Common jobs for Oamaru drivers
Waitaki dairy and the North Otago sheep and cropping farms keep Oamaru workshops busy with utes. Hilux, Ranger, Colorado and D-Max rear diffs that have towed across irrigated paddocks all season, with Land Cruiser units from the upper Waitaki stations. Low speed towing wear on the carrier is the common finding, and the exchange model suits a farm that cannot spare the ute for long.
Any mechanic in Oamaru 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 Oamaru
I am on a rural address outside Oamaru. Does that change anything?
Rural delivery usually adds a working day each way, and the courier needs a clear pickup point for the old unit on the way back. Tell the team the address is rural when you order and the freight is booked to suit.
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.
