Better get it out, soon you will be throwing sparks and smoking.
Did my left front a couple months ago, did the ujoint and ball joints also, about $485 total, Napa 4 wheel abs hub was $269. I was up to portland hauling a pw back down, and started to feel the same 70mph shimmy I felt when the left one went out. So as I drive up along I-5 I call all the napa along the way trying to find one. Found one in Salem, bought it and the ball joints and ujoint. Just waiting for it to get worse, or maybe I'm lazy, I only drive 13 miles to work. 135k on the drivers side one, about 140k on the right side one so far.
