Parts for your 2021 Suzuki Splash-Cv boots

2021 Suzuki Splash CV boots — what they do and when to service them

CV boots are absolutely relevant on a Suzuki Splash. Technical references including the Suzuki Electronic Parts Catalogue (Drive Shaft section) and the Splash/Ritz workshop service manual (Driveline/Axle — Front Drive Shaft) specify inboard and outboard constant–velocity joints protected by rubber boots on the front driveshafts. Independent databases such as Autodata and ALLDATA list the same arrangement for the Splash/Opel Agila B platform. Even though the Splash ceased production in many markets before 2021, a 2021-registered Splash or ongoing parts support still uses these CV boots as part of its front‑wheel‑drive layout.

The CV boots on a 2021 Suzuki Splash keep water and grit out of the front CV joints and hold the special moly grease in. That clean, packed grease lets the joints articulate smoothly as the wheels steer and the suspension moves. When the boots split, the grease flings out and road muck gets in, which quickly chews out the joint. Left too long, the tell-tale will be clicking on turns and a shudder under load — and that’s a whole driveshaft or joint replacement rather than a simple boot and grease job.

As part of routine servicing, it’s smart to check the Splash’s CV boots every 10,000–15,000 kilometres or at each service. Look for hairline cracks, splits at the convolutions, loose or rusty clamps, and grease mist on the inner rim or underbody. If there’s any damage, replace the boot straight away. A good workshop will clean the joint, inspect the bearings for pitting, repack with the correct CV molybdenum disulphide grease, fit new quality boots (OEM or OE‑spec TPE/neoprene), and crimp new stainless clamps with the proper tool. Fresh circlips and hub nuts are recommended, and torque specs from the Suzuki service manual should be followed.

Driving with a torn boot “for a bit” isn’t worth it. If caught early, a boot replacement is a tidy, cost‑effective fix that preserves the original driveshafts. If grit has already entered, the joint may need replacing, doing both boots on one axle in a single visit often saves time and repeat labour. After refitting, a quick check for play and a road test for noise on full lock will confirm all’s well. Keep those boots healthy, and the Splash’s front end stays tight, quiet and reliable.

• Signs to watch: grease flung around the wheel arch, clicking on turns, vibration on acceleration, or a visible split in the boot.
• Best practice: inspect at each service, replace at first damage, and always use the correct grease and new clamps.

Popular questions about 2021 Suzuki Splash CV boots

How often should CV boots be inspected on a Splash?
They’re best checked at every scheduled service or tyre rotation — roughly every 10,000–15,000 kilometres. A quick visual from under the front with a torch will usually spot early cracking or loose clamps before the joint is at risk.

Can a torn CV boot be temporarily taped?
Not reliably. Tape or glue won’t hold under rotation and heat, and it can trap grit inside the joint. If the boot has split, book a proper replacement as soon as possible to avoid turning a small repair into a full CV joint or shaft job.

What’s the difference between a bad boot and a bad CV joint?
A damaged boot is the split rubber cover, a bad joint is internal wear. Boots can often be replaced proactively. If you’re hearing clicking on full lock or feeling vibration on acceleration, the joint may already be worn and need replacement along with the boot.
