Re: Eaton HO72 rear axle

More part #'s :
Some may be available, Some may not be.
Some of this crosses over into 1973 and up.
It appears that GM continued using the same axle spindle dimensions.
The drums look to be obsolete now.

Axle Spindle nut (4):
Dorman 615-130
2"-16 thread

Axle Spindle washer (2) :
Dorman 618-048
2" X 2-5/8"
(on occasion, these may need to be clearanced on the inside diameter where it passes over the spindle. They are tight or do not pass over the threads. I had to de-burr the 2 Dorman washers that I used)


Axle spindle LOCK retainer (2) :
Dorman 618-049
2" X 2-9/16"

Axle Shaft Flange Gasket
(O-Ring or Seal)
Fel-Pro 55350

Hub bearings
Timken 388A (large bearing)
Timken 382 (large bearing race)
Timken 368S (small bearing)
Timken 362 (small bearing race)

Rear Hub Seal :
National PM2081
National 710568 (Escalade)
The Escalade seal above resolves the 2081 from leaking due to wear grooves that occur on the landing area for the housing.


Differential cover gasket :
Clevite P-39130
Mahle P-39130
Victor (Reinz) P-39130
JEGS 695-P39130
Fel-Pro RDS 5088

Drop Out Carrier gasket :
Fel-Pro RDS 5090

Pinion Seal :
Yukon YMS411330N
Part # : 807-YMS411330N (JEGS)

Pinion Shims :
Yukon SK20100
Part # : 807-SK20100 (JEGS)

Yukon Differential Bearing Kit :
Yukon BKGMHO72B
Part # : 807-BKGMHO72B (JEGS)
B - denotes "Load-Bolt"

12" Brake shoes:
Wagner Perfect Stop # PSS248DR
