Daniel's post refers to the 400 suspension units that have shock absorbers incorporated in them . They just need to be filled to the correct level with Shock oil and check regularly as the seals often leak.

The 403 use the same alloy body as the 400 and the Penrite steering box lube can be used but its very difficult to fill as it does not really flow.
I suggest you remove one of the large plugs on the side of the unit and clean the unit out the best you can . You will need the correct ring spanner to undo the plug. I found that using a large "G" clamp to hold the ring spanner on to the large plug stops the ring spanner from slipping off and damaging the plug. They are very tight !!!
To fill with the steering box lube, as Daniel mentioned make sure you clean the outside of the body thoroughly , then using a large oil syringe force the lube through the small plug on the outside of the body , that is after removing the filler plug at the top to allow the air to escape.

If they continue to leak they will require removal from the chassis and a complete strip down with new seals and probably bearings. But worth a try first .
