OK, I'll go against the grain somewhat. Definitely torque rods, they wear out and installing polys you can do yourself (sans press). I am not sure the verdict is in on longevity of poly TABs and the rest of the bushings are so durable that it is kind of a waste to overdo them. I have never seen a worn out front bushing, panhard bush, front rear TAB (the little one) on my cars. It is TABs and torqs that make the big difference when you renew, poly is for those who get easily carried away, I think. I'd be for it in TABs if they are durable but I am not impressed with the soft and squishy poly radius rods bushings on 7-series cars. New bushings are a real nice thing, poly bushings have a lot of placebo factor, like oied foaml air filters in my opinion.
