The Discovery II locates its live rear axle fore-and-aft with two radius arms and laterally with a Watts linkage (two transverse links plus a central pivot housing), not the trailing-arm/A-frame layout of older Land Rovers. Tighten the radius-arm and Watts-linkage fasteners with the vehicle's weight on the suspension (at ride height).

Important Notes
Torque-to-Yield Fasteners
The following fasteners are torque-to-yield (TTY) and must be replaced after removal:
- Cylinder head bolts
- Connecting rod bolts
- Main bearing cap bolts
- Flywheel/driveplate bolts
Engine Variants
The Discovery II was available with two engine options:
-
Td5 - 2.5L inline-5 turbodiesel (most common outside North America)
-
V8 - 4.0L petrol (North American market)
Some torque values differ between engines. Refer to the appropriate section above.
Thread Preparation
- Clean all bolt threads before installation
- Apply fresh engine oil to cylinder head bolt threads
- Use new gaskets and O-rings where specified
