Revision as of 23:55, 30 October 2012

Datsun 1200 cars (sedan/coupe/wagon) use an H145 differential in the Rear Axle Assembly.

Differential Repair

Replacing diff bearings or spider gears? Or ring & pinion? The procedure for re-assembly the differential gear carrier is very complicated. Be sure to get the factory service manual.

We recommend: Just swap the whole center section "pumpkin" from a 1971-1973 B110 or 1974 B210 in there. It will be cheaper and certainly easier, someone has one for free. The center section rarely goes bad unless the diff runs low on oil, so your chances of getting a good used one are high.

Yes, B110 and 1974 B210 center section is identical. You could also swap a 1975-1978 pumpkin they say you need a 2mm spacer between the pumpkin and the housing.
