Two models of the Chassis Ear. The original one costs $199.99 from the guys on the tool trucks like Mac, Matco, and Snapon. You can find the same thing on Amazon. Com for less than 70 bucks. The newer model lists for 100 bucks more. Four of the six microphones are wireless so you can attach them to rotating parts, and you don't have to carefully route wires to inside the vehicle.
If any weight was placed on the new bearings before the axle nuts were torqued to spec. That would damage them and make them noisy. People often set the vehicle down on the tire to hold the axle from turning when they tighten those nuts and that will do it. I stick a screwdriver in the vent slots of the rotor to hold the shaft while I tighten the nuts. The torque spec. Is critical too. Over and under-tightening the nuts will ruin the bearings.
When does that popping occur and how often? Once per wheel revolution? Over bumps? When turning the steering to one side or when returning to center?
