Now I have seen plenty of write ups on how to fit a Surf Transfer box(130 series electronic 4x4 engagement) onto a lexus auto. Non these boxes share housings just like supra and many other vehicles fitted with this series of aisan gearbox. Even the asian warner box fitted to other models looks very similar. Now my question is how long are these setups lasting. Specifically the rear bearing in the transfer adaptor housing as the oil feeds to this bearing and the rear housing bearing in the lexus box are very different. Non of the write ups have shown any mods to the oil system. Now its possible that there is enough oil splashed around the box to lubricate the transfer housing bearing. This is one problem with forums, lots of info often lacking the finer details and very few followups on lifespan and faulures. Ill show some photos to explain.
