2007 Toyota Highlander/Kluger rack boots: what they do and when to replace them

Yes, rack boots are absolutely used on the 2007 Toyota Highlander (known as Kluger in Australia and New Zealand). Technical references including the Toyota Repair Manual (Steering—Rack and Pinion section, Toyota Technical Information System), the Toyota Electronic Parts Catalog, and general service guides such as the Haynes Toyota Highlander 2001–2007 manual all show rubber bellows (rack boots) fitted to each end of the steering rack to protect the inner tie rods and rack shaft.

On this model, the rack boots are flexible bellows that keep grit, water, and road grime away from the inner tie-rod joints and rack seals. They also help retain grease where it needs to be and let the air inside the boot expand and contract as the steering moves from lock to lock. When they’re intact, the steering stays smooth and the rack components last a lot longer.

For owners and technicians looking after a 2007 Highlander/Kluger, regular visual checks of the rack boots should be part of every service. Any cracks, splits, perishing, or grease weeping around the clamps is a red flag. If a boot tears, contaminants can chew out the inner tie-rod joint and allow moisture to reach the rack seals, which can shorten the life of the steering gear. Catching a failing boot early is far cheaper than replacing a rack.

Replacement is straightforward for a competent tech. The outer tie-rod end is removed, the old boot and clamps are taken off, the inner joint is cleaned and re-greased as required, then a new boot is fitted with proper ear or spring clamps. Counting the threads or marking the tie-rod helps keep toe close, but a wheel alignment is still recommended straight after.

• Service tip: inspect boots at each oil change or at least every 15,000 km, and after off‑road, flood, or beach driving.
• Choose quality OEM or equivalent boots with proper clamps—skip zip ties, as they don’t seal as well.
• Replace in pairs if one side has failed, the other is usually not far behind.
• After fitting, turn the steering lock-to-lock to ensure the boot doesn’t twist or foul anything.

Look after the boots and the Highlander/Kluger’s hydraulic rack-and-pinion will generally go the distance without drama.

Popular questions about 2007 Toyota Highlander/Kluger rack boots

How can someone tell if the rack boots need replacing?

They should look for visible cracks, splits, or grease on the outside of the boot or around the clamps. A clicking inner tie rod when turning or uneven tyre wear can hint that contamination has already started causing wear. Any sign of perishing means it’s time to replace before the rack or inner joint cops damage.

Is it okay to keep driving with a torn rack boot?

It’ll still steer, but it’s not a good idea. A torn boot lets in water and grit, which can quickly wear the inner tie rod and the rack seals. That can turn a cheap boot job into a pricey rack replacement, and it may also fail a WOF/roadworthy. Best to sort it promptly.

Do they need a wheel alignment after replacing rack boots?

Yes. Even if the threads are counted and marked, removing the outer tie-rod end can nudge the toe setting. A post-repair alignment ensures straight tracking, even tyre wear, and proper on-centre feel.
