Hey guys. My idler arm on the drive belt seems to be quite wobbly in the vertical direction and is throwing belt on occasion. I replaced, reinforced all the hydro/frame mounts and this seems to be the last thing that could be causing the belt throw. I can get to the bushing after removing back tires but how do i replace the square carriage bolt? It seems to be under the engine and can't just slide it out. Any ideas?
