It can also be the ARB bushes but that's usually accompanied with knocking noises.
Almost certainly the upper arm bushes. Not Nylon btw, but metal inserts in a rubber outer, fitted in the "shell" on the arm....you can push out the metal inners with the arm off the car, regrease and refit them but you're probably in need of new arms at that age tbh. Especially if it's the 2.4 (your "member car" doesn't state which one!).
Thing is, upper arms USUALLY squeak when you bounce the car if it's them......USUALLY......
TRy and identify the "height" of the sound. If it seems to come from behind the dash then it's the upper arms. If it's below your feet, ARB is likely.
