I have undertaken an assessment of the chassis and box section frame assemblies at the front and rear of the vehicle. There is clear damage and impact distortion to the right hand side of the rear chassis box section frame and rear right arm clevis. The extent of this damage does not appear ,at this time, to continue much further across the chassis or into the frames, it seems to be localised to the right hand rear area surrounding the clevis. The impact has caused the rear frame out of square by as much as 10mm in places, some gussets are also damaged and distorted. In order for the frame to be repaired I would need full access to the area and would suggest that it is necessary to remove the engine, gearbox, sump and differential as a minimum in order to gain the access needed to repair the frames correctly.
