Description
Koyo/JTEKT wheel bearing for adjustable Land Rover hubs
This Koyo/JTEKT wheel bearing (RTC3429G / STC4382) is a tapered roller bearing for adjustable Land Rover hub assemblies. It fits Defender, Discovery 1 and Range Rover Classic front or rear hubs where this bearing type is specified.
The bearing is supplied with its matching race and should be fitted as a matched pair. It is suitable when replacing worn, noisy or rough wheel bearings, or when rebuilding a hub during axle, swivel, seal or brake work.
When fitting, press or drive the old race out fully, fit the new race supplied with the bearing, pack the bearing with suitable wheel bearing grease and set the hub adjustment correctly. It is usually worth replacing the hub seal, lock washer and any disturbed fixings while the hub is apart.
If you prefer the better-known Timken option, see our Timken RTC3429G wheel bearing. For a fuller Defender hub rebuild, browse our wheel bearing and hub kits.

Buy with confidence: all new parts sold by Twinwoods 4x4 include at least 12 months manufacturer warranty against defects in materials and workmanship under normal use.
Some products and brands may include a longer warranty period where this is provided by the manufacturer. Where applicable, this will normally be stated on the individual product page or covered by the manufacturer’s own warranty terms.

For certain components, proof of professional fitment may be required.
Warranty claims may require the part to be returned for inspection and/or supplier testing before the claim is accepted. Any advance replacement is discretionary.
Warranty remedies relate to the part itself, meaning repair or replacement, or refund if those are not possible. Warranty does not cover labour, removal or refitting, diagnostics, consumables, travel or other incidental costs.
This warranty is in addition to your legal rights and does not reduce those rights.
