Jacking points?
 
So guys my jack is not long enough to reach the subframe the "low profile " jacks body will hit my bumper when I lower after I install my coils so my question is can I lift it right next to the pinch weld then put the jack stand next to it ? Or to make my life even easier can I just jack on side right in the middle of the pinch weld and do both sides ?

Get some ramps, or make ramps out of wood. Drive the front onto the ramps for the extra height you need to fit the jack underneath.

lukes Frs 02-15-2016 10:37 AM

Yea don't Jack the car up from the pinch welds they are really not designed to hold the weight of the car. Drive up on ramps an the go off the k members

It's fine to lift by the pinch welds. It's what they're there for.

Depends on what you are trying to do. You can use two jacks and lift one end of the car together, or you can even use a single jack and lift one side of the car as the chassis is quite stiff.

If you are doing this for purposes of lifting the car and working on the suspension, you'll find it best to lift one axle at a time. The sway bar will preload the suspension and make things difficult if one side is lifted and not the other.

Contrary to what you believe, the pinch weld areas are actual lift points for the car and can easily support the weight of the car.

Yeah my concern is that when I lower the car after suspension is installed the jack is not gonna make out its gonna get stuck because of deep in the subframe is :( my idea was to lift from the middle of the pinch weld of one side jack the whole side up put the jack stands then go to the other side

Look it up the pinch welds are nothing more than the visible area that the inerr structure weldsto the putter panel but have fun believing common miss beliefs in factors about you that knows for a fact that a pinch weld is for lifting a car look it up a pinch weld is only designed to support the load of the car when itis in pinch weld clamps on a frame machine. Justbecuse you work at advance auto or oriellys auto dosent mean your a car tech lol

omfg5041 02-15-2016 04:30 PM

Dude, become a mechanic and then tell us that the pinch welds are not for lifting. You can lift any unibody frame by the pinch welds without doing damage to the vehicle. Granted, if they are soft and rusted, then no, don't do that. Since I don't have time to argue with stupid, it might help to look at the following forum link - http://www.ft86club.com/forums/showthread.php?t=10111

Floor jack will probably bend the pinch welds and the article says for factory scissor jack. My concern would be being so low I can't change a tire

omfg5041 02-15-2016 05:10 PM

Using a floor jack should not bend pinch welds. At the shop, all we lift by is pinch welds. at home, I lift by pinch welds without issue. It's a structural point of the body meant to support the weight. If you're really concerned, get a 1$ hockey puck, and set it on the floor jack. Problem solved. Same surface contact area, no risk of damaging paint.

I would suggest you read the Owner's Manual on where the lift points are on the car.

And no, I am not a car tech nor do I work at Advance Auto or O'Reilly's.

And no, I am not the grammar police.

omfg5041 02-15-2016 09:28 PM

It's a rubber pad to provide paint protection or some flexibility if you decide to lift something besides the car (example : lifting the engine - which you want to make sure you do it right if you decide to do that)

You technically can lift by the pinch welds but they do not hold weight well and can be bent and damaged easily. They are the most fragile pinch welds I have seen on any car.

If you land the car on jack stands, be sure the weight is distributed evenly on both sides or else the welds will bend or damage with the weight sagging all on one side.

My observations is that these pinch welds are three sheets of cheap metal pressed together to form the rocker area. It's a horrible design. I have seen cheap Hondas with better pinch welds than that.

As most mentioned..jack the car on the mentioned jack points...look it up on the DIY section some where. If car is too low to clear your jack, roll it on thicker blocks of wood or ramps to give clearance.

Good luck.

omfg5041 02-15-2016 09:56 PM

I love how people with not education in the Automotive field are telling someone thats been in the trade for 4 years now, that he's wrong. Its one of the first things that you learn as a tech. I didn't know that everyone here thats been saying not to lift by the pinch welds were those that built the vehicle and are saying the printed documentation is wrong.

Yes you can. It will work 100%
Will it damage the car? No, but you'll bend the pinch welds. 100% just cosmitic damage.
Is it ideal? Not really.
You'll be better off cutting some 2x4s to drive on. Then lift from the front/rear jack points.

