Control Arm and King pin question

[230slhouston]

Hello everyone,
Started stripping my suspension and have a few questions:
1. On the control arms, do I have to replace the capped ends (Marked A in pic) They look to be in good shape and were well greased. Do these wear out? I can get the rubber seals (Marked B ) from Mercedes and reuse all the parts.
2. Do I need to change the king pins? i did check them while on the car before stripping. There was no play side to side but very slight up and down - very little. The spacer may have some wear. If I do, will the febi brand be ok, they are not too expensive but will need to be reamed.

I am also not powder coating. I decided to use Epoxy from Eastwood satin black. Any thoughts or comments on this decision?

Thanks for all the expertise.

Maistran.

Hi Maistran,

I have just done this work myself as an amateur.
1. The control arm pivots on the internal thread of the capped ends. As long as there is no play in the movement I would think you could re-use the capped ends. I would change the rubber seals as you have planned and maybe the greasing nipples whilst you are doing the job (also available from Febi)
2. There is supposed to be some play up and down so you may be OK. I will let an expert answer that one. Doing this job will be made difficult by the fact that you have to break apart the assembly to get to the washer.  Febi is considered a good brand. I used them.

Hope this helps

Peter

Not a bad choice, I'm sure.  I often use chassis black from that same manufacturer, or alternate other vendor's products on chassis and engine bay parts that are black. I strive for a crisp, semi-matte black coat, that enhances details.
