Output shaft seals and care
Output shaft seals keep fluid inside the transfer case where the shafts exit the housing. On a Quadra-Trac unit, a worn seal usually shows up as fluid around the shaft end or the yoke area, and it tends to get worse over time. Replacing the seals while the case is open is a sensible step if the shafts show any play.
Seal lips can be damaged during removal, so use the correct tool and avoid scratching the bore. Check the shaft surfaces for grooves before installing a new seal, since a grooved shaft wears a new seal quickly. Keep track of which seal goes to which position, because front and rear shaft seals can differ.
- Inspect shaft surfaces for grooves
- Protect the bore during removal
- Note which seal fits each position
