apparently the front wheels on my car need adjusting the front right tyre is wearing too quickly on its inner side. Professional measurement shows that both camber and toe-in are different on each wheel, and the measurement indicates that at least the camber on the front right one needs correction. Looking at the axle geometry I was not sure however where the camber actually is adjusted, so I would be very interested to learn the recommended way.
The front suspension ( as standard) is non-adjustable for camber.
MOSS and Revington sell adjustable top links which can get you out of trouble if the front end is seriously bent or out of alignment. However, they are expensive, and before you get too deep into front end problems, it's worth checking the state of the rear, because the rear ride heights can seriously affect the camber and castor at the front.
If you can get the car on a flat surface ( or put spacers under the wheels to make them all level) then you will find that jacking one rear corner at a time and measuring the front cambers with a spirit level wil show you whats going on.
If you have one front tyre that's wearing and all of the front joints are sound then you may find that the cause is a rear spring that has gone soft.
that is a very good hint and one I would not have thought of. It occurs to me that perhaps the right rear spring has gone softer than the left one because of the ballast on the drivers side (its the front right tyre that is wearing more). The chassis itsself looks fine to me, but of course the rear springs are probably (very) old. From experience, is re-tempering an option or is replacement best?
In both cars that I've rebuilt the rear springs were not re-usable.
They all had lost temper and had broken leaves, as well as shot bushes and frozen bolts at the front. Sometimes swapping springs or individual leaves between sides can even things up but this is a lot of work, and these springs are 50+ years old now.
TT4016 from MOSS will fit but are far too soft as standard. I know that an extra 2 and a half leaves and +2" ride height is too much, so I'm using an extra one leaf and +1.5" on the Warwick this time round.
Oh, and do check that both front suspension units have the same size aluminium spacer and number of rubber washers fitted.
many thanks for the very good advice, now there are a number of things for me to check. I believe the route to go is for new springs with an additional leaf which I might get fabricated locally. Certainly the springs should not be too soft, thinking of the weight of two possible passengers in the back which a TR3 does not have to take. Its a good thing that the spares are available.
