Just wondering how hard it is to change with the car just on stands?

What do u reakon?

and if someone can run through everything thats needed/involved with changing diffs it would be greatly appreciated.

cheers lockz

Reckon that changing it on the ground will be difficult but not impossible. Probably be easier to start with the trailing arms and then lift the diff up using strategically placed jacks. I have never done a diff in a coil spring rear only leaf spring which is f**k easy. Someone else here may have better advice or more experience than me.
Good luck 8-)

1st jack up back end and safty stand (a must)
then you have to pull your brake callipers off (4 bolts) 2 each side
to lift the diff up and down use the trolly jack

undo (suport diff with trolly jack)
hand brake cable (1 bolt then un-clip it)
sway bar bolts (2 nuts 2 bolts)
shocker bolts (2 bolts)
top control arm (2 bolts)
lower control arm (2 bolts)

drop it out

put the new one in
just make sure you get the
sway bar in the same spot

i think the best way to put it back in is
control arms first (top and lower)
get your sway bar in the right spot
then shocker bolts then handbrake

a single person can easily change the diff, its not hard... a trolley jack holding the diff is easy as the diff isn't badly unbalanced... just take ur time!

ohh and if you have a bike hanging from the roof of the garage... remove it!
I found out with the chainwheel hitting my head whilst it was falling on my rear quater

Could not have said it better myself. The ONLY thing you actually need the second person for is bleeding the brakes. (Having 2 people would make the whole process quicker though).

No offence to your mate, but that is your first problem. The last person to ask for advice is a dealer mechanic.

As yes, Nick has said, they are piss easy to change when the car is on stands. I've changed more than I can count, all on the floor. Should be in and out within 60 to 90 mins with a mate, maybe 2 hours if you do it alone.

And dont disconect the brake lines, just remove and let the calipers hang and pop them back on later.

ROFL... Easily baited there man. I was waiting for a reply. :wink:

No, not all dealer mechanics are bad. I know the specialists are very good at their job. But the general service centre mechanics can leave alot to be desired at times.
