Hi everybody
Could you please give me advice on driving in 4x4 high ratio. My other half has some urgent hospital appointments and operation coming up very soon. The hospital is a 100 mile round trip and knowing the weather here is Scotland the trips look like they will be undertaken in snow and ice. We have only used the fourtrak for getting out in winter to the local shops and back. Its been well maintained and has never let us down. Its got 140,000 on the clock. My question is - is it OK to drive that far in 4x4 high ratio and what is the maximum speed we should keep too. Since we have had it the jeep has never been driven more than 30 mile round trip at any one time. Would be grateful for any advice.
Thanks for any advice from a driving novice.

used sensibly you can doo the trip in 2h and 4h, if you read the fourtrak handbooks and some posts on this forum, it says - do not drive on tarmac in 4x4, the transfer box is a 50/50 power split, sending the same amount of oomph to the front aswell as the rear, this means if your wheels are gripping all round it is actually possible to rip a tyre of a rim when turning because of tge push pull force, now I dont know if you have auto/manual or fixed front hubs, or electric switch or manual 4x4, but if your on a stretch of road thats icy/snowy, yer use it, tyres will be able to slip, if the ground is dry, knock it into 2h, if you dont you'll start grinding the teeth out on gears, by fitting really super grippy mud tyres the need for 4x4 use is lowered anyway, hope this kinda gives a bit of help/info.
Full of ideas but no time to do them!!

2h and 4h
Sorry for being stupid but I was under the impression that once you come out of 4h with automatic hubs (yes I know - wish I had manuals) that you had to stop and reverse to unwind the hubs. Is not doing this and just switching between 2h and 4h OK then?
Never use the vehicle in 4H
Never use the vehicle in 4H on a solid surface such as a tarmac road as the front and rear propshafts are locked together, in snow and ice this is fine, in varying conditions you switch from 2H to 4H and back to 2H as you need to.
You have no centre differential and you need one to drive in 4H on a solid surface as the axles turn at differing speeds as you turn corners and a centre diff allows this to happen, hence the reason my Mitsubishi Shogun is in 4H as this has one. You can cause transmission wind up and it can smash a U/J, destroy an axle, blow a transfer case, or even trash the main gearbox if you are really unlucky.
If you have manual hubs you need to stop at the onset of ice and snow and manually engage them, if they are auto hubs you don't need to do anything; then just select 2H or 4H as you need to. I would stick to a maximum of 50MPH in 4H.
Yes, its fine. You only need
Yes, its fine. You only need to reverse if they don't disconnect and this usually happens through lack of maintenence or when the hubs are very cold such as engagement in snow and ice and you have driven less than a couple of miles.
