Parts for your 2018 Ford Transit-Coil springs

2018 Ford Transit coil springs — what they do and how to look after them

Technical references including the Ford Workshop Manual (WSM, Section 204-01 for 2015–2019 Transit) and the Ford Body and Equipment Mounting Manual (BEMM) confirm the 2018 Ford Transit runs MacPherson struts with coil springs on the front axle, while the rear axle uses leaf springs. So coil springs are absolutely relevant to this model, but they’re up front only.

On the front of a 2018 Transit, coil springs carry vehicle weight, set ride height and help control body movement when braking, cornering and rolling over uneven tarmac. Paired with the struts and top mounts, they keep the steering precise and the tyres in solid contact with the road. In day-to-day fleet use, they cop a fair workout from kerbs, corrugations and load transfers, especially on vans fitted with bull bars, racking or under-bonnet accessories that add front-end mass.

They’re not a scheduled replacement item, but they should be inspected at every service. Look for broken coil ends, sagging ride height side-to-side, rust pitting (common in salty or coastal areas), cracked or perished insulators, and shiny “polished” spots where coils touch. Any clunks over bumps, steering pull, or a nose-down stance with an empty van are clues the springs or related hardware need attention.

When replacement is due, it’s smart to:

• Match the spring rate to the van’s build code/VIN and front axle weight. Don’t guess — the correct spec matters for handling and braking.
• Replace in pairs to keep ride height and balance even.
• Renew associated bits while you’re there: strut bearings/top mounts, bump stops, dust boots and rubber isolators.
• Have a wheel alignment done after the job.
• Have compressed spring work handled by a pro — stored energy is no joke.

If the Transit regularly carries heavy front accessories or runs rough regional roads, consider an uprated front spring set approved for the axle rating and local compliance (ADR/WoF). Avoid spacer fixes that upset geometry. After installation, torque fasteners at normal ride height (vehicle on its wheels) so bushes settle correctly and don’t tear out prematurely. With basic checks each service and quality parts when needed, the front coils will keep the big Ford riding level and steering sweet for many kilometres.

FAQs

Does a 2018 Ford Transit have rear coil springs?
No. The rear of the 2018 Transit uses leaf springs to handle cargo loads, only the front axle uses coil springs. Some aftermarket conversions exist, but from the factory it’s leaf-sprung at the back.

How often should the front coil springs be replaced?
There’s no fixed interval. Inspect them at each service and replace if a coil is broken, the van sits low on one side, or there’s corrosion, noise or poor handling. Many sets last well beyond 150,000 km, but heavy loads and harsh roads can shorten their life.

Are stock front coils OK for towing or heavy loads?
Yes, because the rear carries most of the load. The front coils still manage braking and steering forces, so ensure they match the build code and any added front accessories. If you’ve fitted a bull bar or winch, talk to a suspension specialist about ADR/WoF-compliant uprated front springs.
