I replaced both strut mounts in my 190E without even removing the front wheels. Leaving the tyres in contact with the ground avoided the need for any other restraint or support to prevent the spring releasing. Most time consuming part of the job was coming up with a 7mm allen key to prevent the strut piston rod turning. Otherwise the job was took as little time as suggested in the first post.

See post #17 on page 2 of this thread: Strut mount wear - how to test?
