Treasure Hunter Posted February 25 Report Share Posted February 25 Any input in leaving the 4 wheel drive in high all the time for local and freeway driving? Quote Link to comment Share on other sites More sharing options...
TrevC Posted February 26 Report Share Posted February 26 Hi Bill....welcome to the Club I have always been of the belief that it is not advisable to drive in 4WD High or Low on hard road surfaces, as this can lead to transmission wind-up which can damage internal components. You will notice a clunking on cornering at slow speeds which is the transmission (differentials) fighting to corner at different speeds. If you have freewheeling hubs disconnecting the drive to the front wheels then this helps but not good to use on the freeway, best for off-road driving really. Saying that, it is necessary to drive on soft ground in 4WD every so often to keep everything moving otherwise this can lead to components seizing in position (selector levers, etc) I drive my Mitsubishi L200 in 2WD and occasionally shift to 4WD High and into 4WD Low on dirt tracks Quote Link to comment Share on other sites More sharing options...
Treasure Hunter Posted February 26 Author Report Share Posted February 26 Thank you for your reply. I've read in other posts that it is o.k. to drive in 4WD High all the time. My mechanic says what you are saying, not a good idea. Bill 1 Quote Link to comment Share on other sites More sharing options...
Lexus Owners Club Posted March 1 Report Share Posted March 1 Should also increase your economy if you're not dragging the additional drivetrain when driving (2WD high is better for mpg) Quote Link to comment Share on other sites More sharing options...
Treasure Hunter Posted March 1 Author Report Share Posted March 1 Yep, I'm getting the same from my mechanic here in DE. Thank you, Bill. 1 Quote Link to comment Share on other sites More sharing options...
