and its great 30 seconds later the cars say 40mm off the floor which is fine for changing pads and disks (rotors?)
I had intended to put axle stands just behind the jack but with a flat floor car where are the cross member IF there are any ............... Where do you put the the only sensible point is where the air jack sits
I have read bits that there is a round bung at the front that so far I have not seen on the center line of the but nothing on the rear. If such exist I can swap the air jack for another that might go that far under the car.
The one I have my son wants if I buy another so I am not bothered about buying another say one of these
Well I thought about using the front suspension arms but they look thin and bright and the rears look tight to get one of my axle stands in. I will have another look.
Think I really need new stands ...... they are a bit tall and date back to 1988 nor a bit old fashioned without a ratchet and they were my second set
I have read some owners put the jack under the differential casing but is that aluminum or cast iron and is curved so not making a very secure point to lift up on
My thought on all this is manufacturers are just allowing for car hoists, that is the safest, and not any owner maintenance or for that matter roadside
Be safe! Lifting and supporting disasters happen with painful to fatal results.
That is so correct John before I retired I designed and supervised large building services and mistakes happen so do injury's from lack of thought
On one delivery of a 33ton boiler on roller skate skids one of the controlling steel rope mounts failed and the boiler moved very very slowly across the slightly sloping floor at say 2MPH. One very fit looking large helpful soul decided to help and rushed across to manual stop it until I lead him away pointing out he would just he a red splash on the wall....when it hit the wall 3-5 minutes later it crushed the boiler casing and wall render. I should say that was so unusual and a one off nothing normally goes wrong but the point being you can never say it will not. The wall and boiler were fixed in a few days
However I seem to have answered my own question for the front single center jacking point
See images below
So that's the location and the clearance below with the suspension raised is 170mm or for you on the other side of the pond a tad over 6.5 inches
From one of those cheap manuals on line it is Part Number
33100 Stop plug under front axle carrier /vehicle jack support point
Sorry about the quality its just a picture of my monitor image
I cannot find similar on the rear in that manual so I guess its the diff or suspension points
As to that air jack by Selson it does make a good support but would I trust it to do more than remove a wheel........NO but tyre shops use them and man in a van tyre changer did here last month , when I first saw one, all the time so I am overly cautious
No apology for the dirty car as there a hose ban on here
But I will need the one they sell that's more like a trolley jack

Reason: miss-type
Small Update........That jacking point is a minimum of 700mm or 27.5inches from the front of the car to its center bolt and I have another jack on order so its untried
As another update I have bought another air jack the company that bought the other one stopped making ones with long handles in fact stopped
They are all much the same this lifts from 150mm to 400mm and lifts the front effortlessly in 2 or 3 seconds. I think they have a small advantage over my trolley jack as it lifts vertically whereas any trolley jack's arm lifts at an angle and sometimes the wheels don’t move on rough surfaces
However, this Bilbo is hardly small with a 60" chest and that means a very raised car.
My Sealey 3 ton each axle stands raise from 285mm to 420mm but with the jack under the centre lift point the best I get is the low setting and this is too low for me to remove the underside engine pan to get at the drain plug for an oil change being the whole point !
But with 150 x 100mm wood below the jack (see images) there looks enough room BUT the car sits at a rather sharp angle. Wood under the air jack I think safer than on top of a trolley jack ?
However at that angles I would need to lower the car again to guarantee getting all the oil out !!!
Still it proves that jacking point works as the maintenance manual states
Sigh Oh for a garage with a hoist but in the UK planing says in town maximum height for ones 2700mm or about 12' 10"
Around here the water tables about 4foot down so no maintenance pit that building regs say very correctly need ventilation and flame proof lights
so some images
Jack lowered 150mm high jack fully raised 400mm high Jack partly raised below front centre jacking point jack on 100mm block overall 500mm high
