Parts for your 2021 Suzuki Splash-Rack boots

2021 Suzuki Splash rack-boots: relevance and service advice

Based on technical sources, rack-boots are absolutely relevant to the Suzuki Splash platform. The Suzuki Splash Service/Workshop Manuals (Steering section), the Maruti Ritz (Indian-market Splash) Workshop Manual, and Suzuki’s Global Service Way EPC all show a rack-and-pinion steering gear with protective bellows-style rack-boots and boot clamps. The sister model Opel/Vauxhall Agila B technical diagrams also depict the same arrangement. While the Splash wasn’t produced as a new model year in 2021 in most markets, vehicles registered or still on the road in 2021 use this same steering design—so rack-boots apply.

On the Splash, rack-boots (also called steering rack gaiters) do a simple but vital job: they seal the ends of the rack-and-pinion so grease stays put and grit, water, and road grime stay out. Because most Splashes run column-assist electric power steering, there’s no hydraulic fluid at the rack—but the mechanical rack still needs clean lubrication and protection. When a boot splits, the inner tie-rod and rack end cop the elements, which can lead to notchy steering, premature wear, and even warrant or roadworthy issues across NZ and Australia.

Good servicing practice is to inspect both rack-boots at every service or at least every 10,000–15,000 km. Look for perished rubber, cracks at the concertinas, loose or rusty clamps, and telltale grease flung around the subframe. Any dampness mixed with road dirt at the boot ends is a red flag. They’re not a ‘replace by time’ item, but on city runabouts like the Splash, heat, UV, and lock-to-lock parking manoeuvres mean boots can age out in 5–10 years.

Replacement is straightforward for a competent tech, but it’s more than just slipping on new rubber. Expect to remove the outer tie-rod end, mark or count threads to keep toe close, slide off the old boot and clamps, clean the rack end, apply the correct lubricant, then fit a quality boot (TPE or OE-spec rubber) with new clamps. Avoid twisting the boot, verify free steering movement, and always finish with a proper wheel alignment—any time a tie-rod end is disturbed, toe can shift. If corrosion has seized locknuts, penetrating fluid and heat may be needed, forcing things risks damaging the inner joint or rack.

Owners who keep the rack-boots intact enjoy quieter, lighter steering, longer inner tie-rod life, and fewer surprise costs. It’s a small part that saves the big-ticket steering rack from gritty, expensive damage.

• Signs it’s time: cracked bellows, grease sling, clicking or notchy steering, WOF/roadworthy fail notes.
• Pro tips: replace in pairs if they’re the same age, use new clamps, book an alignment straight after.

Popular questions

Does a 2021 Suzuki Splash actually have rack-boots?
Yes. Although the Splash wasn’t newly produced in 2021 in most markets, the platform uses a rack-and-pinion steering gear with bellows-style rack-boots. Any Splash on the road in 2021 still relies on those boots for sealing and protection.

How often should rack-boots be replaced on a Splash?
There’s no fixed interval. Check them every service, replace at the first sign of cracking, splits, loose clamps, or contamination. Many last 5–10 years, but heat, UV, and tight parking can age them faster.

Do they need a wheel alignment after replacing rack-boots?
Yes. Because the outer tie-rod end is typically removed to swap the boot, toe settings can change. A wheel alignment after the job protects tyre wear and steering feel.
