Hi. I'm new to the site. Bought my first landrover just before christmas. Well pleased with it. Should have bought one years ago. I'm quite good with repairing most types of car but this has got me beat up to now. When i purchased the freelander TD4 o2 plate no problems with it. But now i have a vibration between 15 and 25 mph. Have replaced drive shafts and lower ball joints. Removed propshaft to eliminate it and diff. Car drives well over this speed but it seems to be worse when i've done a few miles. Also put tyres front to rear. Any ideas please??
