Rear shock absorber advice

On close inspection of my Traveller rear suspension I have a leak from the rear shock absorbers, I would like to know if there is a kit for overhauling them as I see shock absorbers on ebay listed as refurbished so ideally I would like to do my own.

Where is the leak from?
Is it the lever pivot, the top gasket or the valve at the bottom?

I've seen someone (on YouTube I think) dismantle a damper for refurbishing?
My rear dampers are inclined to leak from the shaft so obviously need attention but although the level drops the actual 'damping part' ,the pistons, remain covered in oil and still damp!

I submitted a post back in 2014 on how to repair the dampers at home but when the website was updated all the photos were lost.
Here is a link to how I did it in another place

It looks like my leaks are from the shaft area and because of this I need to deal with the leaks before deciding weather the leaf springs are tired or not. I was going to upgrade the oil in the damper pots as Ive done in my Convertible so a clean up and overhaul is called for.
This is a fabulous "how to do" link thank you

Whilst the links are good and it is nice to do - overhauling the dampers either front or rear to me at least is a no brainer because the replacement & refurbished dampers are so cheap. If refurbished dampers were not available that would be a different matter.

The dampers obviously need attention but not sure if their condition will give you any indication of the function of the springs,the sure way to test for sagging springs is to examine the relationship between the rear shackle and the chassis rail,as the spring sags it lengthens and the rear shackle gets closer and closer to the chassis rail.It eventually starts to make contact,and can be heard as a clonk over bumps,In a good spring the side plates of the shackle should be virtually straight up and down with a slight inclination to the rear.If you look at the rear of the rail you will see if there is any slight contact patch ,a sure sign of new springs required before the dreaded clonk
good luck

checking dampers is always a good start call

Without bothering ESM , does anyone know what " refurbished" applies to exactly...hopefully not just a coat of paint as elsewhere ?
Thanks

Is it advisable to replace the link arms whilst the dampers are off - and does anyone know the longevity of the new link arms?

Replace the damper link top chassis bushes with poly bushes.

A self locking nut will suffice in replacing the castellated nut as trying to find the split pin hole is a problem.

OK - replace the bushes, but what about the link? Or just re-use if it looks OK?

If the ball end rubber looks to be alright just reuse the link.
