My 02 burb has been making the moaning noise for sometime now in the front. I replaced both hub assemblies. The moan did decrease a little but, still noticeable. I did notice I can move the left axle flange up and down. I'm wondering if I replace the bearing and the seal will the noise go away or take my chances with buying one from a salvage yard. Everyone's opinion will be accepted. Thanks..
