Dealer wants to remove the axle to replace the timing belt. Does that sound right?

The CV axle does not need to be removed. There is a plastic access cover to the crank pulley - which can be fold up. I'd suggest to replace ALL THE TIMING COMPONENTS, not only the belt. The tensioner, idler pulley, water pump front crank, cam and rear cam seals just as important as the belt. The bad thing is, for the seal replacement the crank and the cams has to be locked by a special tools into the service position, which will kind of doubles the labor time, however that would be the correct timing service.
