Differential Mount Bar Lower Serrated Washer, 70-4/71 240Z
|Quantity in Basket:none|
Discontinued by Nissan. We recommend 23-4139.
This washer has unfortunately been discontinued by Nissan. If your washer has worn out, we strongly recommend using our urethane kit instead (see 23-4139 in Related Items below), since this bushing is required to use the factory type bushings. Factory bushings will not properly insulate the diff mount bar from the body of the car, leading to significant vibration and improper diff alignment. Most used replacements for these washers are already worn out and unusable.
This is the rubber and metal "washer" that fits under the factory differential bar bushing. It has deep rubber serrations where it meets the bushing. Sold individually, two required per car.
The later 74-78 washer (10-2274 in Related Items below) can be used in place of this piece.
