Hey, first: sorry if there are any mistakes in my post, english is not my native language. ;p second: i have a problem with my SpeedDemons trucks. At first, they were quite tight, but lastly they became looser and looser. I fixed this by tightening the kingpin, but every time i did it, trucks became looser every time i went skateboarding. The problem is, i so hardly tightened the nut that i can no longer grab it with the spanner (i'm not sure if this is a right word, lol). The problem is with both trucks. Also, i have broken both kingpins some time ago, and bought new ones, but i'm not sure if they have the same size as previous kingpins. Maybe this is a problem? Nevertheless, i need to make the nuts come out of my kingpins, is there a way to do it without destroing the nuts? Please, reply!

Maybe you have to tighten the bolts, not the king pin. Could be that, or maybe your bushingsare too soft.

dude man this happened to me on my thunder trucks. after many attempts to fix this. i just went and bought some ventures. best of luck tho

it can't be bolts, but the now i thought that the kingpin might be a problem. i've managed to take off the nuts and want to buy new bushings, maybe it will solve the problem. However, i have one more question to you! Do your kingpins fit perfectly into the holes in trucks? Because mine are a bit thinner. It may be the cause, so i need to know if i have to buy new kingpins or not?
