Trailer Parts in Practice: Jockey Wheels, Couplings and Spare Wheels

New lockable trailer coupling head and replacement jockey wheel assembly fitted at Sleaford Trailers

A stiff trailer jockey wheel, a worn coupling head or a missing spare wheel can all lead to a parts enquiry. The first step is identifying a suitable replacement for the trailer, rather than choosing an item simply because it looks similar.

At Sleaford Trailers, two recent workshop jobs show how we help customers with replacement parts and fitting. One involved a trailer jockey wheel replacement and a worn coupling head. The other involved supplying a wheel and making a practical mounting arrangement for a spare.

New lockable trailer coupling head and replacement jockey wheel assembly fitted at Sleaford Trailers

Trailer jockey wheel replacement and a worn coupling head

A customer brought his trailer to us for a service and mentioned that the jockey wheel was extremely stiff to use. He asked us to fit a replacement, which we did.

During the service, we also checked the coupling head using a new tow ball. This revealed excessive wear that would have worsened with continued use. We fitted a new, lockable coupling head from our stores.

The customer’s original concern was the jockey wheel, but the service identified another component that needed attention. Replacing both items addressed the reported problem and the wear found during inspection.

Choosing a replacement jockey wheel or trailer coupling

A replacement needs to suit the trailer and its existing fittings. A photograph can help us understand what is fitted, but it may not provide everything needed to establish compatibility.

For a jockey wheel enquiry, send photographs of the complete assembly and clamp, together with any visible size or manufacturer markings. For a coupling enquiry, include clear pictures of the coupling head, its mounting and any identification plate or stamped information.

If the coupling is worn, damaged or you are uncertain about its condition, contact us to discuss an inspection. The check described in this job was carried out at our workshop; it is not a guide to assessing coupling safety yourself.

Supplying a trailer wheel and making a spare-wheel mounting

A second customer had recently bought his trailer and brought it to us for a service. The trailer did not have a spare wheel, so we supplied a new wheel and fitted it to the trailer. The wheel we removed then became the spare.

There was no fixture to hold the spare on the trailer. We used a length of galvanised box section from a redundant frame, added packing pieces and a top hat bracket, and secured the wheel to the ladder rack.

This was a mounting arrangement made for that particular trailer. If you need a spare wheel or carrier, contact us to discuss the wheel and the available mounting points; the same arrangement will not necessarily suit another trailer.

What to send when enquiring about trailer parts

The more clearly we can identify the trailer and existing component, the easier it is to discuss suitable replacements. Please send what you have, even if some details are unknown:

  • Trailer make and model, plus gross weight if known.
  • The name of the part you need and a description of the fault or damage.
  • Clear photographs of the part, its fittings and any labels or markings.
  • For wheel enquiries, the tyre size and photographs of the existing wheel.
  • Whether you want to enquire about parts supply, workshop fitting or both.

We may ask for further measurements or need to see the trailer before confirming a suitable part. Availability depends on the item required. Please check with us before travelling to collect parts or bringing a trailer to the workshop.
