2007 Toyota Hilux, 2.5 Turbo diesel 4 cylinder, 5 forward standard transmission. Car is in great condition mechanically but I have fitted 33’s over the standard 30.5” tires.
Was driving up some really steep hills with 180° switchbacks. These hills are approaching a 75% grade or higher.
I feel as though I’m losing power on the really steep sections unless I just floor it. Which is unsafe because a car can come speeding down in the opposite direction.
Is it ok to put the transfer case into 4-Low, I've heard this causes transmission windup. In 4-Low 2nd gear it’s absolutely no problem I can go as slow as I want but it’s difficult to steer. Or should I leave it in 2wd 1st gear and ride the clutch?
Eventually i’ll get some reduction ring and pinion gears but what should I do until then.?
You shouldn't use 4WD on pavement.
Loss of power, as you found out, is the downside to fitting massive tires. Usually people change their axle gearing at the same time with the tires to counteract this. This is the money pit you land in with 4x4 toys that people don't tell you about.
I think you will just have to go slow and be patient.
1st gear will stall in 2wd
then your truck isn't road-worthy as it is
I usually see people swap out the little diesels in the Hilux for bigger gas engines.
LS3/1UZ swap now we’re talking money pit😅
I use four low so I can care myself unless you're a no big hurry then use the first gear
I don’t mind going slow but 2wd first gear will stall
