Posteen Posted June 13, 2022 Share Posted June 13, 2022 I own a Forester 2.0 Diesel with manual gear. 2010-model. Lately, when the engine/car has been driven for a while - something occurs that the mechanic at the garage can’t find reasons for. In example when parking or after a short stop: When releasing the clutch, in low speed and turning the wheel, the car is moving forward with banging noises/makes small “jumps”/choppy movement. It’s really noticeable. Has anybody a plausible explanation for this. They have already switched the clutch and done something on the stabilizer bar. I’m grateful if anybody knows what this can be. Best regards, Peter. Quote Link to comment Share on other sites More sharing options...
Mr B Posted June 13, 2022 Share Posted June 13, 2022 Sounds like all wheel drive binding/hopping/drive shaft wind up, possibly viscous centre differential failing. Will be more noticeable on tighter lock low speed manoeuvres. not keeping tyres all matching make & close wear level can cause viscous diff problems but also high miles, challenging road conditions of ice snow and light off road can lead to occasional failures . Plenty information on google that may help you evaluate/diagnose. Viscous diff binding well known within the industry on AWD vehicles ... Viscous diff not super cheap but hunting around once have part number save good money as can using someone with experience to do the work as they do job faster and with less errors ... good luck ...
