydraulic racks that can lead to power‑steering fluid leaks, on electric‑assist or low‑assist setups it can still mean corrosion and premature wear.

As part of routine servicing in Australia and New Zealand, it’s smart to have the rack boots inspected every service or 10,000–15,000 kilometres, and especially after beach runs, water crossings or muddy trips. Signs they’re due include cracks, perishing, oily residue around the boot, or visible tears. If there’s moisture or grit inside a boot, don’t ignore it—damage escalates quickly once contamination starts.

• Inspect on a hoist with the steering turned both ways to reveal hidden splits.
• Replace in pairs if one has failed, using quality boots designed for the Fortuner’s rack travel.
• Always renew the clamps, avoid cable ties as they loosen with heat cycles.
• If a balance/vent tube is fitted between boots, refit or replace it so the rack can breathe properly.
• After boot or inner tie‑rod work, have the wheel alignment checked and set.
• Post‑off‑road, rinse the underbody gently—no aggressive pressure directly at the boots.

A tidy set of boots keeps the steering precise, the rack seals happy, and helps avoid a bigger bill down the track. For parts selection, use the VIN to match the correct boot and clamp set shown in the Toyota EPC for your exact build month.

How can someone tell if a Fortuner’s rack boots are torn?

Look for grease or fluid misting around the boot ends, visible splits in the bellows, or dirt inside the boot. Turning the steering from lock to lock while the vehicle is raised often reveals cracks that sit in the folds. Any contamination inside the boot is a red flag for inner tie‑rod and rack seal wear.

Is it safe to keep driving with a split rack boot?

Short trips to a workshop are usually fine, but continuing to drive invites water and grit into the rack. That can quickly turn a simple boot job into inner tie‑rod or steering rack repairs. It’s best to sort it promptly.

Do 2015 Fortuner rack boots differ between models?

They can. Steering gear variants and production dates may use different boot and clamp part numbers. Always match by VIN in the Toyota EPC to ensure the boot’s length, inner diameters and travel are correct.
