7-1/4" axle 1973 10 inch brake wheel bearing part number?

[timk225]

I'm buying parts for spring time work on my 1973 Duster, and one thing I am having trouble with is replacement rear wheel bearings. They haven't made noise so far, but they are 52 years old, and I plan to drive the car more this year.

The 7-1/4" axle has the 10 inch brakes and big bolt pattern, so the 1.399" axles should be in there. I need a set of bearings and the retainer collars. I've been looking at various websites and ebay, and the ones I find are either wrong or the older smaller bearing size.

I wasn't planning on pulling the axles, but I'm adding 1-3/16" (30 mm, but this is AMERICA!!!) wheel spacers so the rear track doesn't look so stupid, and that requires longer wheel studs, and that requires pulling the axle shafts out. I already got new oil seals, and I figure if I'm going this far, might as well change the old bearings too.

Rear wheel bearing numbers for the 1973 Duster with 7-¼" rear axle and 10" drum brakes are listed in the following table:

Brand	Part Number	Notes
Chrysler	2808272, 3420091
ABC	RWC35YYR
BCA	RWC-35-YYR	(now part of NTN)
CR (Chicago Rawhide)	RWC35YYR	(now part of SKF)
Centric	411.63000
L&S	RWC35YYR	Or RWC35R
National	RWC35YYR
Precision Seals & Bearings	RWC35YYR
PTC	RWC35YYR
Sealed Power	B-RWC35R
SKF	RWC35YYR	Or RW32, RW32R, RWC35VSP85, RWC35VSP35
Timken	RWC35YYR
WJB	WBRWC35YYR

Bearings include (or should include) the collar.

Note that most numbers are variations of the same base number. Some listings may include extra dashes, example: RWC35-YYR RWC-35-YYR

These bearings fit the following applications:

• 1973 - 1976 A-body 7-¼” axle with 10" drum brakes
• 1976 - 1980 F-body 7-¼” axle, 10" drum brakes
• 1977 - mid-1982 M-body 7-¼” axle, 10" drum brakes
• 1981 - mid-1982 J-body 7-¼” axle, 10" drum brakes
• 1970 - 1972 E-body 7-¼” axle, 10" drum brakes
• 1969 - early 1971 B-body 8-¼” axle, 10" drum brakes

The 7-¼" rear axle in the 1960 - 1972 A-body and the 1973 - 1976 A-body with 9" drum brakes is a different smaller bearing. Mid-1982 and later 7-¼" rear axles have the later 8-1/4" axle tube/ends with a different bearing.
