Just installed a lift kit on your Hilux, Ranger, Triton or D-Max and now the thing vibrates on take-off? You’re not imagining it. A common driveline issue appears once you change tailshaft angles, and it has nothing to do with wheels or tyres.
Explore our custom tailshaft builds or book a driveline inspection to fix the shake properly.
What Happens When You Lift a 4WD
Lifting your 4WD changes more than just ride height — it also alters the angle between the transmission, tailshaft and differential.
The tailshaft is now operating on a steeper angle, which:
The tailshaft is now operating on a steeper angle, which:
- Increases strain on U-joints and centre bearings
- Causes binding during suspension travel
- Leads to vibration and premature wear if left uncorrected
Symptoms of Incorrect Tailshaft Angles
These are the most common driveline problems we see after a suspension lift:
-
Vibration on take-off
Often starts around 10–20 km/h and smooths out at cruising speed. -
Driveline noise at speed
A humming or droning sound, especially under load. -
Premature U-joint wear
Lift kits create sharper operating angles, wearing joints faster. -
Leaking centre bearing or slip yoke
Misalignment and vibration can damage seals.
Most owners assume it’s a wheel or tyre issue — but it’s usually not. The problem is often buried deeper in the driveline.
How to Fix It (Without Undoing Your Lift Kit)
Good news: you don’t have to reverse your suspension mods to get smooth driveline operation again.
Solutions we use at GJ Drivelines include:
Solutions we use at GJ Drivelines include:
-
Centre bearing spacers
Helps correct tailshaft angle in two-piece shafts with centre support bearings. -
Diff drop kits
Brings the diff housing back to a more neutral alignment. -
Custom-length tailshafts
We build tailshafts tailored to your lift, suspension travel and torque demands. -
Double cardan joints or CV tailshafts
Allow for greater angle variation and smoother rotation under load. -
Pinion angle correction
Leaf spring shims can realign the diff pinion to suit your tailshaft geometry.

When You Need a Custom Tailshaft
Your factory tailshaft wasn’t designed for modified suspension geometry. In many cases, it’s just not long enough or strong enough to cope with increased angles and articulation.
-
Long-travel shocks can stretch the shaft too far
-
Stock slip yokes bottom out or bind under load
-
Torque loads exceed OE part tolerance
At GJ Drivelines, we design and build custom shafts to suit your:
-
Lift height
-
Suspension type
-
Power and torque output
-
Daily use vs off-road flex priorities
Whether you’re chasing flex or just want smoother daily driving, we’ll build a tailshaft that fits your lift kit and your use case.
Book a consultation with our workshop and get rid of the vibration for good.
