Parts for your 2013 Mazda Bt-50-Rack boots

2013 Mazda BT-50 Rack Boots

Rack boots are absolutely relevant to the 2013 Mazda BT-50. The BT-50 (UP series, 2011–2015) uses a rack-and-pinion steering gear, and each end of the rack is protected by a concertina-style boot. This is backed by the Mazda BT-50 (UP/UR) Workshop Manual for the Steering System, the Ford Ranger PX (2011–2015) Workshop Manual used on the same platform, and Mazda’s Electronic Parts Catalogue, all of which show left and right steering gear boots specified for this model.

On this ute, the rack boots (also called steering rack bellows or gaiters) keep dust, water and mud out of the rack, inner tie rod and shaft. They also help retain the grease sitting on the inner joint, which keeps steering movement smooth and reduces wear. A key point: the boots aren’t meant to hold power-steering fluid. If fluid is found inside a boot, that’s a tip-off the rack’s internal seals are leaking and the rack may need repair or replacement.

For owners who tow, tour or head off-road, the boots cop a fair bit of grime and flexing. It’s worth giving them a look at every service, or after deep water crossings. If a boot is split, perished or loose on its clamp, it should be replaced straight away to avoid grit chewing out the inner tie rod and the rack itself.

• Typical signs of trouble: visible cracks or tears, grease contamination with grit, steering feel getting notchy, or uneven tyre wear from inner joint wear.
• Best practice: replace boots in pairs, fit correct clamps (not cable ties), and check inner tie rod play while you’re there.
• If the outer tie-rod end is removed to swap a boot, a wheel alignment is recommended.

Replacement is straightforward for a trained tech: lift and secure the front, mark and remove the outer tie-rod end, slide off the old boot, clean and lightly regrease the inner joint, then fit the new boot with proper clamps at both ends. On high-kilometre or hard-work BT-50s, inspecting the inner tie rod and rack ends during boot replacement can save a second job later. Using quality OEM-equivalent boots helps them last longer in Aussie and Kiwi conditions, where UV, heat and mud can be relentless.

Popular questions about 2013 Mazda BT-50 rack boots

Do torn rack boots damage the steering rack?
Yes. Once a boot splits, water and grit can get onto the rack and inner tie rod, accelerating wear. If left too long, it can lead to play in the steering and, in bad cases, rack replacement. If power-steering fluid is found in the boot, that points to internal rack seal failure rather than just a boot issue.

How often should rack boots be replaced?
There’s no fixed interval. They’re replaced on condition. On a 2013 BT-50 used on-road, they can last many years, vehicles used off-road or in harsh sun may see boots perish sooner. Inspect them at each service and after water crossings, and replace at the first sign of cracking or tearing.

Is a wheel alignment needed after changing a rack boot?
If the outer tie-rod end was removed or its locknut disturbed, a wheel alignment is a good idea to protect tyres and steering feel. If the boot was changed without altering toe settings, alignment may not shift, but most workshops will still check it.
