Most of the trick with the Omega is getting the geometry right. The mechanicals are all pretty clear cut.
For your purposes, a pry bar isn't necessary
Jack the front end and support it.
1. turn the steering lock to lock with the engine off.
2. grab the track rods and try to twist.
3. grab the wheels in turn. key out, steering lock engaged and rock side to side (track rod play) and top and bottom (bottom ball joint).
4. grab the tie rod and try to twist.
5. grab the drop links and try to twist.
6. grab the steering idler and box drop arm and try to move up and down.
You're looking to identify any noises or excessive movement... a good ball joint will move by hand but will feel tight. A knackered one will literally rattle as you shake it
If gripping is an issue, use mole grips. Same applies but allow for the extra leverage wrt movement
