Guidance Replacing Trek 4300 fork

[jboz24]

Sadly, the current fork is slightly askew and needs to be replaced. I've never done this before so I'd like to start with some guidance on selecting a replacement fork (e.g. sizing, pitfalls, etc).

As mentioned, the bike was a Trek 4300 mountain bike with a 21" or 21.5" frame...

Any help would be most appreciated. Thanks!
