The statements above from the service manual sound more like accessing the fuel pump module!
Some of the instructions in the Viper service manual are rather amusing, however. They have you removing the front belly pan to drain coolant from the radiator, which is totally unnecessary since the drain valve is right near the edge of the front pan and even has a stem to attach a rubber hose.
It is possible to remove a rear shock by dropping the upper control arm mounts and leaving the fender liner (and rubber plug) in place. About the same amount of time either way. BTW, the shock is not removed through the hole where the rubber plug was, it just allows space for the top of the shock to move up a few inches so that the bottom of the shock can then clear the half-shaft and be removed.
