A pallet lorry that starts dragging, rattling or marking the floor usually has one problem at the centre of it - worn wheels. If you need to know how to replace pallet lorry wheels, the job is usually straightforward, but only if you identify the correct wheel type, pin size and bearing arrangement before you start. Get that part wrong and you can lose more time than the repair saves.
For most warehouses and workshops, wheel replacement is basic maintenance rather than a major repair. A pallet lorry with flat-spotted or cracked wheels puts extra strain on the operator, struggles under load and can damage floors or pallets. In busy operations, that turns into lost time quickly. Replacing wheels at the right point is cheaper than pushing a damaged lorry until it fails completely.
When pallet lorry wheels need replacing
The signs are usually obvious once you know what to look for. Polyurethane can split or chunk away, nylon can wear down unevenly, and rubber can harden or crack with age. Steer wheels often show wear on the outer edge first, especially on lorries used for frequent turning in tight aisles. Load wheels underneath the forks tend to suffer from impact damage, bearing wear and flat spots.
You may also notice the pallet lorry pulling to one side, sitting unevenly or becoming harder to start under load. Noise matters too. Grinding, squeaking or a rough rolling feel often points to damaged bearings rather than just surface wear. If the frame, fork tips and hydraulic unit are sound, replacing the wheels is normally the sensible fix.
Before you replace pallet lorry wheels
Do not order on appearance alone. Pallet lorry wheels vary by diameter, width, bore size, axle or pin diameter, hub length and bearing type. Even lorries that look similar can use different parts. The fastest way to get it right is to check the model details if available, then measure the existing wheels and hardware once removed.
You will usually be dealing with two wheel positions. Steer wheels are the larger wheels under the handle end. Load wheels are the smaller tandem or single rollers fitted near the fork tips. Some lorries use clip pins, some use roll pins, and some use threaded axles or retaining brackets. That means the removal method can differ from one pallet lorry to the next.
Material choice matters as well. Polyurethane wheels are common because they roll quietly and protect finished floors, but they can be less tolerant of sharp debris or harsh impact than nylon. Nylon wheels suit heavier duty use and rougher conditions, though they can be noisier and less forgiving on delicate floor surfaces. There is no single best option - it depends on the floor, load, frequency of use and operating environment.
Tools and preparation
Most wheel changes need only standard workshop tools. In many cases, a hammer, punch, circlip pliers, spanners, sockets and a suitable jack or blocks are enough. You may also want penetrating oil if the pins have not moved for years, plus a vernier or caliper for accurate measurement.
Work on a clear, level floor and make sure the pallet lorry is empty. Lower the forks fully, isolate the lorry from use and support it properly before removing any wheels. Never rely on the hydraulic unit alone to hold the lorry in position while you work.
A quick photo before disassembly helps. It gives you a reference for washers, spacers and pin orientation, which is useful when several similar parts are on the floor at once.
How to replace pallet lorry wheels step by step
The exact method depends on the lorry, but the sequence is broadly the same.
1. Lift and secure the pallet lorry
Raise the relevant end of the lorry enough to take the weight off the wheel assembly. If you are changing steer wheels, support the rear end near the steering yoke. If you are changing load wheels, support the forks safely so the wheel pins can be removed without the assembly binding.
Stability matters more than speed here. A pallet lorry shifting off a block halfway through the job is an avoidable problem.
2. Remove the old wheel retaining hardware
For steer wheels, remove the axle bolt, pin or retaining clips according to the design. On load wheels, drive out the roll pin or remove the axle fixing that passes through the fork bracket and wheel assembly. Corrosion and dirt often make this the slowest part of the job.
If a pin is seized, apply penetrating oil and give it time. Excess force can distort brackets or mushroom the pin head, which makes removal harder. In older lorries, it is often worth replacing worn pins, clips and bearings at the same time rather than reusing borderline hardware.
