lexus300rb

Hi wwest, A friend of mine, all around mechanic, says disconnecting rear driveline would screw up the VC(whatever that does?). Better leave well enough alone, he says. I still think there is some thing that's always worth a try, disconnecting rear wheels seems less drag on engine. Have to look up what this VC does or it's purpose.

To clarify... To tow a FWD vehicle 4-down all you have to do is use the kit to disconnect one halfshaft. With a RWD the kit provides a means to disconnect the rear driveline. With an AWD such as yours or mine the rear driveline and one halfshaft would need to be disconnected. Since yours is a 2000 and therefore doesn't have TC, traction Control, nor VSC, Vehicle Stability Control, nor electronically implemented AWD (braking) there would be no electronics problem with disconnecting the rear driveline. Since the engine torque is so heavily biased to the front I would not advise disconnecting either front halfshaft in order to disable the front driveline. But keep in mind that MY2000 FWD RX300's did have TC, and north of the snowline often needed it.

hi wwest...boy, that's quite a reply to my question. I didn't know that removing a drive shaft from between the front and rear would be causing a biasing problem. Really, would a drive shaft removal cause any electronic problem with the computer (or whatever) knowing that the rear wheels aren't driven by the trans axle?

I have a 2000 RX300 AWD that I would like to change to 2WD for the summer months. Any easy way of doing this? Lexus should have made this an option. Anyway, thought this change would increase gas mileage. Any help?
