They should have everything you need at Autozone, but ONLY buy the Timken brand bearings and races, none of that value-crap brand. D44's have a spindle difference between years, so unless you know for sure if its big bearing or small bearing, I would take the old bearings down there with you as the "parts guys" there dont know anything
you will need the following parts:
Outer Bearing
Outer Race
Inner Race
Inner Bearing
Wheel Seal
Outer's usually come as a matched set, but inners could be either a set or seperate. Should be about $35 per side
