Hello,
I've been looking around all morning for a damn steering knuckle for my '97 5.2L extended 4x4 and I've had no luck. Junkyards are closed today and any auto parts store I talk to say's that they don't sell it to begin with. I've checked rock auto for the part and they don't have it either. Is there somewhere out there that sell's this part or am I SOL?

 

I suspect the only place you are going to find it, is on the used market. Seen this before with the daks and durangos....

 

If you can wait a few days, Ebay usually will have what you need. The local stores have jacked prices up so much in the last couple of years, I've started getting parts there.
