Exchange diffs and diff repairs for New Plymouth

Common jobs for New Plymouth drivers
Trade utes and vans from the energy sector sit alongside dairy farm utes in New Plymouth workshops. Ranger, Hilux and Colorado rear diffs with high mileage and a lot of towing are the likely swaps, with BT-50 and D-Max units in the mix. Fleet operators tend to value the one visit fit an exchange allows, because a ute waiting on a rebuild is a ute not earning.
Any mechanic in New Plymouth can fit an exchange diff head. The unit arrives with fitting notes, the ratio tagged on the housing and the oil specification, and the team in Christchurch is on the phone to your workshop if anything about the model needs checking. For a repair to your own unit rather than an exchange, the diff travels to Christchurch on the courier and back, freight free, while the vehicle stays with your local workshop.
Ordering from New Plymouth
How long will my vehicle be off the road?
Only as long as the swap itself. The exchange unit arrives before anything comes out of your vehicle, so there is no waiting on a rebuild while the ute sits on stands.
Can you quote before I order?
Yes. Send the rego and a line about the noise or fault through the enquiry form and the team confirms the right unit and the price, core charge included, before you commit to anything.
