Front axle/steering wobble

[Robert Leigh]

This last week, the RP has had a fair bit of use. 

One odd thing that has happened twice now is that i have had to drive over pot holes as i brake onto a junction. This put the front of the car into a very odd wobble. Almost like the axle is oscellating on the spring shackles. This then sets the steering wheel wobbling also. 

Ive studied all components carefully and can find no faults

Its a semi girling axle. 

Does anyone have any ideas? 

King pins are less than 1000mile from being done.

The steeringg box has bugger all play.

On an Austin Seven I have had this problem. The car concerned was well worn, before the days when people restored them, but it turned out to be king pins wobbling in the axle, so I suggest checking the axle eyes. On my present Vintage Riley the same problem turned out to be sagging front springs. A previous owner admitted to me that he had sold the car because he could not solve the problem. My advice is check everything concerned with front axle and steering geometry, and make sure that the front shock absorber is working correctly.
