Hello again and I have remembered something which may be helpful:
A Man called Mark A Paget wrote a very interesting article called something like:
Death Through Dehydration
which was about Mini - Moke - Metro and MGF suspension
Below is an extract:
Rover 100 and MG-F are unusual for popular small cars. Despite being produced in the 1990s and early 2000s, they still have grease points. Virtually all their competitors had ‘sealed

for life’ systems. Therefore industry and public attitudes had already moved away from physically lubricating any vehicle. The result of course is obvious. As both models continue to use the same design of pivot pin as the others, the same problems can be expected.
Lack of lubrication results in;
 premature wear to bearings (bushes),
 pivot pin wear,
 thrust face erosion at the end of each arm, and
 after prolonged periods, erosion of the arm’s internal faces to which the bearings mount.
This may present itself as noise, excess free play, seizure or collapse (catastrophic failure). Even with the most fastidiously assembled arms, lubricant flow can be haphazard. Countless arms can be found where lubricant will only move to one end. Despite the vast array of non-genuine pins (with their wildly varying tolerances), none have improved the lubrication system. A simple alternative for rear units would be to introduce another nipple and drilling at the pin’s inner end. This would of course increase the chance of adequate grease distribution.
Front arms fair no better but are not serviced on an exchange basis. Applied load tends to mask problems such as free play. Ignorance and avoidance of the problem creates lack of demand, hence lack of supply.
Unlike many other suspension components, there are no aftermarket reproduction arms. The possible exception being the mystery brand Chinese made rears for 13” Moke. However these at best ‘resemble’ the genuine part. Choke (Chinese-Moke) parts are manufactured to No accepted International Standard. Sellers and stockists of course recommend their product but buyers tend to be limited to the extremely tight-fisted. ‘Cheap’ Moke owners are an acknowledged social phenomenon.
The only effective answer is to attentively lubricate the original factory system. Ideally this would occur every 1000 miles with an extreme outside limit of 3000 (1500 > 5000 Km). A well serviced Mini can be easily expected to be on its original rear pins and arms after forty years. If not for pin failure, Big wheel Moke could match this. Though finding a well serviced example of either car can be extremely difficult. If not for the following problem, front arms could be well expected to outlast the vehicle. However the service and repair of this next component is beyond that of the owner/driver.
A second area of concern is the knuckle joint
I am not clever enough to be able to send a link, but you should be able to Google search it.

He is from your part of the World, by-the-way!  He is certainly a World-Class expert on Hyrdragas and Hydrolastic suspension systems.  I used to sell Materials Testing Systems, and he certainly knows what he is talking about re springs and suspension systems. A VERY useful bloke to meet-up with if you can. Pleae pass my thanks for his advice (Which steerd me towards a metal-sprung TF rather than a Hydragas MGF.
