Parts for your 2015 Ford Mondeo-Rack boots

2015 Ford Mondeo rack boots — what they do and when to replace them

Based on technical references, rack boots (also called steering rack bellows or gaiters) are absolutely used on the 2015 Ford Mondeo. The Ford Workshop Manual for the 2015 Mondeo/Fusion (Section 211-02: Steering System) details the rack-and-pinion assembly with protective bellows on each side of the steering gear. The Ford Electronic Parts Catalogue (ETIS/Microcat) lists a steering gear bellows/gaiter for 2014–2018 Mondeo models. Major parts catalogues and Motorcraft/aftermarket listings also supply direct-fit rack-and-pinion bellows kits for the 2015 Mondeo/Fusion platform. So, yes—this vehicle is fitted with rack boots, and they matter.

On a 2015 Mondeo, the rack boots protect the inner tie rod joints and the rack’s seals from grit, water, and road spray. They also keep the factory-applied grease where it belongs, so the inner joints move smoothly and quietly. Most 2015 Mondeos run electric power-assisted steering (EPAS), but the mechanical rack-and-pinion still relies on those rubber bellows to stay clean and healthy. Some racks use a small breather tube linking the boots to equalise air pressure—if that’s fitted, it mustn’t be kinked or left off during service.

During routine servicing, it’s smart to give the boots a quick check. Lightly flex the bellows and look for fine cracking, splits near the folds, perished rubber, loose or missing clamps, and any sign of contamination inside the boot. If a boot is damaged, replace it promptly—driving with a torn gaiter lets in abrasive muck that can chew out inner tie rods and rack seals.

• Inspect the boots at each service or roughly every 10–15,000 km.
• If replacing, use quality bellows and new clamps, avoid reusing corroded bands.
• Mark the tie-rod end position before removal to keep toe close, then get a wheel alignment.
• Check inner tie-rod play while the boot is off—replace if there’s looseness or notchiness.
• On EPAS models there’s no power steering fluid, so any oily residue may be rack grease or another leak nearby—investigate rather than ignoring it.

A tidy set of rack boots helps prevent premature wear, vague steering feel, and costly rack damage. For most owners, boot replacement isn’t frequent—just act quickly if there’s cracking or a split, and the Mondeo’s steering should stay sharp and quiet.

How often should rack boots be replaced on a 2015 Mondeo?

There’s no fixed interval. They should be inspected at every service, and replaced as soon as cracking, splitting, or loose clamps are spotted. In Aussie and Kiwi conditions—heat, UV, and road grime—rubber can age faster, so regular checks pay off.

Is it safe to drive with a torn rack boot?

Short trips might be unavoidable, but it’s not ideal. A torn gaiter lets grit and water reach the inner tie rod and rack seals, which can accelerate wear and lead to expensive repairs. Replace the boot promptly and book a wheel alignment afterwards.

Does the 2015 Mondeo have power steering fluid in the rack boots?

Most 2015 Mondeos use electric power-assisted steering, so there’s no hydraulic fluid. If you find oily residue, it may be rack grease or a nearby leak (for example from the engine or suspension). Don’t ignore it—get it checked so the boot and rack aren’t compromised.
