Usually it would be on the back side of the brake rotor.

 

I jus replaced the lower ball joint in my 04 1500. I used a pulley puller and a impact to press the old one out . And a collar o machined from someone shed 80 pipe and another bearing puller and an impact to press the new one in. ( red neck I know, but it worked) but my problem is it still didn't kill the clicking and crackling and clunking coming from the front left. New CV axle and trod ends. With no relief. If I don't figure it out soon my wife is gonna make me take it to a much. ( ultimate defeate)

 

I trust eBay. Just make sure you cross ref it with rock auto.com parts and number then double check em with you local auto zone, Napa or advanced auto.
