Manual transmission and diff rebuilds
IN-HOUSE MANUAL GEARBOX & DIFF REBUILDS IN DARWIN

Noisy gearbox, jumping out of gear, or a whining diff? Our workshop rebuilds manual transmissions and differentials in-house for 4WDs and commercials, so you deal with one team from diagnosis to handover.
A rebuild can be a cheaper option than a replacement unit. Where a rebuild doesn't stack up, we can supply a used or reconditioned gearbox or diff from our Winnellie stock or our network of 300+ wrecking yards across Australia.
When you bring your gearbox or diff to Darwin 4X4 Centre, a typical rebuild covers:
- Strip-down and inspection
- Worn bearings and seals replaced
- Gears and synchros checked and replaced as needed
- Diff setup checked to specification
- Refilled with oil to manufacturer spec
Not sure if it needs a rebuild? Get in touch or call (08) 8984 4804 and we’ll talk you through it. Need a replacement instead? Browse our gearboxes and diffs.
