All Spicer Carrier Type axles are identified with a manufacturing date (1) and Bill of Material number (2) stamped on the right or left hand tube on driving axles. The Bill of Material number may also be found on the carrier in some models as shown in illustration (2A). For independent front suspension (IFS) axles, the B/M number may be located at one of three locations: 1). A vertically positioned tag near the center of the right hand side support arm, 2) stamped into the left hand side support arm (opposite end of the camber adjuster), or 3) stamped into the "nose end" of the axle carrier. The location of the information will depend on the manufacturing date of the axle.

The axle model number will be cast into one of the webs as shown (3), or it can be on the nose.

Each axle contains a gear ratio tag (4), and if the axle is equipped with a limited slip differential, it will have a tag specifying the type of limited slip lubricant to be used (5).

Refer to the appropriate model number section for parts identification and a breakdown of the Bill of Material.

We no longer list BOM numbers here. There's just too many.

Looking Up BOM (Bill of Material) Numbers:

You can look them up in these documents:

1967-1978 Dana Axles - Look up BOM numbers under specific axles

1978-1998 Dana Axles - BOM numbers start on pdf page #9

If you can't find the number you're trying to look up, you can go to the Dana site HERE and enter it.

Looking at the axle sticker, we see on the top left Dana P/N 610659-1. If we go to the Dana Part Identification Page, we see that this axle is from a Ford F250/350 SRW (Single Rear Wheel - Non-Dually) 4x4. The results can be seen HERE.

The number on the top left of this sticker in 610366-8. Using the same method to look up this number, we find that it is a Dana 35 from a Ford Explorer.

Axle Tags & Door Stickers:

You can also identify axles by their axle tags and the sticker in the door jamb of the vehicle it came from. Click HERE for more details.
