Who has built an adapter for a floor jack to make it easier to lift the whole truck from the center of the axle?

With the offset diff I typically lift one side of the truck, put a jackstand under it, then lift and jackstand the other. I'm going to build an adapter that will allow me to put jack from the center instead but I don't want to reinvent the wheel if it has been done.

Thoughts?

excessive much?

I don't like lifting the whole axle at once. I get sketched out
just lift it one side at a time under the spring perches.
if you have to have the whole front or rear up. use jackstands i guess

Safety first! :cheers:
 
The idea is reasonable, but their design is sketchy to say the least, unless they're using 3"x3"-1/4" wall angle iron to bear the load. Also, instead of the bracket sitting on the jack pad, it should replace the jack pad. It should have a stud to fit into the swivel base under the jackpad.

You can lift it buy the diff. The whole truck (front or back) will lift up. There's nothing sketchy about it. I'm assuming you're not crawling under there without jackstatnds, anyways.

Maybe on a 40 (i know this is the 40 forum) but I have a 60 too and while I CAN lift it with just the diff it gets really tippy. I'd like a "better" solution.

Since it is just for the lift and not the support I think the adapter doesn't need to be SO strong as I would want it to be for a support.

I agree that using the jack's post hole would be a good feature.

I would NEVER go under with just a floor jack, never.
 
I jack the hole front or rear up by putting it near the pumpkin with no real problems. Noting sketchy about lifting the hole front up with the rear two wheels on the ground. Your idea makes sense but how often do you need to jack it up to make that worth while.
 
actually, i have been pondering the making of a adapter for a couple decades. i get the idea and then the need passes.
do you really need one, sure, why not?
would i recommend using one and crawl under, not a chance. to check diff play, axle rotation then yah or even the ability to put both jack stands under at once makes it usefull.

but

i would want it extremely strong with a centering pin that goes through the jack. maybe i will go ahead and build one ... maybe not.

subscribed to see your results.

I'm thinkin' if you would have just built the thing you could have told US how well your new cool homemade tool works in the time it took for this thread to run it's course. ;)

Just sayin'...

Don't go all "practical" on me now Nick... ;)
 
Mark:

IMO you're over-complicating this. I lifted my FJ62 many times by putting a chunk of 4x4 on the jack saddle, I do it all the time now with my pickup. I always get the stands ready first, set them right next to where they are going to support. Jack it up, slide the stands under, lower the jack.
 
But there are times when all I want to do is jack one end up with the jack, say to change tires (I swap ATs for Swampers when I wheel) or to just check the bearings for example. I wouldn't use jack stands for that and I am careful to not put any part of me under the tire/axle during the process. Currently I do one corner at a time but it would be easier and faster to not have to reposition the jack to each corner.

This is not a NEED as much as something, if easy enough to build, would make life easier.
 
I considered burning some metal for the same purpose as I was swapping tires at camp for a few years but replaced the swampers for MTR Kevlars. I like the idea and application and would have made life a lot easier. Fire up your welder and build it a little stronger than the patent illustrations and post your works.
 
I've been considering fabbing something up myself. Problem is I'd need to use some pretty thick stock I'm thinking, and I have no real good way to cut it. Be nice to have an easy way to lift up one end of the truck in one shot, keeping it level so I can easily get jack stands under the spring perches.
 
For the kinds of things you are describing, how about two floor jacks - one under each spring pad? Fast, stable, no mods required.

Sure, but once it's up I still need to get jack stands under there. No way am I going to work under my truck while it's supported only by hydraulic pressure. That's just asking for trouble.
 
umm, just to play devils advocate, lifts are hydraulic ...
for me it isn't so much the hydraulic jack that makes me not work under a vehicle supported by them, it is more the instability of them. jack stands save lives and limbs.
