2016 Toyota RAV4 rack-boots: what they do and how to look after them

Technical confirmation: The 2016 Toyota RAV4 (ZSA42R/ASA44R/ALA49R series) uses a rack-and-pinion steering system with electric power assist, and it is fitted with steering rack boots (also called bellows or gaiters). This is documented in Toyota’s Repair Manual (TIS) under Steering—Steering Linkage and Gear, and shown in the Toyota Electronic Parts Catalogue where “steering gear boots” and boot clamps are listed for both sides of the rack. So, rack-boots are absolutely relevant on this model.

On this RAV4, the rack-boots sit on either end of the steering rack, sealing the inner tie-rod joints and the rack ends from water, dust, and road grit. They keep the factory grease where it belongs and stop contaminants from chewing out the rack end or inner tie-rod sockets. Even though the vehicle uses electric power steering rather than a hydraulic setup, the boots still do the heavy lifting in protecting the moving bits from wear.

For day-to-day ownership, it’s wise to have the rack-boots inspected at every scheduled service (typically every 12 months or 15,000 km in AU/NZ service programs). A quick look for splits, perishing, loose clamps, or grease sling on the inside of the front wheels can save a bigger bill later. If a boot is cracked or torn, moisture and grit can get in fast, accelerating play in the inner tie rod and, in the worst case, damaging the rack bar or seals.

Common signs a rack-boot needs attention include:

• Visible splits, tears, or heavy cracking on the bellows
• Grease flung around the inner wheel arch or subframe
• Clicking, knocking, or vague steering feel
• Uneven front tyre wear after rain or dirt-road use

Replacement is straightforward for a trained tech: the outer tie-rod end is removed, old clamps cut, the boot slid off, and the inner joint inspected. Fresh grease is applied to the joint as specified by Toyota, a new genuine or quality aftermarket boot is fitted, and new clamps are crimped to spec. Care is taken not to twist the boot and, on racks with a breather, to keep any vent path clear so the bellows can compress and expand without pressure build-up. Because the outer tie rod is disturbed, a wheel alignment is recommended straight after.

If the vehicle is used on unsealed roads or at the beach, ask the workshop to give the boots a closer look between regular services. Keeping them intact is cheap insurance for the steering gear and your tyres.

Popular questions about 2016 Toyota RAV4 rack-boots

Do all 2016 RAV4s have rack-boots?
Yes. Per Toyota’s service information and parts catalogues for the ZSA42R/ASA44R/ALA49R platform, every 2016 RAV4 uses rack-and-pinion steering with a protective boot on each side. Electric power assist doesn’t replace the boots, it just changes how assist is provided.

How often should the rack-boots be replaced?
There’s no fixed kilometre-based replacement interval. They’re inspected at each service and replaced when damaged, perished, or loose. In Australia and New Zealand, that typically means a check every 12 months/15,000 km, and more often if the car sees gravel roads, mud, or beach work.

Is it safe to drive with a torn rack-boot?
It’s not a great idea. A torn boot lets water and grit into the inner tie-rod joint and onto the rack, which can lead to play, noise, and premature wear. Driving a short distance to a workshop is usually fine, but prompt replacement and a follow-up alignment are strongly recommended.
