Please Confirm - Large Axle Bearing?

[NJBronk]

Ok, I've read the posts here and looked at the pictures on the Wild Horses page:

I'm pretty sure I have a large axle bearing due to the bulge, but then I'm second guessing whether that's really a bulge?

Before I go ordering parts, can someone confirm this looks like a large axle bearing?



Thanks!

Best way is to find the stamp on the back side of the brake housing. Scrap it clean, then reference the charts attached. Nearly impossible to read on the vehicle, so take a pic and blow it up. Good luck

Bendix 319130L or 317363L = '66-'75 big bearing/11"x1 3/4" brake , driver side
Bendix 319130R or 317364R = '66-'75 big bearing/11"x1 3/4" brake , pass side
Wagner FF55264 or L55264 = '66-'75 small bearing, 10" brake, driver side
Wagner FF55265 or L55265 = '66-'75 small bearing, 10" brake, pass side
Bendix 80174L = '74-'75 big bearing/10" brake, driver side
Bendix 80175R = '74-'75 big bearing/10" brake, pass side
Bendix 3203097L = '76-'77 big bearing/11"x2 1/4" brake, driver side
Bendix 3203098R = '76-'77 big bearing/11"x2 1/4" brake, pass side

If you have 11" rear brakes you have big bearings. 10" rear brakes can go either way.

I was able to see "8017". I tried using a brillo pad and that didn't seem to do anything and then a gasket scraper seemed to take the numbers right off so I quickly stopped... But that was enough to determine big bearing! Thanks!

It appears to be a large bearing.
Small bearing the axle tube would run although way to the end.

Yeah, it’s a big bearing.

Yup, large bearing, 10" drum. There is a "4" or "5" after the 8017 depending on left or right side.
