steering lock up

[silcoon]

I BOUGHT A 4864 IN FEB. 2008. WHEN THE HOUR METER ROLLED AROUND TO 48 HOURS THE JOY STICK LOCKED UP. MONTANA WAS GREAT IN HELPING SOLVE THE PROBLEM. NOW THE HOUR METER IS AT 50, ONE MONTH OUT OF WARRANTY AND THE STEERING IS LOCKED UP. THE HOSES AND CYLINDERS PUMP EXCELLENT PRESSURE BUT THE STEERING WHEEL IS LOCKED UP. STILL TRYING TO WORK OUT THE PROBLEM WITH MONTANA. H-M-M-M HAS A LEMONY ODOR TO IT! SIL
