john,
when jacking use a block of wood, stops the scraping the zinc off / wax oil, (i suggest this but i dont do it )
jack at the axel bolts

I thought of that, but I'm a bit nervous about doing anything that might make the car less stable than it already is, jacked up or on axle stands. Still, I suppose that's the sensible solution.

Thanks,


John

even if you scrape big lumps of galv off it should be a while before it rots through 3mm given that its usually pretty dry under a car

I read somewhere that galvanising will protect adjacent uncoated steel from rusting and this does actually seem to work. We've got a galvanised wire grating over a drain which was cut from a much large grill. The cut ends have never rusted in 15 years or more. So I suppose the same will apply under the car.

So I don't really know why I'm concerned. Just a worrywart, I guess.

Ho-hum.

Cheers,

John

when i bother, i use a bit of softish 18mm ply square piece as its soft and moulds a bit to give best grip, someone will tell me im an idiot for using ply but hey ho

Hey ho

Only kidding - ply is actually a good material to use as it doesn't have a single grain direction like solid wood, so shouldn't 'snap' along the grain.

As long as the piece you use is sitting flat against a flattish piece of chassis/suspension mounting, and the jacking plate is also flat and placed directly underneath - so's the ply is in compression only - then all should be well.

Thought I'd let anybody that's interested know that now that I've set the suspension using the method recommended by Sean and set the heights to what Ken recommended, it all seems to be stable now; i.e. the suspension has stopped adjusting itself.

Thanks to all who responded.

John
