Most likely; that'd be a real cockup if they were referring to the dustcovers for unsealed bearings as seals.

Sweet, you got an F4, that's awesome! I have an F3 2004 Haro, so you must have gotten the new line (2005) right?

No, they are referring to dust covers. Odds are good that the bearings are in a bearing race and there is a cover over the bearings that is held in place by your crank bolts that uses pressure to keep dirt and crap out of the bearings.
It's a relatively cheap way to do things, but works alright. I am surprised they have that instead of sealed bearings though.

The new f4 have the same cranks as the backtrail x3 and the mirra 540. They are sealed. I aint full of it eather. The f 3 uses unsealed. My friend knows his haro's also to e-mail him ray_almighty@hotmail.com. Also check the web and look at them.

The x3 is sealed mechanism also. The Mirra 540 uses a different crank. Check Haro's website for details.
