That's not strictly true, and varies between implementations/transfer case designs. In Jeep Wranglers, for example, which have both high and low gearing options in 4WD, the owner's manual will indicate that you can drive at any speed (on loose surfaces such as sand or dirt) in 4HI and 0–25 MPH in 4LO.
- wil421 10y agoYou right that's why I said 10 or so. Try taking a turn at 25 in 4LO. I'm not sure of the use case for 25 in LO. My Grand Cherokee can operate the same way but I doubt I would go into LO at those speeds. It also will switch to 4HI when it detects wheel slip. A friend of mine had a old truck that would randomly switch to 4LO on the highway. It's pretty scary driving 60 and having 4LO switch on.
- brianwawok 10y agoIn dirt taking the turn at 25 is fine. The inside wheel will just spin a little.
- refurb 10y agoOutside wheel wants to travel more than the drivetrain so it would slip, not spin correct? The inside wheel would spin if the outside doesn't slip.
- brianwawok 10y agoOops you are correct
- rpcope1 10y agoMore often than not, even more so than slip, the outer wheel will "hop". This is especially true, if you've done something potentially unintelligent like welding the spider gears together.
- refurb 10y agoNot sure why you're getting downvoted. On high traction surfaces like dry pavement, the outer wheel does tend to hop during turns.
