i was looking at right cv boot and it is tore all the way around.it has slung all the grease out.will it hurt to drive in the short term? will i have to replace the axle or just the boot? thanks very much volvodoc!

04 xc 90has a vibration when accelerating.it doesnt do it while coasting so i dont think it is the tires.thanks for any advice.it has about 100000 miles on it.
