2006 Toyota Highlander (Kluger) CV Boots — What They Are and Why They Matter

CV boots are absolutely fitted to the 2006 Toyota Highlander (sold as Kluger in Australia and New Zealand). Technical sources confirming this include the Toyota Repair Manual (TIS) for the 2004–2007 Highlander/Kluger platform (MCU23/MCU28), which details inspection and service of front drive shaft boots, and the Toyota Electronic Parts Catalog (EPC), which lists inboard and outboard “Boot Kit, Front Drive Shaft” for this model. Aftermarket catalogues and workshop guides also specify front CV boots for all FWD variants and both front and rear CV boots for AWD variants, so the part is directly relevant to this vehicle.

On this Highlander/Kluger, CV boots are the flexible rubber covers over the constant velocity joints on the drive shafts. Their job is simple but critical: keep the special CV grease in and keep water, grit and dust out. When the boots stay intact, the joints remain quiet and smooth, and the vehicle steers and accelerates without shudders or clicks. If a boot tears, grease gets flung under the bonnet and road grime sneaks in, quickly wearing the joint.

As part of routine servicing, it’s smart practice for workshops to inspect all CV boots—front on FWD models, front and rear on AWD—looking for:

• Fine cracking, splits or perished rubber, especially on the outboard (wheel-side) boots
• Grease sling on the inner guard, strut, or underbody
• Loose or broken boot clamps
• Clicking on turns or vibration on take-off (often means joint damage has begun)

If caught early, a split boot can be replaced and the joint re-greased with the correct moly CV grease, restoring long service life. Quality OE-style boots and stainless clamps are worth it, and the axle nut should be tightened to the Toyota specification. If the joint has run dry or is noisy, replacing the complete shaft assembly is typically the more reliable fix.

Given Australia and New Zealand’s mix of coastal air, gravel roads and stop–start city driving, regular CV boot checks every service interval (or roughly every 10,000–15,000 km) help avoid bigger bills. AWD owners should ensure rear axle boots get the same attention as the fronts. Quick attention to a minor split can save the joint, keep the Highlander driving quietly, and maintain roadworthiness.

Do all 2006 Toyota Highlanders have CV boots?

Yes. All FWD models have front CV boots, AWD models have CV boots on both the front and rear drive shafts. Toyota’s repair manual and EPC list boot kits for these positions on the 2006 Highlander/Kluger.

Can a torn CV boot be replaced without changing the whole axle?

Often, yes. If the joint isn’t clicking or gritty and the tear is recent, a new boot and fresh CV grease usually sorts it. If contamination has been in there a while or noise is present, a complete shaft is the safer long-term option.

How often should CV boots be checked on a 2006 Highlander?

At every routine service. Many workshops include a quick visual underbody check—ideal in Aussie and Kiwi conditions where heat, salt air and rough roads can age rubber faster.
