On this truck, I had the dealer remove it before I even saw the truck. But, on a new '04 Superdude, I peeled it off the first 1/2 hour I had it home. Others, I had the dealer remove them.
You can take a hairdryer or heat gun, gently now, and warm the sticker up, and peel it of. Or, a body shop can do it for a few bucks, and use a wheel made to remove graphics and other vinyl stickers.
On my 150, it had a godawful ghost flame graphic from the front wheel wells, all the way to the back of the cab. I didn't know that was on it until my dealer took delivery off it, from another dealer. They removed it with the wheel, and buffed it. Thank God, you'd never know it had been on there now.
I also removed the "EDGE" sticker on my Ranger using the heat gun method, and it turned out well.
If your 4times4 sticker has been there for awhile, I'd suggest taking it and having the wheel thing done. Maybe run a few bucks, but the results would be worth it, especially if you hate stickers as much as myself. I just feel they detract from a nice vehicle, terribly ricerish.
Why do all the manufacturers have to put that on anyway?
On the heat gun method, be careful, use just enough heat to get a corner raised, back off a little, and then slowly pull at a shallow angle. There are plastic trim removal tools that help do this. They're like a plastic spatula, and you get a set of them from Harbor Freight, if not other places, pretty inexpensive.
