Part time 4wd question

Had a mate who was a diesel mechanic and he use to do it to move his heavey boat, I do it in the Jack yo back my boat up by drivewayto savethe clutch, so I cannot see any issuses.

I used to do it on my GQ for backing the trailer up a tight dirveway and it never seemed to cause a problem.

I figure it engages the front diff but if the locking hubs are not in then the drive is just spinning and you won't get windup.

If you don't steer too much and the drive is not too long you should be able to put the hubs in and do it in 4L. The big question is what is too much?

It won't break the second you do it. Provided you give the transmission an opportunity to un-wind when you are finished things should be OK.

Hi toyo13

I think the reason Toyota and probably most 4wd manufactures engage 4wd with low range is that by doing this you have effectively halved the gearbox output speed and doubled the torque. In a scenario where the driver is using the clutch rather abruptly together with a large application of right foot you could conceivably damage rear driveline components. To spread this increase in available torque drive is also diverted to the front. I personally use low range with the front hubs disengaged to manouver our caravan into or out of tight situations but always use the accelerator in a judicious manner and have never done any damage

Hi Toyo 13,

I do this to my rodeo and (as long as you keep your speed down) I cant see how youd do any damage.

Some people on this site put there troopys in low 4th gear to take larger caravans down steep hills

I do this all the time in my GQ Patrol. As soon as I enter the driveway...straight into low range -hubs unlocked. .... just to make clutch life easier and can just idle about the yard slowly and safely.
Also when I need to park / back up my camper trailer...straight into low range ...usually with hubs out..unless muddy or steep. This is a big help as I can swing from lock to lock easily and quickly ...and back just using clutch and brake without touching throttle. I also believe that doing this prolongs clutch life immeasurably.

Cheers Keith

I do it to reverse trailers up my driveway.

Hi Toyo13

In the 100 series cruiser you can engage low range without engaging diff lock, need to modify the wiring on pin 7?
May be similar on the troopy.

Cheers

If you're going to do it, make sure the vehicle is stationary before shifting the lever.

Of course it is possible & a very wise move for moving your van. I have done over
half a million clicks in low range, with hubs free while spraying ,without any issues.
