2004 Mustang Rear Axle and Rear End

Rear Axle

Depending on which model of car you drive, your 2004 Mustang’s rear axle is either a solid axle design or uses independent rear suspension. V6 and GT cars get the reliable solid unit, while the 2004 Mustang Cobra receives a high-performance independent rear suspension arrangement. Both variations on the 2004 Mustang rear end have advantages and drawbacks, and for this reason the aftermarket has done a great job of providing the parts needed for those who want to make the switch from one arrangement to the other and vice versa. The team at CJ Pony Parts has selected the best 2004 Mustang rear end parts, making it easy for you to upgrade, maintain or entirely replace your 2004 Mustang’s rear axle or differential.

2004 Rear Axle

Few parts on your car play a more important role in putting power down than the rear end. If your 2004 Mustang’s rear axle or rear end is damaged, you will not be able to deliver power effectively during cornering and acceleration, and you might also notice a decrease in shift quality.

It’s a good idea to check your rear end hardware and bushings before you make the investment of replacing the entire unit. CJ Pony Parts has complete sets of 2004 Mustang rear end hardware and bushings available at low prices. You might be surprised by how much a new bushing set does to reduce drivetrain slop.

If you are planning on upgrading your car’s engine to deliver more horsepower, an upgrade to its rear end and rear axle hardware is a great investment to ensure you won’t be experiencing axle hop and transmission damage. You can also improve performance by installing new gearing. Take a look at the variety of ring and pinion sets available from CJ Pony Parts. Gears with a lower ratio (for example, 3.15:1) will deliver taller gearing and a higher top speed. Shorter gears (for example 4.10:1) will improve acceleration but lower top speed.

For maximum grip, upgrade your 2004 Mustang’s rear end with a locking or limited-slip differential. CJ Pony Parts has a number of differential options available from Ford Racing to fit both solid axle and independent rear suspension cars.

Already running an upgraded differential? CJ Pony Parts carries full rebuild kits for the popular Ford Racing line of components. Don’t take the risk of letting your expensive investment fail — the small amount of time and labor involved in maintaining your differential is a far cry from the cost of replacing the entire unit!
