Prepare the bumpstops on the Cherokee by sanding them down. Trim the upper bumpstop and use a rubber mallet to hammer the provided bumpstop cover onto the bumpstop mount. Meanwhile, trim, drill and tap a hole into the bumpstop on the axle. Secure the spacers and new bumpstop to the axle assembly. Reattach the axle to the chassis, install the coils and connect the upper and lower arms to the axle.
