Reminds me of a time someone decided to drop off their aluminum ladder in the middle of the interstate. Ended up with two flat tires!

I've started a new thread devoted to the spare tire mounting:

Are there places where a floor jack could be used? (not including the lift point under the doors). The 2011 service manual shows two spots (front and rear), but I think the manual is wrong.

I'd like to get the whole car off the ground using a floor jack and four jack stands, leaving the wheels free.

Thanks for the great pics!

Yeah, the pics (page GI-42) looks wrong. Certainly, the pic of the rear shows the lift point being near a differential, a drive shaft, and two cat converters and exhaust pipes!

Just curious: why do you need four wheels in the air at the same time?

The service manual shows use of "board-on lift attachments" between the door sill lift points and a "board-on lift". (It's apparently a generic Nissan pic that's also used for, for example, "2009 Nissan-Datsun Altima V6-3.5L (VQ35DE)". I have a similar adapter for my hydraulic jack.

When I need to get both wheels on the same side in the air at the same time (e.g. rotating tires), I jack the car up at the front door sill jack point high enough so both front and rear wheels come off the ground.

When I need to get both wheels at one end in the air at the same time (e.g. when changing the anti-roll bar) I put the jack under the A arm, jack the car up, put the jack stand in at the sill, and repeat for the other side. For stability and safety and longevity of the door sill jack point, I use a home-made "adapter block" between the jack stand's head and the sill:

Thanks for the detailed info Andy. I want to get all four wheels off the ground to make it easier to move around and work under the car, apply undercoating, work on the back of the wheels, brake lines, drive boots, etc. It's not necessary to airborne the whole car by the frame, but it makes some things easier.

There may be a way to get the car off the ground by the wheels (e.g. ramps) but I don't know an inexpensive way to do that for all four wheels at the same time.

This is what I did the other day when rotating my tires. Lift up the front high enough so that the rear just comes off the ground. By then it's high enough to slip a jack stand under the rear seam and lower the front a bit which picks the rear tire off the ground a bit more. Problem is that it doesn't make getting a jack stand under the front seam easy so you have to hold the car with the hydraulic jack which isn't recommended.

Got a better pic of your seam adapter? The one I have could fit a bit better!

I looked briefly under the front a-arms but I didn't see any obvious points that looked beefy enough to support the car. My last 2 cars had easy front/rear lift points for jacking which I took for granted!

Google turns up a few adapters which might help for getting one side of the car up on jack stands easily:

Couple of these: http://flyinmiata.com/?deptid=5673&stocknumber=35-70000
One of these: http://www.summitracing.com/parts/SUM-918008/?rtype=10
Doubt that 34" is long enough, though - probably need at least 55" or so? The Flyin' Miata guys say that their adapter is good enough to left one side of the whole car, but don't know if the LEAF's sills are reinforced enough in the middle to do the same.

"Better pic"? Better how? Everything I've got is in the wiki:

There are diagrams for a "jack block" as well as its Google Sketch-Up schematic.
Let me know if you need something else.

I generally put the jack's head at the inboard end of the A arm, or on the subframe, like this, on my old VW. If there's not a convenient spot, I'd put a length of 2x4 under the A arm spanning the bushings at its inboard end, at the two white arrows' end in the following pic, from http://blogs.insideline.com/roadtests/2 ... round.html:

Yeah, Miatas are like 2600-2800 lbs. The LEAF is at least 3350 lbs. which at least an extra 275-375 lbs per side. I suppose one can lift the car slowly and let it back down quickly if there are creaking or crumbling sound or if the sill starts to buckle :D . I kinda think it'd be OK since the sill is part of the side's perimeter and would need to be strong to resist a big side impact. OTOH, I don't want to be the first to find out that it's a bad idea to jack a LEAF up at the middle of the sill! :D

I wouldn't go with the Miata adapter since the LEAF as a little hump on the inside of the pinch weld at the jack point, which would prevent equal contact with the sill on either of the weld. My jack block accounts for that hump.

Hi aqn,

Will using 2 cheap 1.5 ton rapid floor jacks simultaneously be safe enough to do tire rotations? Harbor Freight sells the 1.5 ton for quite cheap. I already have one, and was thinking of picking up another one of those.

I just never liked using the cheaper standalone jack stands.

that is what i have used for years. not sure of the rating on them but i found it to be a quick and easy job. nowadays, it takes me about 20 minutes but in my younger days i could do it in 12-13 minutes rotating all 4 tires.
