I have a 2005 4.2TD wagon which I use to tow a 2.5 ton dual axle caravan.
I’ve recently encountered some very steep hills that I’ve been caught at lights, round-a-bouts and when taking off in first I have had real trouble getting a move on.
What are your thoughts in engaging low range to get up these hills and then back to normal driving.

You need manual locking hubs to be able to do that.
I took the auto mechanisms out of my hubs to be able to move my caravan around more easily without binding up the drive line. Recently fitted a Lokka so glad I had the manual hubs already.
No worries at all, it will put far less stress on your vehicle.

No need to lock your hubs.
Low range two wheel drive will do what you're asking.
4wd on bitumen not good at all.
I did some googling on how far you can go before bind up occurs and there's no clear known answer.
If you have freewheeling hubs, no probs at all. Also consider using stock size tyres if you're not already.
I believe Jeff Old Mate Legend was referring to a 2005 GU being a factory set of Auto Hubbies from factory?
If selected LR on hard tar your beaut beast will lock the front axles and need careful consideration of turning/feeling/listening prior to binding explosion [emoji95][emoji23]
Plenty of times on my old 2000 GU Leafy ute I too had to select LR for getting ridiculous tonnage up of the hill lights but they did ute come factory with ‘Manual Hubbies’ [emoji106][emoji106]

FWIW: There is a reason that Trucking Legends (not me) can GCM haul 60,000kg say with ‘relatively’ power to weight ease.
Gears/Torque are where it’s all at, as long as you don’t drive a Toyoda, they explode under pressure [emoji2959][emoji23]

Some say I need manual hubs, others say no problems. I have original hubs.
I’m not talking about long distance driving in low range, I’m just considering using the low range to get moving off the mark, after I have stopped in hills and need to take off with loaded caravan.

If you have the factory auto hubs, don't use 4WD/low range on hard surface roads.Quote:

Upgrade the turbo and fit a performance pump.....and clutch....
No more hill problems...:smiley_thumbs_up:
...otherwise, convert your auto hubs to manual, or fit manual hubs from a ute or DX wagon.
… or convert it to auto trans :)Quote:

Short answer is Yes but all the reasons above re the hubs is true.
If you have a Factory TD42T them you will be running 3.9:1 Diff ratios. Your car will be a far better tow pig running some 4.1:1 will make a difference for sure.
Changing different ratios will also lift your cruising rpm up a couple of 100revs and your TD will thank you.
Your TD42T HATES 2000rpm. Don't cruise at 2000rpm. Do you have a EGT Guage? If you don't you should fit as a matter of urgency.
You will only get transmission wind up if you travel in 4WD on hard surfaces AND turn corners. When you turn corners your front and rear wheels travel different distances and that is where you get lock up. If you take off from lights in a straight line there is no problem - just remember to change to 2WD as soon as you can.
Oi Billy Wigglestick, you don't need 25 posts for the manuals. Stop posting shit.Quote:
