Where does the axle come together on a Mustang?

Where does the axle come together on a Mustang?

This is the heavy iron casting where everything comes together in the center of the axle. It holds the ring and pinion gears in alignment and is removeable as a unit allowing fairly speedy ratio changes if you have a selection of third members handy.

How big are the bolts on a Ford Mustang rear axle?

My housing also has the “large” housing ends with 1/2″ bolts at 4 3/16″ spacing. Some modifications I plan adding are a large ‘bung’ for adding oil and to inspect the ring gear through, epoxying a strong magnet in the bottom to catch any metal chips and upgrading the vent to lessen chance of pressure building up and causing an oil leak.

What’s the difference between 28 and 31 spline rear axles?

Visually, the car axles can be identified as 28-spline when the visible outboard center is a rounded rectangular ‘dish’ whereas the 31-spline versions have three drilled dimples. A full spool is used in place of the differential that normally allows left and right wheels to turn at different speeds when turning.

How big is the rear axle on a 1964 Mustang?

You have to use a spanner. The location of the spring perches on the 1964-73 Mustangs is the same for all models, the extra width is all outboard of the spring perches. This means (for example) that a 70 mustang housing will fit into a 66 model, but will be 1 inch wider on each side.

What kind of rear axle does a Mustang II have?

The Mustang II utilizes two different style rear axles. The first axle is used on 4cyl and some 6cyl cars and is a 6 3/4″ ring gear integral carrier axle. The second is used on some 6cyl and all 8cyl cars and is an 8″ ring gear removable carrier axle. The two axles are easy to tell apart.

Where do you find the Axle code on a Mustang?

The following axle identification is based on the axle tag located on the axle, if you have the code from the door tag (Certification label) you can look up your axle in our code reference section . The rear axle assembly is an integral-type housing, hypoid design, with the centerline of the pinion set below the centerline of the ring gear.

How big is the carrier axle on a Mustang?

The second is used on some 6cyl and all 8cyl cars and is an 8″ ring gear removable carrier axle. The two axles are easy to tell apart. Looking at the axle from the rear of the car, if the center section has a cover with bolts around the circumference, it is the 6 3/4″ axle. If there are no visible bolts from the rear, it is an 8″ axle.

Where are the wheel bearings located on a Mustang?

Ball bearing assemblies (rear wheel bearings) are pressed onto the outer ends of the axle shafts and set in the outer ends of the axle housing. Certain vehicles are equipped with tapered roller bearings, with which a different type of oil seal is used. These bearings support the semi-floating axle shafts at the outer ends.
