Well, i had to remove the prop & half shafts so at least thats allready done.  will it now be possible to just unbolt all the diff bolts and pull the old one out, and then weld a new pan on? or will i have to remove the whole axle?

Been there, done that Skippy.

The worry is when you start to enjoy doing the repairs.

Youre right there, it was a relly good laugh getting under there and removing the prop & half shafts so i could get home!  There were also plenty of helpful people who were quite willing to lend me their tools.

Two valuable lessons learned:

1: Leave the lead foot at home when offroading.
2: Remember that i drive a Landrover and always carry tools :oops:

You don't have to remove the whole axle if you can weld upside down.  The biggest issue is making sure you don't get any pinholes in the new pan.

Removing the diff is straightforward enough, just unbolt it and give it a tug and a wiggle.... watch out...  It's HEAVY

To remove the rear axle clamp the break pipe, undo the braek pipe,
undo the A frame bolt, (you may find it easier to remove the two horizontal ones and leave the ball joint on the axle), remove the bolts on the trailing arms, then jack up the body and wheel the axle out.
Refitting is the reversal of the removal procedure.

Isn't that Haynes speak for "We've taken it apart but we've not worked out how to put it back again"
