Difference between Ford and Holden Trailer Bearings
Trailer bearings are an essential component of a trailer’s wheel assembly, allowing for smooth and efficient rotation of the wheels. When it comes to trailer bearings, there are two main types commonly referred to as Ford and Holden bearings. Here are the key differences between them:
1. Sizing: The most significant difference between Ford and Holden trailer bearings is their sizing. Ford bearings are generally larger and are also known as slimline bearings, while Holden bearings are slightly smaller. A general rule of thumb is that if a bearing fits over your thumb, it is a Ford bearing, whereas a Holden bearing won’t quite fit onto your thumb.
2. Stud Size: The stud size of the hub determines which bearings are required. Ford and Holden hubs have different stud patterns, and the distance between the wheel studs can help identify the type of hub. For example, Ford hubs typically have a stud-to-stud distance of 68mm, while Holden HT/Early Holden hubs have a distance of 65mm. Holden HQ hubs, on the other hand, have a distance of 72mm.
3. Axle Compatibility: The type of axle used in the trailer can also indicate the type of bearings required. Round 39mm and square 40mm axles usually use Holden bearings, while 45mm square axles typically use Ford bearings.
It’s important to note that while Ford and Holden bearings are the most common types, there are other variations and combinations of trailer wheel bearing kits available. Therefore, it’s crucial to consider the specific requirements of your trailer and consult with a reputable supplier or mechanic to ensure you get the correct bearings for your trailer.
I hope this information helps you understand the difference between Ford and Holden trailer bearings. If you have any further questions, feel free to ask!

Are Ford and Holden bearings interchangeable?
The safest way to ensure that you get the right ones for your trailer is to check the numbers on the side of the inner and outer bearings and order the same ones. Just measure the axle or stub axle behind the wheel. If it is 40mm square or round it runs holden bearings, if it is 45mm square it will run ford bearings.
What is the difference between Ford and Holden stud pattern?
The thread diameter of the wheel studs is different between Holden and Ford, I find this the quickest and easiest way to tell them apart. The Holden hub runs 7/16 inch UNF nuts whilst the Ford hub runs 1/2 inch UNF nuts, and the size of the hex is different (bigger on FOrd pattern).
Can you put Ford bearings in a Holden hub?
Holden bearings have a smaller inner diameter on each bearing than the Ford bearings, hence the Holden axle stubs are machined to smaller diameters. The axle stub determines the required bearing. The hubs or disks will fit either type of bearing.
What size are Holden bearings?
LM (Holden bearings) are rated for 750Kg on a 39mm round axle or 1000Kg on a 40mm square axle. Timken LM bearing kit includes: 1 x Set 6 bearing – 67048 cone & 67010 cup (67048/10) 1 x Set 2 bearing – 11949 cone & 11910 cup (11949/10)
What stud pattern is Holden?
Stud pattern identification
| Type | No. of studs | PCD (inches) |
|---|---|---|
| HT Holden | 5 | 4 1/4 (4.251) |
| HQ Holden | 5 | 4 3/4 (4.75) |
| Commodore | 5 | 4.7813 |
| Ford Falcon | 5 | 4.5 |
Can you use Holden bearings in a Ford hub?
You can have any combination of Stud Pattern (above) with any bearing set (below). E.g. A Ford Stud Pattern Hub with Holden Bearings is very common.
What is the difference between Ford hub and Holden hub?
2) In most cases, Holden studs are 5/16inch whilst Ford are 1/2inch, but whilst rare you can get Ford hubs with 5/16inch studs, 3) If your axle size is 39mm round or 40mm square you should have Holden type bearings. If the axle is 50mm square they should be Ford type bearings.
How do I know what bearings my trailer has?
The easiest way to determine which bearings are used on your trailer axle is to take the hub off and look for the reference numbers stamped into the metal of both inner and outer bearings. If the bearing numbers are unclear, the next best solution is to take measurements of both bearings. This is the bearing itself.
How to tell the difference between Ford and Holden trailer hubs?
The Holden bearing is slightly smaller and won’t quite fit onto your thumb. The main thing is measuring your stud size. Ford hubs measure 12.4mm and Holden hubs measure 11mm. This is the major factor for determining if you require a Ford or Holden wheel bearing trailer kit.
Are all trailer bearings the same?
The hub holds 2 bearings, the inner bearing (inside the hub flange, closest to the trailer center), and the outer bearing. Since one size trailer wheel bearing does not fit all, to determine the correct size wheel bearing for your trailer, you’ll have to take apart the hub.
