Transfer Case
67
Front and rear differentials, solid axle assemblies, transfer cases, power transfer units, AWD couplings and actuators for pickups, SUVs and AWD crossovers.
Whining at highway speed, clunks when turning or 4WD that will not engage are common reasons to replace a drivetrain unit. Always match the axle ratio and the transfer case model code so the front and rear axles turn at the same speed.
