GOOD DAY GENTLEMEN ,
For those of you that need to know , auto free wheel hubs should not be engauged above about 10km/h . They work on a system similar to a ONE WAY BEARING .
When the side shaft turns and the wheel is stationary , the auto locking system activates to drive the wheel . The same applies in reverse . If they are locked pulling forward , when you stop and go in reverse , they will unlock and then lock in reverse the moment there is a bit of rear wheelspin . Engaugeing 4x4 at speed with auto free wheel hubs is really not a good idea ! You have a transfer box running at speed , suddenly trying to engauge a stationary drive shaft ! The 4x4 selector ring has dog teeth which do not like to engauge at vastly different speeds ! NO , YOU DON"T WANT TO BREAK DOG TEETH IN A GEARBOX !
If the hubs are manually locked , 4x4 can be selected up to 100km/h . Over 100km/h is risky , due to possible different tyre pressures causing a slight difference in rolling diamatre , which will cause instability very very quickly ! Patrols can take up to 600KW through the standard drive train without modifications , but you still need to treat them the right way !
Enjoy guys , we'll see you out there !
Can we get rid of STUPID DRIVERS before they kill us ?
