I assume you're referring to the replacement of the 2 cables which attach to the rr calipers. You can jack on the forward rear control arms, but NOT THE toe control arms. Or find the strong point in the rear chassis IIRC close to where the longitudinal suspension arm connects to the chassis.

Yes it's necessary to drop the exhaust to gain access to the junction point where the 2 cables connect to the "Y". You'll also need a big wrench to lever the arm where the cable attaches to the caliper. A helper works too! BTW-the boots on the cable ends don't do much. I had a repeat of this problem with the new & improved cables. However, since I added my own extra helper spring for the cables I've had no repeat on this problem.

As for your rear suspension "clunk" it's usually the rear sway bar making contact with the subframe. Is your car lowered or does it have an aftermarket rr sway bar? If the answer is yes to either, that will be a mitigating factor. If not, check the rr end links and/or sway bar bushings-they fail regularly.
