What is safe to use as a jacking point?
Where would you put (an) axle stand(s)
Any pics would be welcome!!

1) any part of the main chassis rails
2) any chassis outrigger
3 ) any chassis crossmember
4) front bumper
5) diffs (if need to get the wheels off the ground and dont need to work on the suspension, use a bit of wood on the jack to protect the diff)
6) underneath the radius arms/trailing arms on the axles (if you need to tip the car slightly, e.g. when you are changing halfshafts and dont want all the oil to fall out)
Axle stands -
1) any part of the main chassis rails
2) any chassis outrigger
3 ) any chassis crossmember
4) on the axle tubes (front or rear)
When using axle stands use a pair and space evenly across the width of the car, check for stability by rocking the car before lowering the jack completely
Sorry no pictures, but all they would be of is a jack under a land rover and i'm sure we can all imagine/remember what that looks like

I've always been wary of jacking under the radius arms, as I never thought that that bolt from the radius arm to the axle was designed to take 1/4 or 1/2 the weight of the truck.
But, hey if someone who knows more than me says it ok, then that'd be handy, as it's much less of a reach to the arm than it is to the axle.

Radius arm is attached to the axle by 2x 8.8grade M16 bolts, the 8.8 part tells you how many tonnes per square mm (IIRC) the bolt can withstand before shearing (IIRC, it could be tension). Anyways, the calcs will tell you that they will easily withstand the weight of the whole truckI've always been wary of jacking under the radius arms, as I never thought that that bolt from the radius arm to the axle was designed to take 1/4 or 1/2 the weight of the truck.

Jacking points with trolley jack or bottle jack -
1) any part of the main chassis rails
2) any chassis outrigger
3 ) any chassis crossmember
4) front bumper

I'm a newbie so please bear with me...
I need to change a tyre on my land rover 90, which I've only had for a fortnight (it's my first) and the things I've read make me nervous about just using the simple jack that came with it, it's bog standard. Do you think the original jack will be sufficient for a simple tyre change?
My next question is where should I jack it up using this? As it's not a bottle or trolley jack do the same places apply as per Lewis' post above?
Sorry for sounding so girlie, but I just have no idea where to start and couldn't find anything in the workshop manual about jacking points.
Any advice appreciated, thanks.

also before jacking the vehicle, even if it's just to change a wheel/tyre, the Defender owners handbook says 'apply park brake, engage 1st gear & low range & engage diff lock [fully engaged when the dash warning light is on] always chock the wheels fore & aft except for the wheel ['s] that will be lifted clear of the ground
then slide the jack round fitting into the hole & set it up to lift, just lift the tyre so it's clear of the ground & allows you to remove/fit the wheel/tyre assembly. also do not leave the vehicle unattended while the jack is holding the weight.

no probs Andy, under the front bumper you should find 2 rectangular rubber bungs & in the rear crossmember you'll see 2 more circular holes these are the standard 90/110 jack points, on the front take out these rubber bung/s for which side you want to lift. then next step is -----------
then slide the jack round fitting into the hole & set it up to lift, just lift the tyre so it's clear of the ground & allows you to remove/fit the wheel/tyre assembly. also do not leave the vehicle unattended while the jack is holding the weight.
Western,
Thanks so much, that's exactly the information and reassurance I needed. I now feel supremely confident in attempting my first bit of land rover maintenance, albeit a simple tyre change... one step at a time eh!
Cheers,
Andy

also undo the wheelnuts 1 full turn before jacking up the tyre from the ground. take your time & do not go under the vehicle while it's jacked up.
Will do - in fact getting the wheel nuts off is my biggest concern, being a bit of a girl... literally ;-) I shall have a can of WD40 to hand!

I think it's measured in NM not tonnes.. I can't remember how it's worked out, but a 10mmx60mm (I think) 10.9 HT bolt can take 69 tonnes... don't quote me on that!Radius arm is attached to the axle by 2x 8.8grade M16 bolts, the 8.8 part tells you how many tonnes per square mm (IIRC) the bolt can withstand before shearing (IIRC, it could be tension).

I only learned that after a quite embarrising conversation about bolts with a guy who knew his onions at a bolt shop.
How do you jack up both wheels on an axle at once? I have a pair of 2 tonne axle stands and on the box it says don't have the stand at one end and the jack on the other end, so how do you lift both ends simultaneously and then put a pair of stands under them? My guess is you can't, with one jack?
Since I heard a nasty cracking noise when I used the rear jacking points I'm doing all my jacking on the axle, as I only do it to change wheels over anyway... that was worrying, and while some of it has had welding attention I still don't trust it enough to be working around it while it's jacked up using the cross member holes.

A couple of tips.
Before you start to undo the wheel nut.
Take the spare out and place it under the vehicle. Just in case it decides to drop....
Throw the Land Rover wheel brace away and buy an impact type deep socket along with a good knuclke bar. Then aquire a length of pipe that will slide along the knuckle bar to make an extension bar. You shouldn't have any difficulty.
Always torque the wheel nuts up after changing a wheel. If you have to change one at the roadside then torque up as soon as possible.

Hi Andy -- a even bigger welcome then,
I use one of these wheel braces
http://www.johncradd....asp?prodid=193 with a suitable internal diameter extension tube to fit the handle say about 3 foot [1 meter] long, you shouldn't have any problems.

My jack worked really well and was so easy to fathom (as was the front bumper jacking point - thanks Western). My jack had a racheted handle which made life easier and seemed very sturdy, although I will look into getting something a bit more meaty for future jobs and a pair of axel stands I think.
I did need help to loosen the wheel nuts initially, but everything else was plain sailing. However... I did make the mistake of putting the spare wheel nuts on top of the number plate light housing as I took them off assuming they'd be easy to find when I put the punctured wheel back on the rear door. Once changed I decided to simply throw the puntured wheel in the back... and forgot to collect the wheel nuts from on top of the light housing - DOH! Amazingly only one fell off on the journey to the tyre garage!
All-in-all I feel far more confident now about attempting whatever comes next - so a very big thank you to all of you for such really useful advice.
Andy.

when you get round to buying axle stands & trolley jack, go for items with a minimum of 2 tonnes rating.
