Cobbled together a hi-lift mount on my BESRK tire carrier out of 3" square tube. Nothing special, just some free scrap left over from my fence project.
A couple 1/2" grade 8 bolts hold the tube to the carrier, and three 1/2" grade 8 pan-head Allan bolts hold the jack to the mount. Why three? Because if I drop/lose one wing nut in the mud I'll have an extra.
The slight angle of the bolts relative to the long axis of the tube keeps one end of the jack base pressed against the mount and rattle free.
You have to start somewhere to get to the middle of nowhere.
i dont understand why people mount it on the outside of the jeep. i mean there is a list of reasons not to. i dont see the purpose other than it does look pretty sweet.
My reason is my dog. When I go camping/light-wheeling, I have a girlfriend, a 30 pound dog (that requires a little moving room in the back), and than everything packed out in my ammo cans, which are mounted and don't move, a cooler for cans of beer....I mean soda, and the sleeping bags, tent, etc. in a military medical "drop" chest:
^$25.00 at the local army supply store. 2-sided (top/bottom) both water-tight, and this thing can be dropped from 100 yards out of a helicopter, so it will probably survive any terrain wheeling in the back of your jeep...
This means I have basically no room after you jam fishing poles, extra boots, waders, vests, tackle boxes, etc. in the back. If I had a family-style cage, I would probably out the hi-lift to the top-back of the cage bars, but with a sport cage, I just end up having to move the damn thing every time I open the tailgate. I strayed from the bumpers as I've seen them get hit/bent up or back there...and I'll probably hook it on my swing-out tire carrier after I get that finished...but for now: that's the best place to for it to always a) be loaded and b) be accessible without being an obstruction.
i like the drop can... I used to have all my gear in metal ammo cans of various sizes, then i saw the light, so to speak. Now i use soft sided bags for gear that allows for use of all available space, since the soft sided bags will cram down into and otherwise fill voids and the end result is more gear can be carries in less space and its much more efficient.
An external high lift is fine if out back and not in direct contact with the elements like in the front. I made up a water proof 'gator' for the moving parts of the jack to keep it all lubed and ready for action. High lift even sells a noeprene boot to cover and protect the vital parts of the jack.
I ordered a neopren booty for the mechanisims so they be safe. if you look closely, the wing nut ont the pass side has a lock through the top of the bolts. so it's safe. when the things get here i'm takin it off and lubbing it and cleaning the rust that has been on it since i bought it last year. EXCITED! haha
