Front lower wishbone spherical joint circlip size and supplier?

[john milner]

I did a Know Your Seven session at Caterham years ago. The man (not a Caterham employee) running it said to add a drop of 3 in 1 occasionally. I followed this advice and mine lasted over 20 years & 82.000 miles before getting an advisory. It makes sense to me to lubricate when a bearing has aged a bit but might not be best from new.

It does seem odd that this joint does not have some kind of cover to reduce road grime and weather.

A bit difficult to have an effective cover. You can get covers for rose joints but they are similarly difficult to protect and hence they are rarely used.

Some joints will fail an MOT because of small hole or perishing but this joint has nothing. Surely something is better than nothing in most cases.
