Steer Axle
Dana Steer Axle products are identified with serial tags, tags that vary generation to generation. Below are illustrations showing the common locations of the Steer Axle tags and typical information data shown on them. Thru the generations, Dana's numerous assembly part numbers and model designations vary. The Dana ecommerce site will populate only newer generation of assemblies made after the year 2000. If you have older serial numbers contact Dana Help Desk.

How To Identify A Spicer Axle
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 manu- facturing 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.

How To Change Gear Ratios
To increase or decrease a gear ratio, there are certain steps that must be taken. The differential case depends upon the ratio desired. For each axle model, there is a high-ratio and a low-ratio case as illustrated below:

Example - If you have a model 44 Rear Axle with a 3.54 ratio and wish to change to a 3.73 ratio, you change only the ring gear and pinion assembly. If you change the ratio to a 4.09, you must change to a high-ratio case in addition to changing the ring gear and pinion. The application section will show you what case to use. When the vehicle is equipped with both front and rear driving axles, the gear ratios must be the same in both axles. The drive gear screws are self-locking and must be replaced with new screws each time that they are removed.

Application Policy
Capability ratings, features and specifications vary depending upon the model type of application and the type of service. Application approval must be obtained from Spicer Off-Highway Driveshaft Engineering. We reserve the right to change or modify our product specifications, configurations or dimensions at any time without notice.
Part Number Determination
Included in this catalog are standard Spicer Off-Highway assembly part numbers for tube type driveshafts. Each assembly has its own individual simple formula for calculating the proper tube length of the collapsed assembly.
*10-Series
The four digits to the right of the dash on all Spicer driveshaft parts are used to identify the length of the tube used in the shaft. The first two digits indicate the length in whole numbers of inches while the last two digits indicate the fractions of inches in 32 nds. That is to say a tube length of 9 1/2 inches would be expressed as "-0916" (nine and 16/32 inches).

*SPL-Series
The four digits to the right of the dash on Spicer Life Series driveshaft parts are used to identify the length of the tube used in the shaft. The four digits indicate the length in millimeters followed by the letter "M". That is to say a tube length of 923mm would be expressed as "-0923M".
*Note: Shaft length is always expressed fully collapsed.
