I have a 2 ton jack and a pair of 2 ton axle stands, but i'm not sure they will be enough to lift and support the truck. I know come spring i'll need to do the front brakes and i may start tool shopping while the prices are cheap.
They will work (2 tons x 4 = 8 tons total weight), but when it comes to jack stands, overkill is always nice. Usually, the 6 ton stands are larger and not as flimsy. Make sure you have some sort of adapter on top, as the "regular" top part of most jack stands doesn't usually fit with the correct jacking point of these unibody vehicles.
As far as a floor jack, you'll probably want a 3 ton jack at least. The diesel engine is a bit heavier than the gas motors. Mind the minimum height, too, especially if you have air suspension.
With the stands and jack you'll never use the ramps. I've got a set that was used once and sits in the garage.
My 2.5 ton 35 year old Craftsman floor jack lifts the front of the Touareg fine.
Don't buy cheap sheet metal stands. Get cast ones with2 tone or better rating.
