SIMILAR TO THE STANDARD 8738032 SEAL AND RETAINER ASSEMBLY, THIS WOBBLE SEAL EQUIPPED UNIT WILL DO THE SAME JOB, BUT SEAL BETTER IF YOU HAVE WEAR IN YOUR FRONT AXLE. 

EVERYTHING IN THE FRONT AXLE FROM THE DRIVE FLANGE CAP TO THE CARRIER IN THE DIFFERENTIAL HAS SOMETHING TO DO WITH CENTERING YOUR AXLE SHAFT TO KEEP THE AXLE OIL SEAL WORKING CORRECTLY. THIS WOBBLE SEAL ASSEMBLY WILL COMPENSATE FOR WORN PARTS AND MISALIGNMENT. 

PLEASE NOTE, THIS RETAINER ONLY ACCEPTS THE WOBBLE SEAL AND WILL NOT ACCEPT THE STANDARD 7521789 AXLE OIL SEAL.
