2 post ramp not happy lifting Discovery 2

I have seen under a Disco 3 and it had weights hanging off the chassis!!

I believe Land Rover do it intentionally to bring up the kerb weight so that it can tow more?

The weights are harmonic dampers. LR started fitting them in the 90s to the Range Rover Classic and carried them over to the Disco. On the early cars they are a big steel disc fitted in the front steering damper bracket, Discos then sometimes had them on the rear axle also. I think with the Disco 3 there are a pair on the rear frame that pivot?

They are to make a ladder chassis truck feel nicer at speed on road and they weirdly work. The late Classic and early Discos also had damping weights underneath the swivel housings.

When you fit them to a Classic that you genuinely feel a difference at high motorway speeds. Much less chatter through the steering wheel. I don't know how they work and when you first notice them you certainly wonder what on Earth they are doing. They are part of the reason why a Disco 1 drives so much more nicely than a Classic when to all intents they are the same vehicle.

Good to know.

From the RAVE workshop manual for a P38 Range Rover - I know they're not identical, but it might be worth checking what they advise for a Disco 2...


TWO POST VEHICLE RAMPS
The manufacturer of RANGE ROVER VEHICLES
DOES NOT recommend using ’Two Post’ ramps
that employ four adjustable support arms. These
are NOT considered safe for Range Rover
vehicles.
If a vehicle is installed on a Two Post ramp,
responsibility for safety of the vehicle and
personnel performing service operations is
attributable to the Service Provider.

That's a sweeping statement. Any idea what the danger is? Presumably not simply lift capacity or reach, since it makes no reference to that sort of limitation.

I'd guess - and that's all it is - that as it's not a capacity issue, it must be stability. Might it be difficult to position the arms far enough apart without the centre of gravity of the whole vehicle being rather close to one pair of pads? Land Rover's instruction is unusually emphatic. I'll leave proof of it to the reader. They are equally emphatic about where exactly to place conventional jacks.

Maybe the windscreen might pop out like an old Allegro!
