Genuine BMW part 52 53 1 451 393: Expanding nut. The number stamped on the part is 52531451393; BMW's catalog files it under the short number 1451393. You will find it on our Interior Body shelf, under Seat bench. It supersedes the older number 1453508, so a part carrying that number is the same part.
It fits the E36 sedan, coupe and compact (318i, 320i, 325i and 328i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.
BMW draws it on 43 diagrams, among them Front Axle Support/Wishbone (31_0219) and Front Axle Support/Wishbone (31_0242). It weighs about 1 g (under 0.1 lb). It also comes in BMW kits Mounting parts, case holder (7682331) and Retrofit kit, heat resistant plate (9415409).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
