I always struggle to get the rear of the car high enough and supported, mainly due my jack being so big.
I've put it on a point which I think is same as DTM's in his guide, is this secure? :-/

I'm also not sure if I've got it high enough for when I drop the diff :-/

thats not supporting the bit that needs to swing down when you loosen the diff is it?
-
no don't think so, better angle....

Better indication of height, last time we did TB's set i remember having to take the wheel off :(

But looking at DTM's photo, I can't see where else the stand would have gone. :-/

I tent to fit both the jack and stands where you have your jack positioned.

I do that when removing the rear wheels, for things like brake servicing, as I don't need much height. I have a small jack, which fits there nicely.
But the large jack which gets the car high enough, is too big to put the stand there :(
The small jack is not man enough to get the car high enough, unless I remove the wheels to give me extra space :-/
-
my jack looks bigger than yours and fits....just needs positioning carefully.
As long as the trailing arms can drop you'll be ok.
-
yeah it will drop ok I think, was just not sure if that position was secure enough.
-
You'll need to take the wheel off. No need to drop diff - use spring compressors and the spring will come out/go back in no probs :y

Don't really like spring compressors, done a Senator & two Omegas via DTM's method:

But each time I had expert guidance!

Leave the jack in place and build up the area under the sill with wheels/blocks of wood/etc.as well as having the stand in place, as an insurance.Nothing worse than being under a car if your not completely happy that its secure.Makes it difficult to concentrate on what your doing I find.

Very true, exactly why the stands are there, plus jack. Wheels have been removed and placed under the sills :) :y

How much force should be required to pop the shock bottoms out of the recess in the rear hub assembly? Both appear to be stuck fast, do you just pull them out while lying under the car?
I've tried hitting the bottom part from the outside :-/
-
I know saloons are different fit to estates.....but I found it easiest to undo the top bolt.
Saloons should be quite easy though I think
-
The foot saddle on my 3ton Yankee is larger than that on yours so i normally get it positioned at the back edge of the triangular plate.
Jack the rear up as high as needed ,for springs doesnt really need to be more than second hole on stand.
There is enough space to then get the "Y " of the stand at the back of the triangular plate to hold the car.
I fould best to also leave the big jack in place just let it down so holding on the stand and tighten up handle lock.
When dropping diff had a second smaller trolley with wooden block on the saddle and it allowed the diff to drop as required.
-
big hammer and the extension pole to my jack did the job, but now i'm confused. Done everything as per guide, Antiroll bar bolts, brake lines, shock bolts, 4 diff bolts removed, but the diff is not dropping? :-/
-
Nfg. It wont work like that.
The stands are on the subframe, which need to drop with dif in order to get the springs out.
The stands need to go on the under body of the car chassis. Look by the exhaust hanger, there is a metal bracket looking thing on the floor pan right next to both exhaust hangers on the v engine cars. Put the stands there. You may need to place the jack on the outboard most part of the triangular plate centre bolt for the rear donut bushes, in order to get the jack outboard enough, or it's in the way of the stand in that location.
Make sure the stand is on the bracket section, not the floor pan itself, or it will bend the floor. Although if you look closely, as if it was s v engine car with two exhausts, there is nowhere else to put the stand.

Crud, just got to the point of lowering the diff. Thats why :-[ :'( :(
-
Which side are you doing first ?
If o/s nothing left if you have undone the 4 diff mountings /bottom rear shock bolt completly removed/abs sensors unplugged and rear drop link .
Try just gently jacking the diff up and then releasing to get it moving,but in truth it should all be free and its own weight makes it drop...naturally supported by the jack !!
You have undone the correct 4 diff mounting bolts have you ?

Yeah, but like an idiot i put the axel stands under the subframe :-[

Stop,
See above post. You need to reposition the jack and get the stands off the subframe.
But when the time comes, put the jack Handel In between the hub and shock, and lever the shock off with that, they are stiff, like a press fit.
-
shocks already popped off, i now need to re-position the stands (need to bolt the diff back up again first!)

Easier with spring compressors :) ;) (whether you like em or not ;) )
-
Depend on which type of compressors available. Mine are fine for the front, but no way will they work on the tear.
-
That's if T has any at all. But this way he doesn't have to buy or borrow any. Spring compressors take forever to wind up.
-
I don't have any compressors, i used them on the front springs, just did not like them.
Its all done now, I moved the stands, luckily I have a spare jack and stands, so did not take long.
New springs are fitted, diff is back up & bolted :)
It actually went rather well, apart from putting stands in the wrong place, I managed to remove all bolts without sheering them, I was also man enough to release them all :o
I want to remove the old shocks, now I need the second pair of hands.....
-
don't know about saloons but my shocks were stuck fast on the bottom mount i ended up putting a ball joint remover fork in the hole and whacking it with a mighty big hammer and that did the job, p.s why do you need an extra pair of hands for the shocks??

Because the top bolt was stuck, had to file an edge into the shock itself, so could use big pair of grips to hold it, while I undid top bolt.
I had the shocks practically all done by time fat man arrived, was just doing the torque on the ant-roll bars.
So its all set now, had new front suspension around 6 months ago, fresh set of boots and a quick check up at WIM at my trusty old steed will be in not too bad of a shape :)
Tomorrow (if the weather stays nice) its getting new air filter, new coolant bottle & new plugs!
