I tried to back up a very steep hill in my yard today I started to spin tires so I shifted into 4x4 high and gave the car gas in started to go back I needed more so i accelerated more and herd a loud grinding and the wheels would not spin so I shifted into 2wd and no noise and the wheels spun no noise and in 4 low I was able to back out but I can only give my jeep so much gas only in reverse and on this steep incline in 4 high or it starts to grind it is a 1998 Cherokee 231 tease thanks for the help

 

I found myself gasping for air by the end of that! Did you make sure the 4wd was engaged fully before flooring it up the hill? I assume since you said it was your yard, that the tires were able to slip?

 

Yes I tried twice it was in 4 h and would spin in 2wd but not 4h

 

if there was a load on the T-case odds are it didn't engage. try starting out in 4HI on the flat, see if that works.

 

Ok I will

 

Good suggestion.

 

Thanks so much spot on advise I did an identical test except shifting on flat ground and I was able to spin and get up the hill again thanks so much

 

It's just on that angle it will not engage if I shift on flat ground it will weird

 

Adjust your t-case linkage. You should be able to shift into 4-hi when ever up to 30mph.

 

i know that sometimes i need to shift to neutral to get it to engage because the trans is in a bind and puts stress on the t case so it wont let it engage

 

I had that happen to me when I was "testing" out my locker. I tried to climb a pretty steep hill in 2Hi, I got almost to the top, and started spinning the rears. I let off the go pedel and poped it into 4Hi but it wouldn't engage. I had to back down to get it to unload, from there it went in with no issue.

 

This is how steep it is I tried it more it works great now as long as I shift ahead of time

 

can't really tell by the picture... but then again vids & pics never really show how steep something really is!

 

Mabe this is better

 

that will work, it's good to get an idea of when you'll need 4wd.
