4 hi prob

When im out wheeling i come upon some steep hills. I out it in 4 high. It starts good going up the hill then dies down as i get further. I have to push the clutch half way in to keep it going. it Only happens in 4 high tho. 1st gear is what i had it in. 4lo works great on steep hills. Any advise? .


if you are telling you self you cant before you have even tried, you are a failure.

Go up the hills in 4 lo. You are going to burn up your clutch pushing it in half way to keep the RPM's up.

You quite obviously don't have the power to run the hill without the gear reduction of 4 low. The high range 1:1 ratio requires all the power of the engine and doesn't rely on the lower gearing of low range.

Maybe 4hi just isnt enough to make it? I know my jeep wont do most hill climbs or obstacles in 4hi, just doesnt have it in her. 4low is where its at with the 4banger

Sounds like your not geared low enough. I'm running 3.07s and I have the same problem with mine.

You have the 2.5 same as I do. Its a great engine it will take a beating but it doesnt have the power of a V8. You need to put it in 4lo its rare that I even use 4hi I just put it right into 4lo. In 4lo youll climb a tree with no probs. Just put it in 4lo and go.

I had the same issues, way better since the gear change. I always hated going into 4LO. did not want to always lock up the front end. Went from 4.10's to 4.88's and put in an ARB. Well worth the money I spent. It took me a year to collect the parts. Now I have traction with the back steering with the front and the gearing to climb a lot of hills in 4HI. I should mention I do have the 4 banger.

The front is locked in in 4hi the same as 4lo.

This is true. The axle locks either way.
Your engine just don't have the kahunas for the climbs you are trying to do. They are all right above. You need to do them in four low, no two ways about it unless you regear.

I can lock the ARB in the back have some great traction of two wheels pushing the car and leave it in 2HI. Works great on steeper hills with loose dirt on top of hard pack where speed is needed to climb and I may have to turn sharp at the top.

Does anyone run there 4 cyl. (Standard shift)Jeeps in 4 low, sometimes in 2nd or 3rd gear? Will this hurt the gears? I've owned an old Toyota pickup w/ 4 cyl. And ran it a lot in 4low in 2,3,4 gear. Never seemed to have any problems but it was only a bush truck.

I run mine in low and put it in whatever gear I need. I have never had any problems.

^^^^This 4lo second gear takes me everywhere in my 4banger. I only need to use first if it is a really really steep hill and I have several passengers with me or my trailer loaded up for a week long camping trip.
