Chid 6,376 Posted January 6, 2016 Report Share Posted January 6, 2016 Think I'm missing it here. A G wagon has constant 4 wheel drive by virtue of the the fact that the diffs work together making each revolve at the same rpm. All wheels at all times are driving. Any other vehicle requires manual override from 2 to 4 wheel drive. Am I wrong? Also. A comment made about 4 wheel not being able to corner is a bit of fluff. We know that you can wind front and rear axles at a different rpm but to be honest it would take a lot of miles. yes you are wrong ... a g wagon is 2 wheel drive till you select 4 wheel drive Quote Link to post Share on other sites
rob284 1,678 Posted January 7, 2016 Report Share Posted January 7, 2016 A land rover discovery is constant 4wd with all 3 diffs open. When you do something challenging you lock the centre diff giving 50/50 drive to front and rear. Not many cars are true lockable 4wd it would cost an arm and leg to mod your truck to get all 3 diffs locked. But the discovery 2 doesnt have any lockable diffs as it used traction control to keep traction on the ground, thats how most modern cars work now Quote Link to post Share on other sites
mad4it 693 Posted January 7, 2016 Report Share Posted January 7, 2016 unimogs are constant 4wd but they are more tractors than cars, going back to discos they are prem 4wd in that the drive go to both axles the diff lock in the gearbox locks it so the power does not get send to where it thinks it needs it, Quote Link to post Share on other sites
Deker 3,452 Posted February 9, 2016 Report Share Posted February 9, 2016 No car is constant 4wd.unlesd locking diff I always believed,they won't turn or go round corners if all 4 are pulling equally. I can go round corners on my 4WD locked Diff, but its very hard work and a big turning circle, it also feels like the motor is trying to rip itself apart! Quote Link to post Share on other sites

I can go round corners on my 4WD locked Diff, but its very hard work and a big turning circle, it also feels like the motor is trying to rip itself apart! My Suzuki is the same in 4wd on tarmac it even tries to cock a back wheel if I go full lock its fine down roads ect just doesn't like a tight turning circle ... now I know why Edited February 10, 2016 by kanny Quote Link to post Share on other sites
