Jacking
Jon
My Series 3 didnt come with a jack (not that i expected it to) so i treated
myself to a 3 tonne high lift trolley jack. Where is a safe place to jack
up the car to remove the wheels and examine brakes etc? I dont want to just
slap it anywhere incase i kill my chassis or something equally as
horrible!!!!
Thanks all

enough to get both wheels off the ground, and put the vehicle on blocks befor
removing both wheels, or even all wheels.
Unless its really old with a very corroded chassi you won't do any damage by
using chassis members as jacking points either but the most conventional place
is still under the diffs.

Under the diff housings are a fairly safe bet for jacking (although the car
will lean a bit to one side because the housings are off-set). Unless the
chassis is really rotten you should be able to jack on that as well - it
really depends what job you are trying to do. I would definitely go a treat
yourself to a pair of six tonne axle stands before even considering sticking
any part of your body under the car - ie a jack by itself is OK for changing
wheels but it is not safe for anything further than that.
Have fun!

Jon, if you are going to jack your heavy car up using the diff housing,
place a block of wood between the jack and the diff housing. A piece three
inches thick should do it. You don't want to bend the flimsy outer pan or
even worse crack the diff housing do you?
Personally, I always jack up using the bottom of the spring plates and then
PLACE A HEAVY DUTY AXLE STAND UNDER THE AXLE BEFORE DOING ANYTHING ELSE -
C'mon guys, this is elementary safety procedures..........

I accept there is a risk of damaging the axles by jacking under the diff but
I have never had any problem - the big advantage of this is that it lifts
both wheels at once. I NEVER do any work on the Landy (or any car for that
matter) without it being firmly supported on axle stands.

Jack up the car under the diff (via a block of thick wood).
Place axle stands on each side under the axle near the wheel??
Lower to the stands
Is that right?? Also, if i jack on the chassis, should i use some wood also
to dispurse the weight??????

very questionable whether it is safe anyway! If its that rusty its in
need of fixing or replacement.
In the interests of your continued health, you might want to think about
adding some wheel chocks to your armourery, and engaging four wheel
drive before lifting the thing. Remembering that the handbrake works on
the rear most drive shaft is also worth while, especially if you have
one side up. (Diffs and all that).
Your description of how to use the stands sounds fine - but personally I
always jacked my Series under the springs and did each side
individually. Take care, Mike.

Hmmm, I'm wondering if this is a cause of so many Landies having leaking
front diffs. By doing this, you are placing a lot of strain on a thinnish
casting. Lets face it, nearly 75% of the vehicle weight will be resting on
an area no larger than a 50p piece, and one side is solid via the jack head
and eventually floor, the other is a hollow casting. I wonder which is going
to give first?
Mike sums it up perfectly in a later post. Safety first and never balance
the car so both wheels are off the ground at the same time by jacking the
axle/diff casing up. Always use the bottom spring plates on a series or any
leaf sprung vehicle. As well as axle stands, chock the rear wheels, engage
1st gear and 4wd and never ever trust your handbrake.
It might take a little longer to do, but I'd rather take the extra time than
have a couple of tons of LR on top of me........

What you wrote about jacking under the differentials makes sense so I
thought I would do a bit of a literature search on it. None of the Land
Rover workshop or user manuals that I have looked in (the official ones for
the Series III, 110/90, Discovery and Discovery II) and several of the
Haynes jobs make any mention of it at all. They refer to using the vehicle
jack under the axle tubes and the location shown in a couple of diagrams is
exactly where you want to put the axle stands. I am surprised that the
books don't say either 'you can safely put a jack under the differential
housing' or 'never put a jack under the differential housing'.
Are there any horror stories out there about people jacking under the diff
and having something break?

be off centre so will not lift both sides evenly.

Thanks for that, I feel a lot happier continuing to jack under the diffs
now.

It's up to you. Personally, my own engineering intuition, common sense and
everything else tells me not to jack any vehicle under a diff housing.
Safety alone should tell you not to do it as the vehicle will be lob sided
due to the diff not being central. At least jacking under the spring will
keep three wheels on the ground.
I wonder if the folk who say it's ok to jack using the diff housing would
jack the car up using the sump??????? DON'T do this though, it's meant as a
joke...........
Again it might be a cause of so many LR diff gaskets leaking......and who am
I to argue with a LR manual?

section in it to the one you posted. I was looking for 'jacking' and it was
under 'lifting'. I could find no mention of it at all in any earlier
manuals at all.

I was going to say that I had seen tyre centres (Quick Fit, High-Q etc)
using diffs as jacking points to support the case for using them as well.
But having seen some of the other things that these places do I decided this
was not exactly proof positive that it was any where near accepted practice.
I think you are right that jacking under a diff is inherently less safe than
some other locations that can be used. I always make sure that the weight
of the car is supported by heavy duty axle stands before even considering
putting any part of my body under it.
On the subject of dangerous jacking, The most scary situation I have ever
seen was a chap lying underneath a mini working on the inner CV joints with
the car supported by a single scissor jack at full stretch placed under the
middle of the sump!

Yes, so have I (shudder), but there again, what do these people know? It's a
bit like Halfords servicing your car..........If you know what I mean.
Similar situation to your scary moment, except this was worse.
Guardian Royal Exchange (name dropping here) sent me a mail shot to take up
house and personal accident insurance some time ago. The design was very
clever as it was a fold up house portraying all the dangers and how simple
things could be potentially disastrous in the home. It was a cartoon type
drawing, but not very funny. It merely pointed out places like electric
sockets and the fact they shouldn't be overloaded etc, but the drawings did
not show 10 plugs in the one socket, just an arrow with a comment box. When
you got to the garage, there was a guy under a large car being supported by
a scissor jack under the sump. No mention of this though, only not to store
inflammable liquids........Someone should have been shot for this.
As I said before, it's up to the individual, but I value my life a bit more
than to take the risk of jacking under a diff.
Totally agree with you though on the correct usage of HD axle stands.

The Land Rover Workshop Manual for the Series II Range Rover says to
do just that, but it doesn't work! Jacking under the diffs is too far
off-centre to lift the vehicle evenly.
I usually put the jack under the axle housing lifting each side one at
a time and that seems OK.

and to quote Land Rover's own Defender Workshop Manual:
Raise the front of the vehicle
1. Position cup of hydraulic arm under differential
casing.
NOTE: The differential casing is not
central to the axle. Care should be taken
when raising the front road wheels off the
ground as the rear axle has less sway stiffness.
2. Raise front road wheels to enable an axle stand
to be installed under left hand axle tube.

other than a very satisfied customer have a neat adaptor plate that sits on
the cup of a Hydraulic jack and has extending arms to reach under the
springs, thereby jacking the centre of the car up and lifting both wheels
safely at the same time. Price is around the £25 mark. They are online at
www.notherntooluk.com part no 145883e.

Maybe, but the original post was about a SIII. Either way, I would not do
it. Incidentally, Northern Tools - no connection other than a very satisfied
customer have a neat adaptor plate that sits on the cup of a Hydraulic jack
and has extending arms to reach under the springs, thereby jacking the
centre of the car up and lifting both wheels safely at the same time. Price

Depends
If I'm just lifting one wheel then the bottom of the radius arm / spring
plate is OK but hard to get an axle stand in.
If you have a jack with a nice big top - mine has a bowl about 6" wide -
then jack under the diff, place an axle stand then let the jack down so that
it is no longer putting pressure on the diff but is just touching it - in
case of the axle stand getting knocked over etc...
If I'm lifting the whole end, I always use the diff.
Jacking off the chassis should be fine!
