There should be a retainer assy viewable from the rear. I usually support the steer axle w/a floor jack & pry the pivot bar out the back using the retainer assy for leverage.

If the bar is broken you'll have to drive it forward towards the engine & cut the end off as it hits the engine front pulley. Time consuming but doable.

There is nothing else holding the axle in place. If the bar is removed & it's still stuck in position- get the ole' pry bar out & work up a sweat!
