1 complete used rear hub / wheel bearing assembly for 1990+ 300ZX (Z32) non-turbo models. These are different on TT vs. NA. Used Twin-Turbo wheel bearings can be found HERE.

1991+ NA hubs included this tab as pictured in the first image above.  There is a dowel pin pressed in the tab that determines if the hub fits on the left or right side.  If facing the front of the hub with the tab up (as it would be installed) if the pin is on the left side, the hub is for the right side and vice versa. Pin can also be removed and bearing can be used on either side.

Note: Used wheel bearings should be expected to have rust on the surface of the hub and bearing as well as studs. Z1 recommends replacing wheel studs on used wheel bearings.

New rear wheel bearings are also available, but require the use of a press because they do not include the hub like this used assembly,
