Best for owners doing their own front hub or MFWD seal repair on this model.
Appears to be a working shop/technician channel documenting real repair jobs, not a dealer sales pitch or general review.
Remove the wheel and hub, press out the bearing with a shop press, replace the two-piece seal, clean parts, then press in the new bearing and reinstall the snap ring and lock ring.
Yes, the technician used a flat piece of steel to press the seal in and needle nose pliers to set the lock ring instead of the special tool.
The two-piece seal had debris inside it, likely from bush hogging, which may have contributed to the leak around the bevel gear pivot.
