OK, so i am driving down a slip road onto the Motorway, when i cross the cats eyes the front end starts shaking very violently, i am thinking christ a wheel is coming off, so start braking onto the hard shoulder, down to about 10 mph and it stops, so i speed up again and onto the motorway and all is fine ? what the flip could it be ? drop link ? ( do they have them? ), please tell me what you think , or has it happenend to you ? if so what was it, been fine since just i am abit nervous now, cant see anything hanging off or loose.
