Weird thumping/bumping noise passenger side

[RatedR]

1991 Fastback LE160XXX miles

I noticed that at slower speeds, the car has a bumping/thumping noise/sensation coming from the passenger side. I'm not entirely sure if its the front or the back, but after work today, i took off the rear tire (brand new by the way, bought the set in Dec 2003...I think) and placed my old steelies in. The bumping was still there, so i thought it would be the front and I took off the front and replaced that with another steelie (now both passenger sides have steelies) but the problem was still there. Also, I noticed that when making a turn under acceleration (right turns I think), the thumping gets worse. I was wondering if there's any other suspension piece I should look at. Would it be my open-Diff? Any help/sugg. would be nice, thanks guys!

CV joints?

i'm not sure, but my wife and i diagnosed the noise to be originating from the front. Is it possible for the TC rods to produce this problem?

after checking again, I think now its coming from the passenger rear. Would it be possible that my diff could be doing this? I havent changed that oil in there cause when I bought it I found out that it wasnt a VLSD. So I thought I'd just run it till it breaks and replace it with an LSD. Or would it be more likely my axle?
