If its just the stub axle thats snapped as above its four bolts to remove it, theres a possibility other things are bent but you could fit the stub axle and take it to a specialist to see if theres anything bent that cant be seen by the naked eye.
Get a 172 cup stub axle tho as they are a different offset iirc.
You will need a new back bumper about £30 second hand and a your rear quatre sorting obviously.
Excellent.. Any idea where i can order the correct stub axel online?
Also how do i go about getting rear quarter sorted and how much it might cost? Sorry if these are obvious questions but when it comes to car problrms im clueless.
