I've searched the forums, have the manual, and the instructions below. I know they are reverse threads. The first axle bolt backed away, but the larger one just won't budge. Any suggestions? I've heated it, WD-40'd it, muscled it, but nothing seems to be working. Please help!


remove both rear wheels

take off the right rear hub

loosen the chain and take off the rear sprocket....leave the 4 retaining bolts loose

take the caliper off the disk...tie them up out of the way

loosen the axle nuts...remember that they are reverse threads...

remove the clip and then take the axle nuts off...then the collar

remove the brake hub

remove the circlip, then the brake stay

drive the axle out from the throttle side to the clutch side

do the same with the bearing carrier...


for pics, just go to any website that has a parts microfiche(an exploded view of the parts) and use that as a guide...most have that area of the 400ex as 2 different diagrams...the swingarm and the rear axle/drivechain
