Parts for your 2007 Toyota Highlander-Steering bushes

2007 Toyota Highlander steering bushes — what they do and when to replace

Yes, the 2007 Toyota Highlander (first‑gen XU20, also known as Kluger in AU/NZ) does use steering bushes. Toyota’s service literature and parts catalogue list rubber insulators/cushions that secure the steering rack to the front subframe. See Toyota’s Repair Manual (TIS) for 2001–2007 Highlander/Kluger, Steering Gear section, and the Toyota Electronic Parts Catalogue illustration for “Steering Gear & Link,” which both show the rack mounting bushes and brackets. Those bushes isolate vibration, keep the rack properly located, and help deliver a consistent steering feel.

The purpose of the steering (rack) bushes is to mount the rack-and-pinion securely while soaking up noise and harshness from the road. Over time the rubber can harden, crack, or swell from power steering fluid exposure, which allows the rack to shift slightly under load. That movement shows up as clunks over bumps, a vague on‑centre feel, or the steering wheel twitching under acceleration and braking. Keeping the bushes in good nick protects tyres, helps the car track straight, and preserves that easy Highlander/Kluger steering character.

• Common signs they’re tired: a dull knock on turn‑in or over potholes, vague steering, tramlining, or visible perishing in the bush rubber.
• If there’s a power steering fluid leak, expect the bushes to deteriorate faster.
• Excess play at the rack mounts when a helper rocks the steering wheel is a giveaway.

Replacement is straightforward workshop work: support the rack, remove the mounting brackets, swap the bushes, refit and torque to spec, then road‑test. It’s smart to check wheel alignment afterwards, as any subtle shift in rack position can nudge toe settings. For most daily driving, genuine‑style rubber bushes maintain the intended comfort and NVH. Polyurethane options can sharpen response but may add a touch more road feel and noise—great for enthusiasts, less ideal if quiet comfort is the goal.

As part of routine servicing at 100,000–150,000 km, a visual inspection of the steering bushes is worth adding to the checklist, especially if the vehicle tows or sees rough roads. While there, also inspect inner/outer tie rods, rack boots, sway bar links, and front control arm bushes, worn parts often show up together. Fix any power steering leaks before or during bush replacement so the new bushes last properly. Done right, fresh bushes bring back that tidy, confident steering the 2007 Highlander/Kluger is known for.

• Are steering bushes the same as control arm bushes on a 2007 Highlander?
  Not quite. Control arm bushes live in the suspension arms, while steering bushes mount the rack to the subframe. Both affect steering feel, but if the knock is felt mostly through the wheel on turn‑in, it’s more likely rack bushes or tie rods, if it’s over bumps and under braking, control arm bushes may be the culprit.
• Do steering bushes need wheel alignment after replacement?
  Alignment isn’t always mandatory, but it’s recommended. Even small changes at the rack mounts can subtly affect toe. A quick alignment check after bush replacement avoids uneven tyre wear and keeps the Highlander tracking arrow straight.
• Rubber or polyurethane bushes—what’s better for a daily driver?
  For most owners, quality rubber matches Toyota’s original balance of comfort and control. Polyurethane tightens response and can last longer, but it may transmit a bit more road feel. If the Highlander mainly does family duty and commuting, rubber is usually the sweet spot.
