Suspension arm refresh query

On the front axle plan to change both arms on each side. The smaller arms are pretty cheap, so seem like a no brainer.

On the rear, there's three arms a side, so I'm wondering whether I might get away with not changing all of the. I have some knocking at the rear, I think. Have already done the rear drop links, didn't help.

Here's the diagram:



It's the forked arm and the smaller arm number 17 I'm wondering about. Are either or both of these likely knock candidates? Maybe one of them is unlikely to cause knocks and I can skip it?

I'm going to have a look under the car and give things a shake. But that doesn't always give a clear indication.

Thoughts, anyone?

#8 is the top suspect for noises, #17 controls rear toe setting which is what wears the tires irregularly when worn. Alignment must be done after disconnecting any of these parts so if your car has more than70,K miles do everything now & save a little on the labor & 1 alignment charge instead of 2.
