On what type of vehicle?
you shift
change out the hub
Need to know if 2 wheel or 4 wheel drive for the front. Either way, there is no nut on the back axles.
itsa stupid ugly!
How do I change a wheel bearing
You will need to change the gearbox, swing arm, back wheel and, probably, brake arrangement and shocks.
Back wheel drive
no
Pull the back wheel off and there will be bolts (probably 6-8) holding the sprocket on to the rear hub. Take the bolts off, change sprockets and your done.
the old ones have to be pressed out and new ones pressed back in.
Explain how the mechanical advantage of a wheel and axle change as the size of the wheel increases?
I unbolted the cover on the wheel well and reached in to change my signal lights. Then I bolted it back on. I hope this works.
