Pinion bearing...
Recently my wk (4.7, 2005) has developed a hum in the front end, normally around 20-40 mph and then it goes away. I was told maybe a pinion bearing..... any thoughts, or ways to diagnose this.

Re: Pinion bearing...
is it a little more high pitched, and not so much goes away just gets high enough that it kinda sounds like it goes away?

I wouldn't say its high piched, its like a low hum that seems to go away over 40-45 mph
