You can read an article on Brain surgery, but will you tryit ????

My point is--if your getting under 4000lbs of vehicle, you should have someone there that is familiar with the situation-

We all take chances, some more than others, I just don't wanna suggest something and have a different "situation" showup right in the middle--that can change all parameters-

Years ago I had a 72 "cuda" and was finishing the install of a 426/A727 auto and I had the car on two jackstands/w a tire under the frame--JUST IN CASE--
We had one of our unscheduled earthquakes and the cuda rocked back and forth on the jackstands--evidentally, it didn't fall off !!

Jackstands all have a proper way of use and a dangerous way -

JIMBOX It's never simple-, It will depend on the job-in-hand, if you'll need all 4 off the ground and HOW HIGH you'll need them, but

Wouldn't jacking it up while a stand is under another side of the Jeep be a little risky? Seems like the jack stand would lean with the rise of the wheel you're jacking up...
If you lift one up and put a stand underneath the shock mount/w block, you can goto the other side and do the same--it won't slide anywhere or lean, because of the block and even though you'll be twisting the jeep--it's designed for that---same thing happens when you drop one front tire off a rock, or in a rut--

Like I said it'll all depend on how high you want the jeep, it's pretty common to support the jeep on 4 jacks, but usually for that purpose the jacks are under the frame, so the axles are free to raise/lower for lift/coil chg/UCA/LCA work--my last lift job was with the HF 12 ton jacks/on frame-

If you've NEVER DONE ANY OF THIS--get help, it can be DANGEROUS-

I usually use either my electric jack (12vdc) or my HiLift, to rotate my tires/spare, but it's not something I'd advise--

Yes, I couldn't agree more. I use two methods of supporting it while it is in the air.

I also use wood to protect the metal parts...great suggestion on the jacking point using wood.

As far as soft asphalt, mine is aged and rock hard now. Had I seen any sinking over the summer, I would have jacked it back up and placed plywood under the stands. I think most new asphalt acts that way until several summers have passed and it has had a chance to really compact. Then not so bad. I can't wait until I have a huge garage with concrete under me to work on the jeep in. My wife is pushing me to get this done. Starting this year we are going to really set our sights on this goal saving a good amount for it.

kbwwolf I think the main issue with the ramps is placement. If your garage is short on depth and you have to drive up on them with the jeep still not quite inside, will it clear on the top as you finish driving in and up the ramp?


That's the question. I'll have to take some measurements and see...Either way, I'll get it done. Just a matter of logistics.

And maybe the jack stands WILL work in my driveway. However, I almost dropped my motorcycle this last summer on a 90-degree day. Went inside for about 30 mins and when I came out the sidestand was pretty well sunk into the asphalt.

If yes, then the ramps will work fine for you. The only draw back is they do take up some real-estate where your creeper may be rolling around.

My YJ was up on supports almost all summer on asphalt and there was no issues with it. The guy that did my driveway must have done an excellent job with the underlayment.

What's the width of the legs at the base of those Sumners? 18"? Hard to tell in the photos.

trennmaschine @kb: The jack and stands I got max at 21". If you use Jimbo's suggestion of hte 4x4, that gives you 25" total... I would think that would be high enough for you work on the Jeep. I'm as skeptical as you are (I think),so if I wanted the Jeep any higher in the air than a couple of feet, I'm looking for a lift.

@O_M_Jeep: Those Sumner stands look really sweet!
10-22-2011 11:00 AM
jk'n Wow, good discussion here.

@ OMJ,

Those look sweet. I like how they support with a wide base and like the v top.

@ Jimbo

I haven't used the high lift in the driveway but wouldn't hesitate to use it on the jeep on the trail. It does see lots of use pulling fence posts when I combine it with a chain wrapped around the post and set over the jack.

@ wolf,

Using the floor jack, I jack the differential and lift one end at a time. Since I'm lifting the axles, it is the axles that get supported. On my YJ '92 which is the one that I have had up in the air to do a clutch replacement on it, on the front I had it up on ramps and put jack stands under the axles.

I figure, with me rolling around under the jeep with a creeper I can never be too careful so I use double protection.

If I were working on the suspension and had to jack the frame, I would support under the frame, probably in more than one place.

You're right, OM. The tallest jack stands I've seen go up to about 18-20". Three feet would be nice, but it seems to me that the increased height would introduce a greater level of instability, even with a wider base.

I'm not concerned with the lift itself so much...even a fairly cheap 3-ton lift will get my Jeep off the ground enough to brace it with stands, blocks of wood, etc.

As I said in an earlier post, though, I'm probably overthinking it.

I have a tendency to do that.
10-22-2011 10:44 AM
O_M_Jeep You just cant beat a hi-lift jack for a lifted vehicle, and a 60" is better, I have 4.5" of lift and am getting to the end of my 48" hi-lift way too often, as far as jack stands, go to the nearest welding supply store, I use V-Head pipe stands, each is rated for 3500 lbs, and they come in a variety or configuration from folding legs to multiple heights, I use the shorter 21" I think they are, and they adjust up to 36", that may not sound like much, most jack stands go to about 18" I believe, mine were about $80 ea. but you can find them cheaper online, Sumner is the brand I have but there are several brands.



Not a Jeep pic, but you can see how tall they are at the lowest setting

I weigh 250 lbs and since my daughter was going to be under the car the wife asked me if it was safe, I tried as hard as I could to knock that car off the stands, and I put everything I had in to it and it never budged, I jumped on it, I ran and hit it from the side, after a few half-hearted attempts that yielded no movement at all I got to seriously trying to knock it off there and never could, I ended up impressed again. The best thing is of course each stand is rated for more than my Jeep weighs lol.

I've actually used a HiLift a # of times on construction sites to align forms that were outta whack before a concrete pour.

Never used jack stands, though. Don't know where to put 'em, what size or weight rating to get, etc. And online searches yield a ton of conflicting info. For example, some people think it's perfectly fine to work under a vehicle with four jack stands...others say they would never do it.

Doesn't make it any easier that I have an inherently skeptical nature.

Once you get the Jeep lifted, how do you support it? Jack stands don't seem all that safe to me (easy to tip), especially when you've got to apply a lot of torque to something.

Because of the winters here, and the fact that my driveway is asphalt, I'll be doing any work that requires a lift and/or jack stands in my garage. So I've got a flat, concrete surface.

Once I get my lift installed, I'll need to periodically check the torque on the bolts...I'm assuming that means I'll jack up one end, set the jack stands, adjust bolts, then do the same for the other end.

Correct?

Or is there a way to get the whole vehicle off the ground at once? The thought of using four jack stands, even if they are much wider at the base than the norm, seems unsafe.

Or am I just overthinking it?

Makes sense. Not really sure I would trust jack stands...they seem too easy to tip.

Guess I need to do some more digging.

jk'n I just picked up a 2-1/2 ton low profile floor jack from Harbor Freight for $80.00. I've been very happy with it. It will get lots of use in my driveway. I didn't need uber, just functional. The first use I really needed if for is to lift a tranny and transfer case up high enough under my YJ to be able to set it on blocks and then continue the lift with the tranny floor jack. Jacking the jeep up and down just became a lot easier than using a bottle jack or the scissors that came with it.

Automotive zip ties? Just a thought.
