Dreaded clunk when turning

Great info that's so much. I ordered the Motive kit on Amazon for $80. Now in the manual it talks about race and bearings on the axle shafts. Are those able to be reused or am I going to need to replace all that as well? I am hoping all I do is rent the axle puller, pop out the shafts, replace the spiders, then push it all back in?
