Right Rear... New Noise

I just started hearing a "thumping" noise from the right rear my XJ (87 4.0 Wagoneer) when making a hard left turn. I don't hear it while turning right or goig straight.
Wheel bearing? Or am I looking at something difficult? Any ideas?

Sounds like either a busted shock mount, or your rear sway bar may be loose. But check your springs and shackles and axel U-bolts to be safe.

Really grab and shake those things to check for any looseness.

Hope this helps
