w210 LCA Tips

[Simpler=Better]

My buddy's w210 lower control arm rusted out and failed in his driveway. No real damage, he got lucky.

Any tips for slapping a new-used on it? Or is it as simple as pull the spring(with the $175 tool), slap the new one in, and uncompress the spring?


I know about the spring perch problem, he had those replaced years ago.
