I would replace the upper and lower engine torque rods and the right mount below the crankshaft pulley. I recently replaced all 3 on my 1999 V70R at 80,000 miles. The right mount looked fine while on the car, once removed, there was a huge crack on the under side of it. The new one raised the right side of the engine up by an inch or so. The upper torque rod bushing had cracks in it, the lower torque rod bushing was soft, easily moved by hand. The new one was noticibly stiffer. The hydraulic motor mount that is at the front of the car, left side of engine, was not leaking any fluid, so I did not replace it.
