I installed Demello Rock Sliders last night. They took about 3 weeks to ship after I ordered them, but I'm glad I waited. Here are a couple of install tips:
Tools required:
Two 5-gallon Home Depot paint buckets
ratchet set with both normal and small-sized ratchet
worklight or flashlight
1. Demello shipped 16 sets of one bolt, two washers- perfect. The factory-drilled holes in the FJ frame are already threaded, so the install could not be easier. The Demello bolts were stamped 10.8, which should be very sturdy, especially considering each slider gets 8 bolts.
2. Make sure the threads on the FJ are reasonably clean before starting. I checked each hole by screwing in a bolt several turns, then backing the bolt out. This made it much easier to mount the sliders later.
3. Line up the sliders on the ground. It's obvious after you get started, but there is a Left and a Right slider, determined by the longest space between mounts being in the front. This is the only way the sliders will attach.
4. The sliders were heavy, over 40 pounds each. I found the easiest way to get the job done was to place the sliders on two 5-gallon Home Depot paint buckets, then slide the whole works into position under the FJ. You will need to twist the back of each slider a little in order to slip the mount under the brake line. In a non-lifted FJ, the combination of Home Depot buckets and Demello sliders is perfect. To line up the holes, you'll need to push up on the mounts just a little in order to get the bolts started into the frame. With this method, the slider install is easily a 1-person job.
5. I started with one bolt on the front, one bolt on the back, not fully tightened. This provides more than enough support to be able to wiggle the buckets out and access all of the holes. After all bolts are in, tighten all bolts, then re-tighten all bolts. There is one in the front that will require a small ratchet for best results.
Note about the brake lines:
I did not find it necessary to swap the brake line clips. I've read it's required with some of the other sliders. As-is, the Demello rails make the lines a little more tight, but the lines are not stretched or even slightly kinked, so they should be fine. What does everyone else think?
