I have a 03 nrg, and I have just changed the gears as the primary gear went on my old gear box, i changed it over and filled up with gear oil and put all back together, then two days later gear oil has gone everywhere? I cant see the place its come from, Im thinking maybe its the bearing to the wheel (from the secondary gear to the wheel) I cant tell where its coming from anyone else got any ideas? or had the same problem? Thanks James.
Gearbox oil will leak out of , either output shaft seal, overflow , or poor sealing of the plate/cover. If you say it started after 2 days then it may well be the seal behind the bearing. Is your rear brake effected ?
