Impreza Rear Strut Noise Production Change

The Impreza rear strut was modified in production to eliminate a thumping noise when hitting bumps in the road. The production change was made beginning with February 1, 1993, and later with lot number NA19 and later. The lot number is located just under the lower spring saddle on the strut housing.

Lot number explanation: N=93 (year) A=January (month) 19=day of month.

In the lot number, the year designation runs backwards in the alphabet:
N=93 M=94 L=95, etc.
