alrighty... dropped the box and found i had a noisy throw out bearing and exessive play in the retarded dual mass fly wheel. both spnning back and forth and also rocking it side to side.
so, found the problem?? so i thought.
3 hour drive into Rockhampton to get the new heavy duty clutch and solid fly wheel and then 3 hrs back home.
had a look at the part number and it wasn't a H.D clutch so another 6 hr round trip to Rockhampton the next day. got back home at 3pm and had everything back together by 6pm.
dropped the car down BUT.... the friggin noise was still there...........
dropped the box back out a week later and have now got a bearing kit for it.
So with the box in 100 and 1 pieces we.ve found that the hardenning has come off the back of the main shaft where it meets the input shaft.
with a new clutch, solid fly wheel, bearings and a main shaft for the gearbox there shouldn't be anything else that could go wrong.. with the box that is.
pretty confident in saying that this will be the 1st and last Nissan i ever buy. 4yr old and only 87 000km on it.
