Axle Information

Your Mustang will be equipped with a Vehicle certification label on the driver’s side door jam. This label will show your axle code under the “AX” slot.

All axles for these years are integral carrier type axles, however they will come in two sizes; a 7.5 inch and an 8.8 inch. There is a small metal tag bolted to the axle on the bottom line of the tag will be 3 pieces of information. The first piece will be the ratio, the second piece will tell you the ring gear size (7.5 or 8.8) and the last piece of information will be the build date (year, month & day).
