The pinion seals must be the same as CRD92/93 carriers had which were used on R-models and many newer Macks. Try checking Stemco web site. They have online catalog for hub and pinion seals with sizes and discription.

From what I have in my copybook you seals should be :

Front input Mack 88AX458 Stemco 429-0002 4.5x3.5"

Front output 88AX456 429-0008 3.537x2.751

Rear input 88AX457 429-0009 3.996x2.751

If you were saying your truck is B61 I'd say go with the numbers I posted. But you B81SX might have heavier carriers . So better slick under the chassis with a caliper and relate the sizes.

A B81 could have the 50,000 rears, takes a different carrier, different seals maybe.    terry:MackLogo:
