When I have time on my hands I invariably gravitate towards the bicycle, garage or garden. Like most people at the moment, time on my hands is something I have in an abundance. I’d already done a big ride the day before, the garden was looking OK so the garage was next point of call.
The recommended service interval for changing the differential and swivel oil is 6,000 miles (10,000 Kms). As the differentials and universal joints are all new to the vehicle, an earlier service is advisable.
The oil used to lubricate the differentials and universal joints (the parts inside the swivel housing) is called EP90; the EP standing for Extreme Pressure and is designed to provide a metal to metal barrier between gears. (SAE90 doesn’t provide this protection but is the same viscosity)
When new, these large mechanical components “wear in” relatively quickly, the oil fast becomes heavy with tiny metal particles and becomes less effective at providing the metal to metal barrier.
Changing the oil at the recommended frequency ensures component longevity.
FRONT AXLE DIFFERENTIAL AND SWIVELS
Starting with the drivers side swivel housing….
I didn’t take any pictures of draining the passenger swivel housing. With all of the oil drained out, its time to fill everything back up.
The axle takes 1.7 litres of EP90 and each swivel takes 0.7 litres. It’s not essential to be all that exact when filling up as these volumes equate to the oil reaching the bottom edge of the respective filler holes. Once you see it flowing back out, you’ve added enough oil. This is the same with the rear differential and both gearbox cases.
REAR AXLE DIFFERENTIAL
This is a bit quicker as there’s no steering swivels. The rear axle works a lot harder than the front. This is because in normal driving conditions, the Land Rover is driven in rear wheel drive only. The front differential is just idling as it’s driven around by the road wheels. There’s no load applied unless 4 wheel drive is selected.
Last job (after washing my hands and making a cup of tea) was to fill out the service record in LGLs book and dial in the next differential and swivel service.
Job done 🙂
