It's almost like it is unaligned, like the trucks are crooked.
What should I do to check what's wrong?
Can this problem be fixed? I really like this board and kit I don't want to have to buy a new one.
Get some bones medium hard core bushings. These have better rebound.
First thought that comes to mind is that your bearings are compromised. If you've had this skateboard for awhile or ride it a lot, all of that weight can wear down the bearings and make it roll "off". Secondly, the wheels could be worn (coned). That is where the outer edge of the wheel has worn more than the inner edge. Not as noticeable when you are on the board, but really noticeable when you roll it with you not on it. Thirdly, bent axle on the trucks. This too could just be from regular usage. If you really like the deck. Start with the bearings, wheels, trucks...Shouldn't be a problem with the deck itself.
I have a Nickel myself, I recommend either tightening the trucks or getting new ones
Inspect the integrity of the wheels. Tighten your trucks to be stiff, and see if it wobbles.
I would guess your wheels are warped.
Cheers.
maybe your trucks should be tighteen
maybe the trucks are crooked...
Are you capable of using a spanner...?