3. Remove the wheel and inspect nearby parts
Once the retaining hardware is out, slide the wheel free. If it resists, check for hidden circlips, washers or a burred pin. Do not force the wheel out against the fork bracket if the fit feels wrong.
Inspect the axle, brackets and mounting points before fitting the new part. A new wheel will not solve a bent fork bracket or badly worn axle. Check bearings for roughness, spacing sleeves for wear and the mounting hole for elongation. If the wheel has failed because the bearing collapsed, make sure the surrounding components have not been damaged as well.
4. Match the replacement properly
Compare the old and new wheels side by side. Check diameter, width and hub length first, then confirm the bearing arrangement and bore size. A few millimetres out can create side load, poor tracking or interference with the bracket.
This is where trade buyers often save themselves repeat downtime by sourcing from a supplier that lists dimensions clearly rather than relying on generic descriptions. If you are replacing only one wheel in a pair, bear in mind that uneven wear can affect handling. On heavily used lorries, replacing paired wheels together is often the better maintenance decision.
5. Fit the new wheel
Clean the axle or pin before refitting. Light surface contamination should be removed so the new bearing seats correctly. Then install the new wheel with any original spacers or washers in the same order they came off.
Do not over-tighten if the design uses a bolt-through axle. The wheel should rotate freely without excessive side play. If the wheel binds as soon as the fixing is tightened, check the spacer stack, hub width and bearing fit rather than forcing the assembly closed.
6. Refit the retaining pin or fixing
Install the new or reused fixing securely. Roll pins should be driven in square, clips should seat fully, and threaded fasteners should be tightened to a sensible level for the design. If the lorry uses locking hardware, replace it if worn.
This part sounds simple, but poor retention is one of the easiest ways to turn a small repair into a failed lorry on shift.
7. Test before returning to service
Lower the lorry and roll it unloaded first. Check that the wheel turns smoothly, tracks properly and does not rub on the bracket. Then test with a sensible working load in a controlled area.
Pay attention to steering effort, fork height, wheel noise and straight-line movement. If the lorry still drags or feels uneven, the issue may not be the wheel alone. Damaged bearings, bent linkages or hydraulic imbalance can produce similar symptoms.
Common mistakes when replacing pallet lorry wheels
The most common mistake is ordering by visual match instead of measurement. The second is replacing the wheel but not the failed bearing or damaged pin that caused the original problem. Another frequent issue is mixing wheel materials across the same lorry, which can alter handling and wear characteristics.
There is also the question of repair versus replacement. If the pallet lorry has severe frame wear, cracked forks, a failing pump unit and worn wheels, fitting new wheels may only delay a larger breakdown. On the other hand, if the lorry is structurally sound, wheel replacement is usually a cost-effective maintenance job.
Steer wheels and load wheels are not the same job
Steer wheel replacement is often easier because access is better and the assemblies are larger. These wheels influence manoeuvrability, operator effort and overall tracking. If the lorry feels heavy on turns, steer wheel wear is a likely cause.
Load wheel replacement can be more awkward because space is tighter and dirt tends to build up around the fork-end fittings. These wheels carry direct fork load and see regular impact from thresholds, pallet entry and uneven floors. If the forks sit low, hesitate when entering pallets or feel rough under load, start there.
Choosing the right replacement wheels
The correct wheel depends on the application, not just the dimensions. For cleaner warehouse floors and lower noise, polyurethane is often the practical choice. For heavy-duty use, abrasive conditions or where impact resistance matters more than floor finish, nylon may make more sense.
If you are managing a mixed site with warehouse, yard edge and workshop traffic, wheel life may depend as much on the route as on the lorry itself. That is why repeat failures should prompt a look at floor condition, load practice and whether the wheel material suits the environment. A good parts supplier should help you match specification to use, not just sell a nominal replacement.
If you are unsure, it is worth checking the wheel dimensions, bearing type and pallet lorry model before ordering. It keeps the repair simple, avoids unnecessary downtime and gives you a better chance of getting the lorry back into service on the first attempt.
