How do i change a BMX fork?

Question

i think ik how to fo it but im not sure

Answer 1

loosen the stem bolt about 1/2 inch, then tap it back down with a hammer (or the likes). This will dislodge the wedge holding the stem in place. Remove the  stem (with the connected handlebars). loosen, and remove the top (and rather large) nut from the top of the fork. Remove the washer. Remove the one remaining race/cone nut (large pliers might be necessary) and the forks should slide out of the frame. Don't forget to clean ALL the old grease from the bearings and races/cones (inspect and replace the bearings and races/cones if wear is evident!), regrease and reassemble...reassembly is the reverse order of fork removal.

Good Luck !
