This spare part has not been released yet. You can tell cause TamiyaUSA is still showing "out of stock". If you get really desperate, you can always purchase the DB01 WO universal set front or rear. These are the same parts found on the 511 and include the shaft, axles, pins, etc. The fronts pair even include bearings and uprights. Leave it to Tamiya to reinvent the wheel (or axle
). I still think it's INSANE that Tamiya is running a 950 bearing in the front of their off-road car now. These bearings were the bane of everyones existence when they used them in their touring cars for all those years.
