Hi. i need to change Wheel Bearing on all 4 wheels on my 2WD 1995 Suburban 1500

have called to different shops that only sell parts for cars made in america.
but they say different thing.
One is saying that it is only 1 bearing on each wheel. and other say that it have a inner and outer Wheel bearing.

so who have it correct?

 

Fronts will have an inner and outer, rear only one per side and you will have to pull the axle to remove them using a puller on a slide hammer.
