Removal
1 Chock the front wheels securely. Jack up
the rear of the vehicle, support it on axle
stands and remove both rear wheels.
2 Remove both driveshafts with reference to
Section 8.
3 Unhook the exhaust system mounting
rubbers and lower the rear of the system
approximately 300 mm (12.0 in). Support or
tie the system in this position
4 Unbolt the propeller shaft rear flange from
the flexible drive joint and lever the propeller
shaft from the joint. Support the propeller
shaft on an axle stand - do not let it hang by
the universal joint.
5 Position a trolley jack underneath the final
drive unit, and raise it until it just comes into
contact with the underside of the casing.
6 Unplug the wiring from both ABS wheel
sensors at the connectors.
7 Unscrew the bolt securing the damping
bracket at the front of the final drive casing to
the suspension crossmember.
8 Unscrew and withdraw the bolt securing
the rear of the final drive casing to the
suspension crossmember.
9 Lower the trolley jack and remove the final
drive from the underside of the vehicle.

seems to only list 2 bolts ?

Cool, just FYI, the 3 bolts on the side changed size from around 99iirc, annoying when you're pissing about with digs the night before events and Vauxhall don't do them! Gimme a shout if you get stuck. The 3 on the side are a bit easier to access than the one on the top too :)

Don`t think so Nige ;D ;D ;D Easy enough to do after you`ve done it :D. With the front damper it`s easier to undo the 3 torx bolts holding damper bracket to O/S of diff then lower leaving upper bush & bracket in situ :y
