hello, im new to the forum, and joined to get an answer to an annoying thing happening to my 2008 discovery. when driving at approx 60-75 ish, mph, its rocking from side to side, and is very unnerving, almost as if it wants to tip or slide. when you go above these speeds its not as bad, its as if it then sticks itself to the road. this is my second disco 3 in 2 years, and the previous one didnt do it, mine does have the uppy downy suspention as we call it, unlike the previous that didnt. has anyone got any helpful advice, as dont want to goto dealers and get fobbed off. thankyou for any helpful advice, regards, edwina.