And to the pinch weld scardy cats, don't be a *****.

bleox 02-16-2016 03:11 AM

I know I'm supposed to jack from the subframe and diff but the issues was that ones the coils where installed the jack was gonna hit the bumper! But I just went to a shop

Jacking from the pinch welds is normal for most cars, I jack all my cars from them and have never had a problem.

I had the same issue when I lowered my car. My standard 3 ton jack was not low enough to get under the front bumper to the jacking point. For an immediate solution, I cut some 2x8 to about 24" long and just drove the front wheels onto them, and the jack slid under.

For a longer term solution, harbor freight sells a 2 ton long reach jack for $140, even less when its on sale:
http://www.harborfreight.com/2-ton-l...ump-60678.html

Its low enough to get under most lowered cars. The jack is heavy, but if you're like me and only leave it in your garage, weight isn't a factor. Its also got a very high lift, which is nice for doing transmissions.

If anyone dont want to cut the wood board, use phone book or thick college text book. I know it may sound so cheap, but it works every time and it is free and easy to store (just throw it to the corner lol)

I have jacked up this car by the pinch welds and they FOLD OVER immediately.
They CANNOT support the weight of the car unless you have the "puck" device that supports on either side of the pinch.


Drive the car up on a 2X4 and then use the low profile jack to jack on the jack points identified in the manual.


I can almost guarantee that ALL of the people above that said that it is OK to jack by the pinch welds have not done it on this car

Now do an experiment:
Let the car down off the LIFT.


Jack it up by one corner with a FLOOR JACK
and watch the pinch weld fold over like a limp ....

Dude. I had to lift each individual corner of the car to get the hoist arms under it 😂 fuck you're dumb.
No - the hoist doesn't sit low enough for the arms to swim under it without lifting

I must be SOO dumb that I folded over two of my pinch welds before deciding I should not do that anymore.


I guess the gravity in my area is stronger than yours.


I would go video it doing it again but I don't want to fuckup another one just to prove a point.

No really, the pinch welds are surprisingly weak. Lots of people have already spoken up claiming bent ones and I can do the same. I've never seen one looking to fold over so easily. They respond horribly to being lifted without the surrounding support that the emergency jack in the trunk has. That's why that piece of crap can do anything, really think about it for a second and pull it out and look at it if you don't understand.

To reiterate, the surrounding support such as the flyin miata adaptor, welded fitted tops or slotted hockey pucks are what prevent your pinch welds from bending. They cannot take rotational stress. There are enough people here with bent ones to pay attention. Do not jack the vehicle up from the pinch welds without the aforementioned supports. Use the standard front and back points.

driftartist 02-16-2016 05:46 PM

if it helps. i did my shocks and springs two weeks ago. jacked the car on the pinch welds and left the jack stands on the pinch welds and they are still perfect like the day i bought the car. but that is just me. maybe its the positioning, speed or something at which you are jacking? idk man but i hope it helps. take it easy guys.

mav1178 02-16-2016 05:47 PM

The funny thing is, every (Japanese) car I've owned since the mid-90s have all had the same "weak" pinch weld that folds over easily.

You can use it to jack up the car without issue, other than it bending.

And unless you want your car to be in pristine condition, it really doesn't matter if it is bent or not.

The art of jacking.

Sounds kinky...

Mr.ac 02-16-2016 10:37 PM

Oh no my pinch weld folded over. My car is totaled.

LOL so what? A pair of pliers fixed it. And I still put a jack stand on the same spot where it folded over. And guess what? Nothing happened.

Don't be afraid of a pinch weld. Pinch it back.

BlueSky 02-17-2016 04:38 PM

To pinch weld, or not to pinch weld....that is the question...... ;)

lukes Frs 02-19-2016 12:40 AM

wow what a surprise im not the only one saying that it will bend the pinch welds.

Ultramaroon 02-19-2016 02:03 AM

Why put up with deforming your car? I cut up hockey pucks.
