Tongue hits arm of spare mount. I've put some tape on it to keep it from rubbing, but doesn't seem like the right solution. BIOR rear.

Make sure jack is all the way in the "down" position. Mine fits with a close tolerance. Tongue definately faces the tire (not the light).

Is anyone else with a BIOR having this problem too? Any chance the hi-lift extreme sticks out farther than other models?

Good question. I have the standard model with no issues. I have a neoprene cover, which does touch the tire carrier, but the jack does not.

Mine touches. I just threw a piece of rubber hose slit down one side over the tube, jaw sits against it. I also have the X-treme jack, there is no difference in size or shape between the x-treme, cast, cast & stamped.

If you don't want it to touch, drill a hole in the base and then mount a bolt through the base that the hi-lift base can slide on to. This will also prevent the base from sliding out the other way (away from the tube). The top of my jack just very tightly against my 315 spare. So much that i have to run a 10mm spacer just to fit the jack.
 
Good ideas Layonnn, thanks!


Btw, what's the best/easiest way to lock it?
 
Mine touches. Also, make sure to secure the secure the jack. Mine pivoted upwards and smashed my tail light when I opened swing out.
 
This is what i did. I was afraid that the tongue of the hi-lift would hit, but it actually doesn't.

I have the 60" cast hi-lift
 
Wow. How can there be so much difference in clearance with the same arm?
 
If you compare my pic to yours, my hi-lift base is placed more toward the spindle of the arm. I bet that if we lined up the holes on each of our jacks, it'll be that i probably placed the bolt one hole higher than yours. Try it and see. My guess is that if you move the jack base, and place the bolt through, it'll be at a different hole than it is now. My jack doesn't move at all. It's pretty secure.

Also, i was reading your OP... take a look at the lock that i have on mine. It works. It's not the toughest security lock out there, but it does work. It's a masterlock spare tire lock.

I would note one other big difference.... Look at how the two are secured. 3d FJ has a bent metal plate that the washer and then wing nut secure the jack with. The OP has what looks like two washers and a wing nut. He doesnt have the bent metal plate between the washer/wing nut and jack. On my BOIR, I have this same bent metal plate and found it to be directional... depending on how I install it, my High lift will or will not hit the arm once tightened down.

Once I figured that out, I have never had an issue. But, I agree with others, the simple fix is to just drill a hole in the base and put a bolt there that lines up with the holes on the jack base... or weld a little stud.

It is because of the way that the jack is held in place.

The jack is not held in place by the upper mount and the base. The jack could then rotate around the upper mount and it would not stay in the base. I found this out because i mounted my jack before i had my spare mounted.

The hi-lift is held in place by the mount pressing the jack against the tire. This creates three points to stabilize it. If its not touching your tire (due to either having narrow tires, different rims with less backspacing, etc.) then its not going to be very secure. You need something retaining it to the base, like a bolt sticking up out of the base, to keep it in. (same as what Mxndrnks said above)

I wish it would come with some kind of pin that sticks up out of the base, but folks run various models of "farm jacks" that may have different bases.

Those complaining about the design, well i have seen first hand someone's hi-lift pop out of the base of their Slee rear bumper hi-lift mount and smack their tailgate causing a good bit of damage. So, no bumper/swingout etc is perfect.


Also, what works well to secure it from theft, a gun cable lock works very well. Buy a nice one though. The cheapo ones that comes with most handguns do not hold up well to the weather, mine have all rusted.
