Count the splines on an axle shaft before ordering because a different spline count will not engage the supplied carrier.\u003c\/p\u003e\n\u003cstrong\u003eWhy order a kit instead of separate parts?\u003c\/strong\u003e\n\u003cp\u003eThe kit keeps the gear set, carrier, bearings and small parts matched under one number, which avoids mismatched shims or a missing seal stopping the build.\u003c\/p\u003e\n\u003cstrong\u003eDoes a re gear need a break in period?\u003c\/strong\u003e\n\u003cp\u003eYes. New gears need a gentle initial period with varied speeds and no towing, followed by a fluid change, so the tooth surfaces bed in evenly.\u003c\/p\u003e\n\u003cstrong\u003eIs special equipment needed to install it?\u003c\/strong\u003e\n\u003cp\u003eYes.
