Sounds like its done some miles then but I presume the wishbone bushes, trunnions and shocks are all ok? However for peace of mind you could take off the hubs to inspect and regrease wheel bearings plus remove backplates. This would then allow the trunnions to be unscrewed for an inspection of the vertical link threads that are can be prone to corrosion and failure. The only sticking point might be that the trunnion bush bolts can rust in their sleeves and so need cutting out which isnt a fun job.
Saying that I wonder if with everything else dismantled (top ball joints, track rods, shock, brake calipers, hubs and back plate off) you couldnt just unscrew the vertical link from the trunnion without touching their bush bolts - perhaps someone on here has done it like that?
