Clunking noise in tranny area

Clunking noise in tranny area
Hey guys I welded my diff as well as a solid front diff mount with a preloaded pinion snubber, poly tranny mounts and when I turn while the inner wheel skips,I get clunking noise in the tranny area when I'm in neutral, But goes away if i turn while in gear. I remember replacing my tranny mounts and the bushing on the tranny crossmember fell out. So my next step was to look into the driveshaft u-joints and see if there is any play or purchase a new crossmember. Can you guys help me to see what other things can cause this clunk? Thanks!

My guess would be the front diff mount slapping the body of the car.
Or it could be a (way less violent) jerk on the driveshaft.. I'm thinking that as the tire skips, the diff quickly jerks the drive shaft, making it bounce back and fourth(freely since it's in neutral).. I have a 1.5 way diff + a 6-puck clutch, and *rarely* when I press in the clutch, and pull it out of gear, while moving slowly, the diff will lock up, and bounce my driveshaft back and fourth.. It makes a funny clunking noise, and is pretty harmless since the weight of the drive shaft alone will not likely damage u-joints.

I really don't think there needs to be much play for it to make a noise. Also, the amount of force you can put into it is faaar faaaaaar less then a 2,800 lb. Car can while in gear, so you might not be feeling all the play..
maybe look above the diff/diff mount area for fresh scars/marks in the the body. It could just be banging against it. My buddy has solid diff mounts, and his clanks and bangs when he shifts.. Like 75% of the time hahaha

Well the pinion snubber is preloaded so there's pressure on it pushing onto the subframe so I'm almost positive it's not that and the noise is near the armrest. You think a broken crossmember could be the issue? I kind of feel iffy spending 100 on a new one cause it seems like it wouldn't make a difference cause the two mounts on the tranny should be doing the job but than again they wouldn't put the bushing on the crossmember for no reason
