Front lower arms... Am I missing something?

[B4-Andy]

So 1 arm on each side of my S8 needs doing, but I reckon it’s probably just as well to do all 4 while I’m there. The tops are all fine.

My quesiton is... Are they really easy to do? It seriously looks like there’s 2/3 bolts to just pop off and on, then wrestle the arm out and new one in. Is it actually really difficult to do or is it as simple as it looks?

Also any advice on where to buy would be appriciated, struggling to find decent quality ones. Except one guy in Poland who appears to be selling the whole front end.
