Description

This axle kit fits 1999 to 2004 Ford Mustang models equipped with ABS and either the 7.5 or 8.8-inch rear differentials. It is specifically engineered for vehicles with 28-spline axle shafts and a 5 x 4.5-inch bolt pattern within this range. The kit is a direct replacement, requiring no modifications to vehicle components, and is intended for experienced service professionals or knowledgeable enthusiasts, with an approximate installation time of 2 hours and a light to moderate mechanical skill requirement. The included components consist of the rear axle, wheel bearing, seal, studs, and lug nuts.
