Eibach springs & vibration
Dear all
Just changed stock springs on my 04 SWB G500 to Eibach items obtained from ORC. The car now sits about 7 cm higher. I have changed nothing else (except new bump stops). No spacers are fitted.
Dampers will also need updating because springs are considerably harder and damper rods should be slightly longer (I intend to fit adjustable Bilsteins from ORC calculated for said springs). Wheel tracking has not been re-checked and the steering wheel is now abt 5deg off center when the car goes straight. The car does not pull either side.
At low speed on perfect tarmac (and with the stock shock absorbers still fitted) there exists a discernible vibration felt all over but especially through the steering wheel. At higher speed it appears to dimish to the point of almost not being felt.
Note that when the car was fitted with the OM springs there was absolutely no vibrations.
Any ideas?
Can the cause be traced to the changed geometry?
I would say that rhe geometry of the prop is causing the vibration, come across a few guys with 5cm lift on 463's and they have had vibrations , double Cardon prop has cured it, but not sure why it would change your tracking
you will have to use a landrover one and make an adaptor plate.

Gearbox and transfer case mountings are a common source of vibration problems. Good to renew. The TC, if I recall correctly, is chain driven and rough-shifting can probably stress the chain and cause some play. I think on early Gs the intermediate shaft is greasable, but on later ones it appears sealed with rubber covers over the joints.

This is correct: in 460's and early 463's the short propshaft has three grease nipples: one in each UJ and one in the middle joint.
Maybe your former springs were so soft that they would absorb any discernible vibration....?

Can you share some more info on that modification?
Can you please provide some details on the "double Cardon prop". I cannot claim that I know anything about it (or where I can find it).
Many thanks
