So with the hub and strut dismantled I set about cleaning things up. The lower part of the hub carrier mounts to the rear suspension arm with a simple long king-pin design. It was all in good condition with no wear on the kingpin or bushes, but either end is sealed by these discs which are like mini-pistons and have three sprung piston-rings to provide the seal. One was ok, the other the rings were seized.
After a good soaking and cleaning the sealing rings freed up. I cleaned everything up and painted the solid disc for protection.
Here you can see the rear suspension arm and where the hub carrier lower pivot king-pin mounts.
And the cleaned up parts, kingpin, thrust washers, sealing rings and big suspension bolt!
With the hub carrier cleaned up and painted, king-pin reassembled and greased from the bottom (on it's side for access in this photo). The bolt inserted just to keep the sealing plates in place whilst greasing.
Cleaned and painted strut re-assembled and back in the place. I used the original strut top mount which actually seems to be in good condition. Spring was media blasted and painted in a close match to the original green.
View of the cleaned and painted hub carried bolted up. You can see the handbrake cable mounting lug - all very simple.
