When changing a wheel recently on my '64 C10 I noticed that the front suspension upper arm is worn at the pivot (front edge) and can be moved by hand with the truck jacked up.
I don't have space to strip it and then wait for parts (from US to England!) but I guess I'll need a new 'control arm shaft and bushing' (eg Chevy Duty # 74-311) but I can't really tell whether the bush has gone or the mounting point has worn away. The truck has hard a hard life with minimal maintenance before I got it.
I'd appreciate any advice on:
* The likely cause of the problem (is it common?)
* How to remove/refit the suspension arm & bushes
I don't have a workshop manual so any advice at all will be appreciated.
Many thanks
Simon
