Front lower ball joint cover replacement

[Alan_M]

I’ve read through the how to’s, but have a couple of questions

Is a 18mm flexi head spanner essential. I have just about every other type of spanner and socket, including crows feet sockets, but not a flexi head ratchet spanner.

Will I need to have wheels realigned? I’ve only just bought it, so may well get alignment checked anyway.

Thanks
