Changed all three mounts on mine this afternoon. Following Hippo's excellent write up, I reversed the car up on to a set of ramps to give me extra room for access. Slackened off all bolts on the three mounts first then removed the r.h. rear mount. Moved then onto the front mount-I agree that it takes a bit of pushing and twisting to get the mount out and the new one in but it's just a matter of persevering and getting the angle right. After the front mount was fitted, I inserted the bolts and left them finger tight. Replaced the rear r.h. (U.K. drivers side) mount and also left the bolts finger tight. Finally removed and replaced the rear l.h. mount (U.K. passenger side) then tightened all bolts starting with the rear l.h. followed by rear r.h. and finally the front mount. Access to the bolts is not too bad but not much room to swing a normal 1/2" ratchet for the top diff. bolt on the l.h. mount as the rear silencer (TD4) restricted movement to a couple of "Clicks" at a time.
I did it without resorting to my usual cussing without dropping the subframe or bending mounting brackets out of the way but I agree that dropping the subframe slightly would assist with removal of the front mount but the job would, overall, take longer.
Just remember that the longest protrusion of the bush from the mount bracket faces towards the diff. and the rear brackets are "Handed"- a mirror image of each other. I say this just in case you open the boxes, take the mounts out and put them in a pile !!
From start to finish, took me about an hour.
I gave the bolts a smear of copper grease before reassembly
Hope this helps
Spanner sizes:
Diff to mount bracket 13mm A/F
