Freelander 1 IRD Unit Exchange

IRD Unit Exchange for the Freelander 1: a remanufactured IRD on an exchange basis, supplied ready to fit.

The IRD, or power transfer unit on the later cars, takes drive from the gearbox to the propshaft. On the Freelander 1 it fails because the viscous coupling in the propshaft line seizes and fights it, and the commonest cause of that is one tyre different from the other three. On the Freelander 2, Evoque and Discovery Sport the unit runs hot, the oil breaks down, and the bearings and seals go. Every unit here comes with the advice that stops it happening again, which is four matching tyres at matching pressures and an oil change the factory schedule does not ask for. The Freelander 1 runs an IRD, a viscous coupling and a rear diff in one line, and all three live or die by whether the four tyres match.

Fitting

Labour guide: about 5 hours. Land Rover changes specification mid production, often by VIN rather than by model year, so send the VIN or the registration with the order and we confirm the part against the build data before anything leaves. It takes two minutes and it is the difference between a part that fits and a return. We are an independent Land Rover specialist and parts supplier. We are not Land Rover or Jaguar Land Rover and are not appointed by them; the model names are their trademarks and are used here to describe fitment. Everything we sell is chosen for vehicles that actually get used: towed with, loaded, driven through water and parked in fields, rather than for the brochure.

Which version to buy

Remanufactured is stripped to the casting, measured, rebuilt with new bearings seals and wear parts and rig tested, with a surcharge refunded on your old unit. New Unit is a brand new unit rather than an exchange, for when your old one is past rebuilding or you cannot be without the vehicle while we assess the core.
