Disco 2 Suspension

(1/3) > >>

Def90:
I need some advise regards the suspension on my Disco 2.

I have a Disco 2 fitted with SLS air suspension and ACE. I have owned the car for some years and have found it to be very “planted” on the road, cornering is excellent and the only observation I might have had is that the ride was quiet hard.

Recently I had the normal issue with one of the original air springs failing, so replaced them with OEM replacements. These were fitted without issue, re-pressurised and I have been driving the car for several thousand miles since, the suspension ride height is ok and the off road lift works fine – all looks fine.
The question I have, is that since replacing the air springs, the ride has been quite bouncy, it no longer has the confidence when cornering and generally feels like there is more vibration from the suspension set up.

Is this normal, is this what I should expect from new springs or is there something else I should consider, shocks, anti roll bar, SLS recalibration?

Jimbo:
What's the mileage on the Disco ?

You may need to consider new shocks - I got mine replaced a few thousand miles ago, and it made a whole load of difference to the ride.

boss:
yah, that sounds a little odd....our D2 has 2" lift and henious simex tyres and the ride is as smooth as ever! thats an old man emu lift (springs and dampers) from devon4x4 if you wanted to know ;)

thermidorthelobster:
Air is air.  The springs themselves shouldn't affect the ride, it's what's in them that makes the difference, and presumably you haven't suddenly started using different air than before.

Try a decent set of gas charged shocks.  I'd go for Old Man Emu personally.

Def90:
Thanks Guys,
As the ride was ok before the Air spring failed and all I had changed was the Air springs, my immediate thought was that the ride issues were related to the springs.  :-.
But the more I thought about it, I wasn't so sure that the springs were at fault, as they do what they should (ride hieght is ok / 2" lift works fine). Haven't checked the Anti Roll Bar, but see no reason as to why this should be at fault if it was ok before - So the shocks seem like a good bet. However, when I do the bounce test by pressing down on the rear bumper, the dampers stop the bounce pretty quickly. With 120k on the clock, the replacement of the springs may well of shown up the dampers being a little tied, so I reckon these are the next step - I'll check out the old man emu's and report back - Cheers :)
