tell me about it mate, i was doing about 40 on a country lane and went into a hole about 6" deep and heard a big fucking bang!! I too checked for Sump but was fine, on the way back turning right into a road was 2 potholes located 1 after the other, driver side rear wheel went into both, and thanks to that shit that suspension needs to be replaced. It is really pissing me off, there are still so many around here, some are unbelievbly deep and wide, yet not filled, some smallers ones have been filled, forming a bumpy texture...
