Tyrex Manual Locking Hubs Nissan Terrano I, 27 Splines
Tyrex manual locking hubs with 27 splines for the Nissan Terrano I and the King Cab version. The manufacturer lists them as an AVM429 equivalent. Manual operation means the state of the front axle drive is always visible on the hub, with no automatic mechanism to trust.
Tyrex Manual Locking Hubs, 27 Splines — Nissan Terrano I
On older Terranos the hubs are usually the weakest link in the front driveline — automatic units have a habit of not engaging precisely when four-wheel drive is genuinely needed. The manual version solves that in the simplest possible way: a dial on the hub that is either in LOCK or it is not.
This Tyrex set has 27 splines and is intended for the first-generation Nissan Terrano, including the King Cab variant. The manufacturer catalogues it as an equivalent to the widely used AVM429 hubs, so fitment can also be checked against that reference.

Key benefits
- Unambiguous engagement — the hub position is visible at the wheel, so there is no guessing whether the front axle is driving.
- No automatic mechanism — fewer parts to refuse to work off road or in the cold.
- Front driveline disconnected in 2WD — unlocked hubs stop the shafts and axle components turning, reducing wear in everyday driving.
- Confirmed AVM429 equivalent makes it easy to compare against whatever is currently fitted.
- 27 splines — a specific spline count you can verify on your own driveshaft before buying.
Technical data
- Catalogue code: TY12572 (Tyrex)
- Type: locking hubs, manual operation
- Spline count: 27
- Application: Nissan Terrano I, including the King Cab version
- Equivalent: AVM429
- Weight: approx. 2 kg
Who it is for: first-generation Terrano owners whose automatic hubs have started failing or have already been removed. It is also a sound choice when preparing a vehicle for working use and expeditions, where a predictable driveline matters more than engaging four-wheel drive from the seat.
Fitting notes
Count the splines on your driveshaft before ordering — Terranos appear with different configurations, and 27 splines is a specific rather than a universal specification. Hubs should be replaced in pairs so the front axle drives symmetrically. Manual hubs require stepping out of the vehicle to lock and unlock the drive, which is the deliberate trade-off for certainty of operation.
Why it is worth it
- A simple mechanical system instead of an automatic one that can let you down off road.
- Concrete specification: 27 splines and a confirmed AVM429 equivalent.
- Matched to the Terrano I rather than sold as a universal substitute.

Frequently Asked Questions
How many splines do these hubs have?
27. It is worth counting the splines on your own driveshaft first, as Terranos appear with different configurations.
Which vehicles do they fit?
The manufacturer lists the first-generation Nissan Terrano and the King Cab version.
Is there an equivalent from another brand?
Yes — the manufacturer catalogues them as an AVM429 equivalent.
How do manual hubs differ from automatic ones?
Manual hubs are locked and unlocked by hand at the wheel and their position is visible on the hub. There is no intermediate automatic mechanism, so the state of the front axle drive is always unambiguous.
