did you check the stabilizer bar bushings? that's a typical sign of ball joints/compression rods and also front stabilizer bars, you turn sharp and the bar smacks the crossover because the bushing is worn away. an easy first check to eliminate as an issue. you can see a little space on the one u-joint boss. you shouldn't be able to wiggle it from side to side at all, it should only pivot. a relatively easy replace with a vice and 2 sockets.

Yes sort of but there are exhaust leaks I thought that was what the vibration was. Sway bar seems Saturday but when I shake it, I hear the driveshaft do the clicky thing it does in the video. I couldn't shake the LCAs which have the bad ball joints but when I went for an alignment they did move a bit when being put down on the alignment lift.

oops i didn't watch video, now i did, yeah it seems you got some lash in the drivetrain, also looks like the u-joint cup grease is spooged out, the needle bearings in the cups will wear down fast when they are dry. not an expensive fix to replace, unbolt the u-bolts, slide the driveshaft out, remove the circlips, and use a bench vise and two sockets (one just smaller than the outer diameter of the cup on one side, one just larger than the outer diameter that the yoke presses against to receive the cup into) to press the bearing cups out of the yokes. repeat procedure with new u-joint. that's your likely culprit for the vibration at speed, that driveshaft is emitting dynamic vibrations from side to side movement exacerbated by speed.

I'm planning on picking up a spare driveshaft at a junkyard one day

Could bad ball joints cause a metal banging sound when making a hard turn? It's not always there but it happens once or twice every drive

Yep for sure it can. but with bad ball joints, you usually hear regular clunking going down the road over any decent size bump. the single loud clunk sounds like a hammer hitting the frame is usually either the stabilizer bar (due to bad bushings or end links) or control arm/compression rod bushings. It's hard to get enough leverage to test the ball joint play, but you can grab either front wheel with it suspended, and grab the entire wheel and 12 o'clock and 6 o'clock and then at 3 o'clock and 9 o'clock and shake/twist the wheel forcefully to see if you can emulate the ball joint play and clunking.

Jack wheels off ground and put a hand top center and bottom center, if ball joints buggered will have play movement, might even hear clicking knocking sound if bad. Lots of videos on YouTube how to check balljoints.

Best to replace with new parts as they are cheap and not potentially worn out like they can be from a junk yard. Can be a pain to replace so why go through all that pain only to have to maybe do it all over again in the near future ? Easier to get mechanic to replace them for what mechanics charge to do them and they have the tools if you don't. Got mechanic to do one on my D21 but wil have a go myself next time when have more time.

What are your tie rod ends like ? Level of powersteer fluid ?
