1999-2004 Mustang Cobra IRS Rear Axle Bearing & Seal Kit

Whether you are replacing your axles or servicing the rear differential, it's always a great idea to replace worn axle bearings and seals with brand new ones from Ford Performance. The IRS axle bearings and seals are located on the Cobra IRS differential housing where your halfshafts install into the differential. When axle bearings and seals wear out, you can experience axle play in the axle shafts as well as fluid leaks. This kit features new high-quality axle bearings, durable axle seals, and axle nuts to complete your installation. This kit is the perfect choice when swapping rear gear ratios or installing new halfshafts in your 1999-2004 Mustang Cobra as it's cheap insurance against possible axle failure in the future! 


Differential Fluid Note

 A small amount of fluid loss will be expected during installation, so this would be an excellent time to change it out with this Royal Purple max gear oil and friction modifier kit.
