FELK Engineering are RMS certified repairers and have been repairing trailers from all manufacturers for locals of the Hunter region since 1961.

Repairing trailers has provided us with valuable insight into designs and components that will enhance performance. We take road safety seriously and take every opportunity to improve the reliability and safety of our own product for our Australian customers.

We perform the following repairs on trailers:


We also stock a range of new and custom trailer parts, if replacing is a better option than repairing.

Repair standards and expectations

FELK Engineering takes repairs very seriously, and for good reason. We have worked incredibly hard within the industry to build a trusted reputation. When working with FELKS, you’ll know that our trailer repairs go above and beyond.

We will also inspect the following:

  • Springs
  • U-bolts (should always be replaced when springs are replaced)
  • Brake pads
  • Bearings
  • Wheels
  • Tyres (flat spots & chunks)


Our repairs are performed to the highest of standards. If we believe your trailer or part is beyond repair, then we will tell you upfront, because we don’t want to waste your time or your money.

Repair Example - Crossmember

Crossmembers are particularly susceptible to rust damage. We often replace these with our superb quality, hot dipped galvanised crossmembers.



Repair Example - Lights & Mudguard


In the photo below, you can see that the rear crossmember has completely snapped off from the chassis, also the tail light and LH mudguard are in need of attention.


A new crossmember has been installed, new lights fitted, and the mudguard has been replaced with high quality Australian steel.

Trailer Repair FAQ

  • What happens if I require repair and my FELK trailer is under warranty?

    If there is any problem with your trailer during the warranty period, then your repair is performed free of charge (assuming the fault is not a result of misuse).

  • How long does the average repair take?

    Approximately 3-4 days.

  • Do you provide a warranty on the repair?

    We provide a 12 month warranty on the repair (with exceptions). Example of an exception: Internal rust not visible at the time of repair in a different section of the trailer, resulting in undue stress, an overload of the repair, and structural failure.

  • Will my trailer be roadworthy afterwards?

    Yes. Our number one priority is safety, thus we ensure that all trailers that leave our workshop are in roadworthy condition.

  • Do you provide on-site repairs for the trailers of industrial and mining clients?

    No. We require access to our own tools and machinery and require all repairs to be performed at our Warners Bay workshop.

  • Will you tell me if my trailer is beyond repairing?

    Yes. This is something we do quite frequently.

    Many times, it does not make economical sense to repair a trailer that is very old and in poor condition. In this event, we will list all available options, such as comparing total cost of repair versus purchasing a new trailer.

  • How much experience does FELK have with trailer floors?


    We’ve been repairing box trailer floors for over 50 years.

    It can be quite a challenging job. There is great variation in sizes between manufacturers.

    For example, a FELK box trailer may be 8×5 ft internal measurement however another manufacturer may advertise a 8x5ft, yet the measurements are external measurements. It is critical to order the right cut sheet of metal.

    If the original sheet has been welded to the floor, this will require grinding to remove it from welds, as well as cleaning out the rusts and burrs.

    • The most common causes of floors requiring repair are:
    • Rust issues
    • Holes
    • Corrosion from other sources (we have seen battery acid spilled on a trailer floor)
    • Buckling (the floor can warp)
    • Upgrades (increasing thickness for heavy-duty, or changing the style of the floor from galvanized to checker plate).
  • How do I know when my electric trailer brakes require repair?

    This is very difficult to judge inside the tow vehicle on some of the lighter loads.

    The larger, heavier loads will cause you to apply more pressure on your brakes and this can be judged by the heat of your brakes on the tow vehicle (car) when you check your wheels.

    If your trailer brakes require adjustment or repair you will feel extreme heat radiating off the brake components on the tow vehicle (car).
