Thunk when turning right Topic is solved

Hey all, great forums here!
It has been brough to my attention that my sister's 240 sedan (not sure what year, early 90's) has developed a very concerning thump when turning to the right. I drove it and very much so their is a major thump when turning to the right and again when you bring it back to center. It does seem to matter how much you turn it, it'll do it. I assume something is very much moving when making the right hand turn when it should not. So I went underneath and check the status of the tie rods, checked torque on: steering rack, tie rod end, ball joint, control arm, anti swaybar mounts and the swaybar link. All were good and tight. So what am I missing here? What other parts should I check for movement (eeuroparts.com does have a scematic for this car)? Could this possibly be a worn out strut mount?

Thanks for all your help!

Jack it up, leaving the wheel on, and try and find which direction it's loose.
It could still be a vareity of things, but finding out whether it clunks fore-aft or in-out would help a fair bit in eliminating most of the suspension.
Both control arm bushings are in decent condition, correct?

It could be a strut mount, BTDT.

Went to local volvo parts and got some bushings but they did not
look like the originals. This can be a concern. Anyone run into this?

What specifically are you worried about? Fitment, ride quality, or endurance?
If they're Scantech, it's quite possible that they're made of an inferior rubber... Not a problem with ride qualiy, but a problem with lasting, yes.
How exactly do they look different? Are the voids in the rubber larger? Is the rubber of a different color, or hardness?

I myself am kind of doubtful of it being the mount, from my experience they kinda groan for a while (my current car is doing that now). Mounts for control arm look good. When you say jack it up and see if its fore-aft thing do you mean pull the wheel towards the rear of the car? And for the in-out just try to shimmy it back and forth? I'll try that, but unfortunately the weather is crap.

A few other things I forgot to mention. Its only when the car is in motion (greater than 5 mph). And when it happens it doesn't feel like the car suddenly jerks to the right, makes the turn as if nothing is happening.

I mean grab the tire at 3 and 9 o clock, rock back and forth, then at 12 and 6 o clock, and rock from those points.
Depending on where it rocks, you can rule out the suspension, based upon where the play would show up.
