The Strong Arm Stabilizer is just a pipe inside a pipe that is 'secured' in place via a locking bolt.........
Now IF you mean the front landing gear on passenger side........
That is a 'slave unit' driven by a cross bar from roadside master unit.
If roadside goes up/down and curbside doesn't move then check for a broken 'shear bolt' (one on each side) on the cross bar.
If both bolts that attach cross bar frm ne side t other are intact.....'
then slave unit could have a broken shear pin inside the unit....remove thin sheet metal top and check inside
