What size is the rear hub nut on a Ford Transit?
The rear hub nut size on a Ford Transit is not universal; it varies by model year and axle configuration. In practice, you’ll commonly encounter a 36 mm hex nut on many modern Transits, but some variants use 32 mm or other sizes depending on the generation and rear-axle design. Always verify with your vehicle’s workshop data or by measuring the nut yourself.
Why sizes vary
Ford Transit production has spanned multiple generations, each with different rear-axle assemblies. The nut that secures the hub onto the axle is sized to match the axle’s bearing carrier and threading, which changes with changes in design, weight rating, and regional specifications. Because of these variations, the exact size can differ even between closely related model years.
Axle type and model year differences
Most newer Transits use a solid live rear axle with a large hub on which a securing nut is threaded. Some older or region-specific builds may use a slightly smaller or differently profiled nut. The safest approach is to confirm from official data for your exact VIN or to measure the nut directly if you’re replacing it.
Common sizes observed
The following sizes cover the typical range you may encounter across different Transit generations, but your exact vehicle may differ. Use this as a reference and verify before tool purchases or replacements.
- 36 mm hex rear hub nut is common on many late-model Transits with standard rear hubs.
- 32 mm hex rear hub nut appears on some older Transits or alternative rear-axle configurations.
- 38–40 mm hex nuts can be found on certain heavy-duty or region-specific builds.
The takeaway is that the safe approach is to confirm the exact size for your VIN using Ford’s service data or by measuring the nut directly.
How to confirm for your specific Transit
To pin down the exact size for your vehicle, follow these steps:
- Identify your Transit generation and rear-axle configuration from the VIN plate or the owner’s manual.
- Check Ford’s official workshop manual (WSM) or a trusted parts catalog for your VIN to confirm the nut size and torque specs.
- If manuals aren’t accessible, measure the nut across flats with a caliper or ruler to determine the correct size.
- When replacing, ensure you use the correct nut type (standard hex or locking nut) and match the thread and locking design to avoid improper seating.
Following these steps reduces the risk of fitting the wrong nut and risking hub or bearing damage.
Summary
There is no single universal rear hub nut size for the Ford Transit. Common sizes observed include 32 mm and 36 mm across flats, with some variants using 38–40 mm in certain configurations. Always verify via VIN-specific Ford workshop data or by measuring the nut, and consult the official torque spec when performing replacement or service.
What is the torque on the hub bolts on a 2019 Ford Transit?
For the 2019 Transit 250, rotor-to-hub bolts typically torque between 70-90 ft-lbs; wheel bearing bolts require 100-120 ft-lbs. Always clean bolt threads and use a calibrated torque wrench to avoid over- or under-tightening. Inspect bolts for damage and replace if necessary.

What size socket for axle nut?
The size of the socket for an axle nut varies by vehicle, but common sizes are 30mm, 32mm, 35mm, and 36mm. It is essential to check your vehicle's specific manual for the correct size, as it can differ between models and may have been changed if the axle has been replaced.
- Common metric sizes: 30mm, 32mm, 33mm, 34mm, 35mm, and 36mm are frequently used, says JustAnswer, Reddit users, Parts Avatar, and Home Depot.
- How to be sure: The most reliable method is to consult your car's owner's manual or a repair manual specific to your make and model to confirm the correct size and torque specifications.
- Socket material: For high torque applications, such as loosening or tightening the axle nut, use a strong, impact-rated socket made from materials like chrome-molybdenum steel to avoid damage to the socket or the nut.
