Hey there guys, just picked up a 9er with 162k.

Ive already had the transfer case resealed, and the rear diff rebuilt.

However, I have a front diff whine, and would love for someone to confirm that indeed its a viscous coupler issue or something else.
If someone is in Portland, and can let me know what it is, or wants to wrench I'd love the assistance and meetup with a fellow niner.
