hi guys i am in australia dont know if it makes a difference!
i have a 2001 liberty/legacy, 5 speed manual, 2L motor and is a sedan.
after driving on the freeway for about 20 mins i get a violent shudder all through the vehicle, in my time as a mechanic i have never felt this before.
i have been told by a gear and diff specialist that the car in its time has probably had a gearbox change and the gear ratios messed up and the viscous coupling in the transmission will have failed.
is this true? and easy fixes? should i go for a second hand vc or transmission? does the vc need to have a certain gear ratio?
