What Jack?

I have a 98 TJ with 33" tires and no lift as far as I can tell. The stock jack is missing and I need/want a portable and or a shop jack.

Should I go for a high lift? If so how big?

If I ever lift the jeep it won't be for a few years and probably not more than a few inches.

Recommendations?

Thanks!

48 inch Hi Lift Jack. That's all you need

Personally, I would just find a used factory jack. Or, first, check under your passenger seat to make sure it's not there still. The factory jack works fine up to 35" tires and in a pinch, even 37" tires. I am no fan of the Hi-Lift which I consider to be an unstable dangerous tool of last resort.

stock jack is a bottle type on the TJ's. Also for trail runs get a small section of wood plank to place under the jack in case you have to change the tire in the mud.

My stock Jack would work on my TJ. And my hi lift is more stable than my factory one ever was.

How do you figure a 4' tall jack held into a base with a single pin is more stable than a jack that is perhaps 12-15" tall? And that's a first, reading where anyone considers a Hi-Lift more stable than the factory jack.

How many inches of lift do I need? My floor to frame is 16" so I think I'll need at least 18".

You don't jack it up from the frame to change a tire, you jack it up from the axle. Jacking it up from the frame means you need an extra 10-12" of height on top of the frame height to get the tire in the air due to how the axle droops as you raise the frame. Which is one of the problems that develops from when a Hi-Lift jack is used unless you also chain or strap the axle to the frame so it can't droop as you jack it up from the tub.

Well I'm weird like that. And I use a wide base on mine. 2ft by 2ft.

My immediate project is to get at the diffs, but then I only need a few inches of sag if I'm thinking about this the right way.

Maybe, but I can't figure out what you meant by any of that.

The top bolts of the rear diff look pretty hard to get at and I figure jacking the jeep up would make that easier. Or am I right out of 'er?

Yep, jacking the Jeep up via the rear frame cross member (or gas tank skidplate if it's heavy-duty enough) is the way to get to the entire rear diff cover, track bar, etc.. A floor jack is really best for that job, I stick a short piece of 4x4 on top of the floor jack for extra height.

If your just needing a jack for a flat tire change go with the standard bottle jack.There is plenty out there that will work fine.I wouldnt use the high lift just for that reason,they have there purpose elsewheres

I use the stock jack (with a piece of 1 3/8" X 12" square piece of solid pine for soft sand usage) for on trail tire changes. That base can also be used with the Hi Lift for getting off something or putting rocks etc. under the tires if necessary. As far as a lift goes, a total of 4" is usually considered ideal for 33" tires to avoid problems with rubbing.

Yeah well my stock Jack does not work.
And I've used my Hi Lift for many purposes

This!!!!!

There's a reason auto manufacturers went away from bumper jacks. (which is a "hi lift").

So is the correct procedure to get to the rear diff cover to block the front wheels, jack the Jeep up by the rear frame crossmember, and use a pair of jackstands under the frame to support the jeep?

A High Lift is way too unstable for changing a tire, or worse yet, crawling under it.
Bottle jacks are cheap - just put it under the axle.

Hi-lifts are handy for getting unstuck "sometimes" - but again, they are unstable. Even with a winch sometimes you have to lift it before pulling.

4 feet up on a Hi-Lift - scary!

I carry both, plus a square of 1/4" steel about 8" x 8" - it won't splinter and it stores most anywhere.

Unless I use a ratchet strap to strap up my axle, it droops too much to use my HiLift to change a tire. Buying the HiLift was the worst Jeep purchase for me to date. It lives in my garage now, collecting dust. A good bottle jack works for 99% of what you'd need it for, and takes up WAY less room than a HiLift.

I know, I know.....some people are going to say "HiLifts have their uses." Yes, maybe they have their LIMITED uses, and mine is used as a hat rack in my garage.

I bought a floor jack for the current app. I will need a bottle jack for under the seat. Has anyone bought an after market to fill this void, or should I keep hunting around for a used stock one?
