New Jack option.

See my Rover-Tech jack thread for a good alternative.
Kevin says the first D3 flat he changed did exactly what Tombies did,except he had the wheel off and clear.Just had time to shove a wheel under the vehicle as it toppled so not such the drama Tombies was.

Not quite following you on this.

The stress in the chassis rail is not the problem. As the chassis is lifted higher the top of the jack no longer wants to be directly above the bottom of the jack. This is due to the chassis rail being lifted in an arc around the wheel on the other side.

This problem exists for all jacks. The trouble with the Disco is the height to which you have to lift it - the horizontal movement of the chassis and therefore top of the jack becomes significant.

Something has to give. In some cases the bottom of the jack may move. In most cases the jack will start to lean. This puts a sideways load on the jack which it can't really cope with. This is exacerbated if the locating pin on the top of the jack jams in the hole in the chassis rail putting a significant bending load on the arms of the jack.

I see why the angle of the suspension arm looked too great when i tried. I had it at off road height. My final solution is just to keep my bottle jack and carry a couple of hard wood timbers to drive onto at all times(as mentioned by others). Although seeing as I broke my collar bone on Tuesday I'll have to hold off on the next dummy run.

That arm is Certainly not a D3/4

Being part of the general confused can I ask where on the control arms should you jack from on a d4 with air suspension , front and back

Pics would be great as I am also word challenged

Another question

Would it be possible to say jack from the chassis just enough to get another jack under the control arm.

Or perhaps have a very low profile jack to first jack from the control arm enough to fit another hack under the control arm

Sorry if this goes not make sense

And thanks for any help

Richard

Richard, my photo a few posts back is a D4 arm. Front and back are very similar.

And yes a bit of jacking off the chassis can get things high enough to get under the control arm.

Cheers,
Scott
