Aftermarket Febi-Bilstien control arms are around $170.00 each; balljoints are about $30.00 each on average. I think the 400E shares the same control arms with the 300CE-24. I guess they are welded in too, but I don't know. My driver side front tire is worn badly on the outside edge, and I have re-lubed my ball joints twice already, so it looks like I will have to bite the bullet and work this out.
