One problem related to front suspension has been reported for the 2004 Land Rover Discovery Ii. The most recently reported issues are listed below.
Just got off major highway and car started to vibrate uncontrollably and make a knocking sound and just stopped if a loud nose that sounded like the engine fell out. Cars behind me swerved to avoid hitting me and two people stopped to pushed my car out of harms way. I had to have my car towed and the next day my mechanic told me the drive shaft fell out. This just happened this on 12/2/08 and I have not had it repaired as of yet due to the costly expense.
