High jack - how to ?

[kis]

So what about all M cars? They've got no structural integrity?

It's like a ceiling joist. You can happily drill a hole through for wiring to run and this doesn't affect the integrity. Of course if you're cutting out strategic points where it would fix to the car then that's different. But if the M can be structurally safe and use the same thing, why can't any other Zed?

Sorry I was not very clear. I mean with the jack pad it fits nicely into the square hole as mine did, but the whole plate got pushed up ie 6 inch square of metal bend up until it hit something. I presume it did hit something as the car started to lift, but it did not feel very stable like it was just bending wider and taking the strain

I meant with no jack pad you will crush the indent edges as you won#t get a flush pressure point

Next time I'll do as you say, pull back the platsic window and look in to see it is flush with the cross member - once I see that - its a no brainer

All in all its still a really shitty situation that something is there, but bends up and why M only has a pad already fitted. Why would that be the case for such a fundamental way to lift a car. I franky just don;y understand it - more so as its a key safety issue ......

There is no cutout for the M afaik, but there must be something behind the indent for it not to crush.

I see, so no cut out but something is sitting there behind the undertray? While all other Zeds have an void? We got anyone with an M that can confirm?

Yeah the indentation is there but there must be a gap of some sort on the non m that is filled on the M, otherwise it wouldn't crush. I remember there being a structural piece behind when I've taken the tray off.

Got it. Hosted up inch by inch, front and back.

Square front indent is indeed strong enough and once bent in a bit even with the puck, sits flush with the cross member. You can see it is slightly deformed, but minimal.

I got big high 6 ton jacks so that they are soild even at 450mm, not at the height limit of cheaper jacks

Seems about high enough as it is and easy to slide my board around and get to most things.

I have a 2 more fail safes, trolley and wishbone ( wedged in with a mallet ), then final dead man saver with bricks

Personally I wouldnt leave the car jacked up over winter. Just make sure you move the car back and forth a few times to ensure the tyres dont flatten in contact with the ground.

This is to do some chores, once they are done, I'll be back down.
