Travel should be limited by the stops, if it were not they would get buggered when off roading.
Travel is limited by the shock absorbers. The bags cannot be over extended unless you have standard bags and have fitted extra travel shocks. Not a good combination.
that is exactly what i thought,so why the bull****!,came from my ex garage mechanic well he is now!

because you can strain bags by lifting vehicle on chassis and suspending axle we had them blow off bottom before after doing such
That should not happen with standard shocks, maximum articulation over rough ground should be possible were the axle is prevented from travelling any further downwards by shock absorber. However it will happen with standard bags and extended travel shocks as stated earlier.

they were std shocks ,it does happen you try it ,it doesnt happen every time but it can,and it was the only vehicle that at time landrover stated not to use lift system that didnt support axles
I always jacked my old P38 on the chassis without any problems!
But I've just checked the RAVE manual for the P38 and the jack that is supplied with the car slots in the axle for both front and rear jacking procedures.
The L322 jacking points are on the underside of the sill (chassis). Just forward or behind the the wheels.
The air suspension is considerably different on the L322 though.

Well the L322 doesn't have a seperate chassis, does it?
I thought it was the height sensors that were vulnerable when jacking on the chassis, but I've always done it. It's hopeless trying to get a decent jack under the axles.
Bit hard to change the airbags when jacking up on the axles too!
Not saying it didn't happen just saying it shouldn't. Full articulation to the extent of the shocker travel should be available without the air bag popping off. It's a seriously bad design flaw if that is not the case. Personally i would not jack the body and hang the axle. I would jack on the axle, stand the body, then lower axle with jack for support. Never the less it should be possible to hang the axle on the shocks without any damage and without the airbag coming off. It does say somewhere in the manual not to activate EAS with shockers disconnected.

i would agree with you ,when we first worked on them we used to put them on 2 post lift because i find access better ,it was usually not straight away but a few miles down the road that they blew off ,we were able to refit with great difficulty and wernt a problem afterwards ,maybe hanging axle on 2 post lift was borderline as we had worked on some before that hadnt come off ,but we did ring local dealer and he told us not to use 2 post lift because of this possibility we hadnt put 2 and 2 together at that time ,but i have never heard since of any problems with bags coming off
Only thought on that would be. IF they were lifted from access height or bump stops with little or no air in them they could get pulled off or dislodged by vacuum as axle dropped. But they certainly should not come off hung on shocks lifted from standard or high profile height.
Think the only thing that could cause that is hanging axles with no air in bags. If you must do it, just pull pipes at valve block so you don't get a vacuum.
PS. Remembering of course to put some air in bags before letting it down.
