Parts for your 2012 Mazda Bt-50-Rack boots

2012 Mazda BT-50 Rack Boots (Steering Rack Gaiters)

Based on technical literature for this model, rack boots are fitted to the 2012 Mazda BT-50. The Mazda BT-50 Workshop Manual for the 2011–2015 generation (steering section) specifies a rack-and-pinion steering gear that uses rubber bellows (rack boots/gaiters) on both ends of the rack. The Mazda Electronic Parts Catalogue also lists the boots and clamps for the steering rack, and the platform twin—Ford Ranger PX—shows the same arrangement in its workshop documentation.

On the 2012 BT-50, rack boots do a deceptively big job. These flexible bellows seal the ends of the steering rack and the inner tie rods, keeping water, mud, dust and grit out of the moving bits while letting the rack travel freely lock-to-lock. For a ute that often sees corrugated roads, job sites and the odd water crossing around Australia and New Zealand, healthy rack boots protect the inner tie rod joints and the rack itself from premature wear and corrosion. They also help keep any lubricants where they belong and stop road grime from turning into grinding paste.

As part of regular servicing, it’s smart to give the rack boots a proper look. Check for splits, perishing, missing or loose clamps, and any sign of oil or fluid inside the boot. A torn boot can quickly allow contamination into the inner tie rod and along the rack bar, which then shows up as vague steering, notchy feel, or uneven tyre wear. If there’s power steering fluid pooling in a boot, that usually points to an internal rack seal leak—boots won’t fix that, the rack needs repair or replacement.

When replacing rack boots on a BT-50, use quality OE-style boots and proper stainless clamps rather than cable ties. Remove the outer tie rod end to slide the boot off, and count or mark threads to keep toe close before heading for a wheel alignment. Don’t over-pack the boot with grease, follow the workshop manual—many inner joints are pre-lubed and sealed. After fitting, cycle the steering from lock to lock before fully tightening clamps so the boot sits naturally without twisting.

Given the BT-50’s working life, it’s worth inspecting the boots at every service or after heavy off-road or floodwater use. It’s a quick, low-cost check that can save a steering rack down the track.

• Look for cracks, splits, or loose/missing clamps
• Check for fluid inside the boot (possible rack seal leak)
• Replace boots promptly and book an alignment afterwards

Does a 2012 Mazda BT-50 have rack boots?

Yes. The 2012 BT-50 uses a rack-and-pinion steering gear with rubber bellows (rack boots) on each end, as shown in Mazda’s workshop manual and parts catalogue. They’re a standard wear item that protects the inner tie rods and steering rack from dirt and water.

How can someone spot a failing rack boot on a BT-50?

Common signs include visible splits or perished rubber, grease flung around the inner guard, or a boot that’s slipped its clamp. If there’s oily fluid inside the boot, that often indicates a leaking rack seal rather than just a bad boot. Left alone, contamination can wear out inner tie rods and the rack.

Is it safe to drive with a torn rack boot?

It will drive, but it’s not a good idea for long. A torn boot lets grit and water into the steering, accelerating wear and potentially affecting steering feel and tyre wear. Replace the boot as soon as practical and get a wheel alignment to keep the BT-50 tracking straight.
