after just getting my tailshaft centre bearing replaced, I installed the tailshaft and went for test drive. all was well no noise liek it had, very smooth so seemed that the problem was fixed, turned around 2km up the road headed home then all of a sudden car shuddering, loss of power, engine sound was not good, there is a bit of a ticking sound coming from the engine, the car has a a huge shake when stationary, give a little revs and that shake goes away. Is this a bent rod or somthing else? sorta sounds like that ecu was taking all the timing out and just no power at all. neep help ??????
