What you need to know

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.
