2013 Toyota bB Rack-Boots — What They Do and When to Replace

Yes, the 2013 Toyota bB uses rack-boots. Toyota’s Repair Manual for the QNC2# bB (Steering section) describes inspection and replacement of the steering rack bellows, and the Toyota Electronic Parts Catalogue (EPC) lists the “Boot, Steering Gear” for both sides of the rack. That makes rack-boots relevant and essential on this model.

On a 2013 bB, the steering is rack-and-pinion with electric assist, and the rack-boots (also called steering rack bellows or gaiters) are the flexible rubber sleeves at each end of the rack housing. Their job is simple but critical: they keep dust, water, and road grit out of the rack and inner tie-rod joints, while holding the correct lubricant around the rack ends. If a boot splits, muck gets in, grease gets washed out, and the inner tie rod and rack can wear fast, leading to play in the steering and a potential WOF/roadworthy fail.

As part of routine servicing in Australia and New Zealand, it’s smart to visually check the rack-boots every service or 10,000–15,000 km. Look for cracks, tears, missing or loose clamps, or perished rubber. A light coating of road grime is normal, but any sign of exposed metal at the inner joint, or a boot that’s gone hard and brittle, means it’s time for replacement.

When replacing, most techs do both sides together. The outer tie-rod end is separated from the knuckle, the boot and clamps are removed, fresh specified grease is applied at the inner joint (as outlined in the Toyota Repair Manual), and new boots and clamps are fitted, making sure the bellows aren’t twisted at full lock. It’s good practice to check inner tie-rod play while you’re there. After refitting, a wheel alignment is recommended, because even careful reassembly can nudge toe settings.

• Common symptoms of a bad rack-boot on a bB:
  • Visible split or missing clamp
  • Clicking/knocking over bumps from inner tie-rod wear
  • Inconsistent steering feel after rain or puddles
• Pro tips:
  • Use quality boots and proper crimp clamps, not cable ties
  • Avoid solvents on the rubber—use mild cleaner only
  • Inspect after rough-road or flood-water driving

Look after the rack-boots on a 2013 Toyota bB and the steering stays tight, quiet, and compliant for years.

Does the 2013 Toyota bB actually have rack-boots?

It does. The model runs a rack-and-pinion steering setup with electric assist, and Toyota’s Repair Manual and EPC both show the “Boot, Steering Gear” on each side. They’re standard equipment and a key protective part.

How often should rack-boots be inspected or replaced on a bB?

Have them checked at every service or roughly every 10,000–15,000 km. Replace them as soon as cracks, splits, or loose clamps are found. They’re inexpensive compared to the cost of a worn rack or inner tie rods.

Is it safe to drive with a torn rack-boot?

It’s not recommended. A torn boot lets water and grit attack the inner tie rod and rack, which can quickly create steering play. It may also lead to a WOF/roadworthy fail. Sort it promptly and get an alignment afterwards.
