Well... after seeing two mechanics... the verdict is in:
Both of the axles need to be replaced on my Subaru Forrester.
Apparently the U-joints went out and even though I've asked about the shimmy when I turn twice in the last six months and even had work done on the wheel in August when my clutch took a dive, no one thought to look at my axles / U-joints until now.
So... looks like I'll be putting another $600 - 700+ dollars into my "paid for" car. At more than 167,000 miles there are bound to be things crapping out... I'm just not sure I have the patience for it... I think it is time to go through the budget and see how much we've spent fixing it this year to see if it is actually worth it.
