Ownership Tips

Invaluable knowledge and tips

Steering box problems

If the car is physically hard to steer and driving is a tiring experience, or the steering does not self-centre you may wish to identify and rectify the possible causes.

The first thing to check is that the kingpins are in good order and everything is properly lubricated. If the steering is still stiff and ‘sticky’ then it may mean that you need a new steering worm and nut fitted.

If there is free play in the straight-ahead position this cannot be overcome by adjustment and the steering box is in need of overhaul.

Check your car is not a fire risk

Older classics with original wiring can be a major fire risk and you should first check car’s service history to see if it has been recently rewired.

Also, examine the wiring for modern fittings in the car where it is visible, for example the connections to the dynamo or the horn wire at the base of the steering column.

If you believe that your car has any original wiring you should consider having it safety checked or rewired by our specialists.

Correct way to
fit hub bearings

The front hubs on pre-war cars are located on the axle by the outboard bearing and, as a result, this has to do a lot of work so it is important that this is fitted correctly.

The grease cap and its retaining nut keep the bearing in position, and it is most important that this clamps the bearing tightly when fitted.

Be aware that if the hub is refitted by tapping on the outer rim of the hub the bearing will have a tendency to ‘walk’ out of the hub, and may not be pulled back in by the grease cap and ring nut.

Avoid An Engine Disaster

Proper lubrication of moving parts is vital for longevity and efficiency, the pre-war Rolls-Royce and Bentley engines is no exception. The design of this engine needs to be understood to avoid a loss of lubrication which might result in a very costly overhaul. An apparently healthy oil pressure may not indicate a healthy engine.

If the condition of the bearings in your engine is unknown a bottom end decoke could be a very worthwhile operation.

shock
absorbers

In the final development of the Rolls-Royce hydraulic shock absorber, which continued to be used extensively after the war, the performance is controlled by a lever under the driver’s control enabling them to vary the ride to suit the driving conditions, with the effectiveness of the shock absorbers increasing with speed.

Earlier versions of the Rolls-Royce hydraulic shock absorber lack the ‘Ride Control’ function of the later units but perform an equally critical function.

Servicing
is vital

Reasons to have your car serviced regularly:

1. To ensure that your car is safe and roadworthy.
2. To ensure that your car is running efficiently.
3. To check for signs of deterioration.

When it comes to low annual mileage little or lack of use can be just as damaging, with one-shot systems draining, lubricants deteriorating, fuel systems issues due to the properties of modern petrol, and tyres perishing or suffering from standing in one spot.
