Well here is the story.... was driving home from work today and took a left turn, then there was a loud shudder coming from the LHR of the car. Took a few more turns and I found out that it only does it when turning left and not when turning right.
I got home and reversed into the drivway (again turning left), this produced that loud shudder again but it was about twice as bad as before. (this also appears to be coming from the LHR)
I has a look underneath and theres not really anything obvious from what I can see.
My best guess is a rear diff.... or something silly and obvious haha.
will be your diff lol mine does it too but thats coz its welded! i would be taking a look at your diff mate i have seen what happens when these go at high speeds (110kmh of course lol) and its not nice could just be as simple as a bearing or low oil but better to check it out now
Thanks for the input. It turns out was something simple and stupid lol. We jacked her up and had a good look underneath, turns out it was just the exhaust rubbing on the body. Funny how it can be something so simple sometimes.
