unique to many RWD vehicles is the cleaning, inspection, and repack of the front wheel bearings of 1982 to 88 200SX and the 1989 to 92 240SX at every 30k mi or 24 months, although the latter came with a one-piece front wheel bearing and did not require any form of attention. To clean and repack the front wheel bearings on the 200SX, the bearings have to be withdrawn from the wheel hub; It is imperative that the bearings move with a minimum of play before being removed. However, front wheel driven cars such as the Stanza have dissimilar front wheel bearings and these front wheel bearings coupled with the front hub needs bearing assembly servicing, and has no necessary routine servicing. Rear wheel bearings for both FWD and RW are similar, and for the Stanza, it is recommended to clean, inspect, and repack the rear wheel bearings at an interval of 60,000 miles or 48 months Which makes it necessary to pull the bearings from the wheel hub for servicing.
