Parts for your 2018 Ford Fiesta-Cv boots

2018 Ford Fiesta CV boots — what they do and when to service them

Based on technical sources, CV boots are absolutely used on the 2018 Ford Fiesta. The Ford Workshop Manual (Section 205-04: Front Drive Halfshafts) specifies inner tripod and outer Rzeppa CV joints protected by thermoplastic boots and crimped clamps. The Ford parts catalogue for the 2018 Fiesta lists front driveshaft assemblies with separate inner and outer boot kits (including grease and clamps). Independent service manuals for the Fiesta (2008–2019 coverage) also detail routine inspection and replacement of CV boots. So, yes — the 2018 Fiesta is fitted with CV boots.

On a front‑wheel‑drive Fiesta, the CV boots keep special moly grease inside the constant‑velocity joints and keep water, grit, and road grime out. The outer boot protects the joint that steers and copes with big angles, the inner boot covers the plunge joint that handles suspension movement. When the boots stay intact, the joints run quietly and last for ages.

Good servicing is simple, and very worth it. At each service or about every 10–15,000 km, a quick look behind the front wheels for torn rubber or a sling of dark grease goes a long way. If there’s grease splattered around the inner guard or wheel, or a visible split, the boot needs replacing before the joint dries out or rusts. A clicking noise on low‑speed turns is a classic sign the outer joint has already worn, at that point a full joint or driveshaft replacement is usually smarter than just a boot.

• Use a quality boot kit matched to the Fiesta’s side and joint type (inner vs outer).
• Pack the joint with the correct moly CV grease supplied, don’t mix greases.
• Fit new stainless clamps and crimp with the proper ear‑clamp tool so they don’t weep.
• Seat the boot ribs in their grooves and avoid twisting the bellows.
• Refit hardware with new fasteners where specified and torque to the Ford spec from the workshop manual.

Workshops in Australia and New Zealand will also note roadworthy/WOF concerns: any split or leaking CV boot is typically a fail item. Catching a small crack early saves a lot — a boot kit and fresh grease is far cheaper than a new shaft. After any driveshaft work, a quick test drive to check for noise or vibration is a must, if the lower arm was separated, an alignment check is a good idea.

Popular questions

How often should CV boots be inspected on a 2018 Ford Fiesta?
They’re best checked at every regular service, or roughly every 10–15,000 kilometres. If the car sees a lot of gravel, flooding, or coastal roads, have a peek more often. A fast glance for grease spray or small cracks can prevent costly CV joint damage.

Can a split CV boot be patched or can a “split boot” be used?
Tape or glue patches won’t hold up. Universal split boots can get someone out of trouble short‑term, but the proper fix is a model‑specific boot kit with the right grease and clamps. That restores sealing and longevity.

Are the inner and outer CV boots the same on a Fiesta?
No. The inner boot suits the tripod joint and the outer boot suits the Rzeppa joint. They’re different shapes and clamp sizes. Always order by VIN or side to get the correct fitment.
