simpled88 New Member 8 Member For: 10y 9m 7d Posted 31/03/14 08:27 AM Share Posted 31/03/14 08:27 AM Hi all,I have had a look around but I haven't come across this yet (or if I have I didn't get it cause I'm still learning about everything). So the story goes... when I drive long distances I notice the back of the car has a bit of a knock happening. I cannot pin point it yet but I know it feels like it is coming from the back. The knock only happens when I accelerate from stop (no other time does it happen) but only happens for a couple of meters then its fine. Its not a violent knock just more of a wobble. Now if I take it to a mechanic I know the problem won't happen cause it wont have been on a long drive (by long I'm talking 1hr+) so I have come on here to ask to see if anyone has had a similar problem or knows what they think it might be. My car is a 09 FG XR6T auto. Thanks. Link to comment Share on other sites More sharing options...

We are going to drop the cradle to reseal the diff and have a real good look at all the bushes Link to comment Share on other sites More sharing options...

Is your problem happening the whole time or on after long drives? I thought if it was the diff that the problem would happen the whole time but I dont know too much about cars yet haha.

I thought if it was the diff it would happen every time I drove it? how much am I looking at if it is the diff bushes roughly? Link to comment Share on other sites More sharing options...
