Parts for your 2010 Toyota Hilux-Rack boots

2010 Toyota Hilux rack boots: what they do and when to replace them

Based on technical sources, rack boots are absolutely fitted to the 2010 Toyota Hilux. Toyota’s Electronic Parts Catalogue lists “Boot, Steering Rack” for the N70-series Hilux (e.g., KUN26R/GGN25R) with part numbers such as 45535-0K010, and the Toyota Repair Manual steering section shows a rack-and-pinion gear with bellows-style boots on both ends. That means the 2010 Hilux uses rack boots, and they’re a routine service item worth keeping an eye on.

On this ute, the rack boots (also called bellows or gaiters) protect the steering rack and inner tie rod joints from mud, water, dust, and road grime. They also help keep the correct amount of lubrication inside the inner joint area and allow the steering to move through its range without exposing the rack shaft. When a boot splits, grit can chew out the inner tie rod and the rack seals, leading to play, shudder, or power-steering fluid leaks — and a likely RWC/WOF fail.

For a 2010 Hilux, it’s smart to inspect the rack boots at each service interval (about every 10,000–15,000 km or six months, whichever comes first), especially if it sees corrugations, beach work, or farm tracks. Look for cracks, oil misting, loose clamps, or boots that feel hard and brittle. If a boot is torn, replace it straight away to prevent water ingress and expensive steering gear damage.

When replacing, use quality boots that match the OE dimensions and fit proper clamps (not cable ties). The boot shouldn’t be twisted on the rack, and the ends must be seated cleanly on the grooves. Only a light smear of grease is usually needed on the inner joint area — don’t pack the boot full, as it can pop clamps or affect steering feel. If the inner tie rod is disturbed during the job, a wheel alignment is recommended, for a boot-only swap where the outer tie rod position isn’t changed, alignment may still be worth checking if there’s any doubt.

• Common signs a boot needs attention:
  • Visible splits or perishing
  • Oil residue on or inside the boot
  • Clicking or free play around centre
• Service tip: After deep water crossings or beach runs, rinse the underbody and re-check the boots next wash-down.

Popular questions

Do 2010 Hilux models have rack boots on both sides?

Yes. The 2010 Hilux rack-and-pinion assembly uses a bellows boot on each end of the rack to seal the rack shaft and inner tie rod area from dirt and moisture. If one is damaged, it’s wise to inspect and often replace them as a pair.

Do you need a wheel alignment after replacing rack boots?

If the outer tie rod length isn’t altered, an alignment may not strictly be necessary. However, in real-world servicing it’s common to check or perform an alignment afterward, especially if the tie rod or lock nuts were loosened or there’s any change in steering feel or tyre wear.

How long do rack boots last on a Hilux in Aussie/Kiwi conditions?

Lifespan varies with use. Many last years, but frequent off-road, mud, sand, or heat exposure can crack or split them sooner. A quick look at every service and prompt replacement when perishing shows up will protect the rack and save money down the track.
