| Using bottle jack on Air equipped D3s |
|
An interesting comment from one of the service guys whilst waiting for my brake/pump recall work to be completed. I mentioned that I trusted the provided scissor jack about as much as I trusted a ex-lax fed puppy on a new carpet, and that I kept a bottle jack for jacking the wishbones.
There was a general agreement over the suitability of the provided jack, however he noted that he thought that the air sprung cars had a different lower joint than the coilers, that was only made of lightweight plastic and only designed to carry the weight of the wheel when raised off the ground, rather than the entire weight of (1/4) of the car when jacking underneath it. He believed that the coilers had a reinforced part to cope with the extra stress.
Has he been misled, or is there some truth that lower wishbone joint damage may occur from jacking a non-coiler in this way?
Any advice, or a traditional D3 forum slide into off-topic gratefully received  Dr. Ian Malcolm:

Transgenic tomato anyone?

Personally I think he's talking  ....
There would still be the same weight at that point, but it would just be suspension by air instead of spring. But it's still the same weight.... (maybe you shoudl fill teh air suspension up with Helium? Would that help....? Bodsys Brake Bible

I was wondering that Bodsy...except...in my deluded and definitely overstressed head I could see the bulk of the weight of the car normally being directed through the top ball joint, not the lower one. The lower one would be subject to lots of lateral forces, but I could only see it's vertical loading coming into play when the wheel is hanging freely. I reserve the right for my brain to be telling me too; it wouldn't be the first time 
Helium would definitely be more fun if the car vented the excess into the cabin space though, maybe it'd help the voice recognition?  Dr. Ian Malcolm:

If Al is providing it, it might be a bit small. You might need something bigger! How come you need Al to sort something surely they come with something to bung up your rear? D3 HSE MY05 Auto

.......Please tell me this man is talking BILGE  , I'd never want to take a corner at speed again, for fear of the whole bl**dy lot folding in on me, if I thought that was true.

He seemed quite convinced that the only issue was the lifting of that point, not any other loading factors, but it still seems very unlikely that they would produce two different parts when one (stronger) part would do for everything. Dr. Ian Malcolm:

Bungage is still being looked into. I remember now why it took so long to get the first batch sorted. Blimey, don't people want business these days?
Hope to get some news later this week or early next  I know it's not considered "kind" to say no these days, but no. Just no, ok? And if it's not ok, still no.

Thanks ND, I can see it's a long winded up hill struggle to get these things moving; appreciate it Dr. Ian Malcolm:

Used compressor with Bushranger XJack (4 Tonnes). Quick, clean and controllable, good for positioning stands, no poisonous gasses. There's one wheel on my wagon, but i'm still rollin' along, it's the cherokee, they're after me, but I'm singing a happy song
