front bump stop removal

I am putting new isolaters all the way around and cannot get the bumpstop off to put the new isolators on, what is the trick to getting them off? I need this done asap to get it back on the road.

you need to take out the rubber bumpstop itself to access the bolt that hold the cup to the bottom of the spring post. ive always had trouble getting the rubber out. if you still have the coil in, ive found it works well to use a pair of channel locks and reach through the coil and grab the rubber bumpstop. then using the coil as a fulcrum, you have leverage to pop it out. then you can access the 15mm
bolt inside.
edit: or you might have luck using a large flat head screwdriver vertical to pry it out

i think some people grind the edge of the cup so they dont have to remove them to clear the isolators or coil spacers.

I used a pipe wrench on the cup that holds the bumpstop to get mine out.

You're going to have to take the coil out anyways. Once it's out you can do as was mentioned above, I've always just used a BFH to get the bumpstop out. Once that's out you can just unbolt the cup. Installation is the reverse. I found that getting the bumpstop back in can be a challenge. The easiest way I found was to compress the axle without the spring until the spring pad contacts the bumpstop to press it back in.
