1990-2005 NA/NB Miata rear axles. 1990-1993 1.6 and 1994-2005 1.8/differential arrangements differ; ABS ring, one/two-piece construction and axle hardware matter.

Confirm engine/differential family, ABS, axle construction, spline/flange, side and nut/thread. Diagnose wheel bearing, driveshaft and differential vibration/leak separately.
OEM numbers
Factory catalog examples: 1990-1993 M090-22-510 family and 1994-1997 MD02-22-510A. Current aftermarket examples include GSP NCV47534 early and one-piece 1994-2005 replacements.Supersession
No 1.6-to-1.8 universal chain is asserted. Later one-piece 1.8 axles can replace checked early two-piece 1.8 applications, but a 1.6 differential conversion requires the matching driveline package.
Fitment
Confirm engine/differential family, ABS, axle construction, spline/flange, side and nut/thread. Diagnose wheel bearing, driveshaft and differential vibration/leak separately.
Aftermarket options
New/reman and used axle paths exist. ABS rings may be included/removable depending on part; verify rather than assuming.
Before you buy
Confirm 1.6 versus 1.8 differential family, ABS ring, one/two-piece construction, spline/flange and axle-nut thread. A differential swap may require matching axles and driveshaft.
