A tool that if something was pushed to far together, it can push it back away.

Pickle fork comes to mind (used on ball joints and tie rod ends)
Porta-Power for body panels.
Your question is very confusing. Need more info. Spread away from what? Push back away from what?

There are seal pullers and bearing pullers and slide hammers and steering wheel pullers and harmonic balancer pullers/installers. And there are ring spreaders that remove and install retaining rings/clips. Also, punches and broken bolt and screw extractors or "easy outs". Good Luck!
It's called a pushway. You can get it at your hardware store, they usually keep them by the sky-hooks & board stretchers.
Pry bar?
