So my buddy just bought a 1995 jeep grand Cherokee 5.2l v8. its full time 4wd. On it it says to use 4wd lo for towing.

My question is since his is full time and mine is part time if i wanted to tow anything would i use the 4wd lo setting? i'd think not but i'm not sure.

I'm just curious because i know part 4wd isn't supposed to be used on dry pavement. I've also been told that 4wd lo is meant for more torque and speeds lower than 25 mph. and that part time 4wd hi can be used at normal speeds but why would you? the only times you need it are when the roads are bad ( either snow or mud).

But I've heard people say they've used their part time 4wd for towing their boats, trailers, pontoons or whatever kids are towing these days. (I'm still a kid too lol)

Whats the deal with part time 4wd and towing? I looked online and couldn't find anything online that seemed useful to me besides the basics which i kinda already know.

 

Don't do it. Like you said, part time 4x4 is for when you need more traction. And your truck is not meant to be run in 4x4 on pavement. Maybe the jeep is suggesting 4lo for towing other vehicles out of holes offroad. 4lo changes your gearing in the transfer case. For example, if you had 3.55 gears, they would now be something like a 6.00 or 8.00. You don't want that. You'd be doing 4500rpm at 45. Not cool. Maybe i'm missing something about the jeep, but it probably has quadratrac or something, and the rules for using that are much different than your regular transfer case.

 

Right, well I'm not planning on towing with my 4wd. I was just curious because it had a factory placed sticker on the drivers mirror hanging above. "4wd lo- for towing" is basically what it said. I found that strange but I'll look more into the '95 grand Cherokee's full time system.

 

i would never use 4wd lock on dry pavement EVER, that includes high and lo

however i do know alot of people who use 4wd lo for towing their boats up the launch ramps, however they switch to 2wd once they get to the parking lot and drive home in 2wd, simply put 4wdlock + dry pavement = big problems no matter what kind of vehicle you are driving

 

Well thats what i assumed for me. but his is full time 4wd he doesnt have a 2wd option. and it says to use 4wd lo for towing. I'm confused between the differences between the too. SOMEWHAT lost i should say.

 

If it were me I'd be towing in AWD or all time 4wd than switching to 4lo but that's just my .02 worth. Just sounds bad towing in 4wd if it ain't off road.

 

in his case he would use 4lo on the same situation as you, and awd will be used like your 2wd, its that simple

 

What it is talking about is if you need more power for towing like through loose road conditions then choose 4low for added traction and towing capabilities. The problem is that you need to have loose surfaces, so this what this usually means is for pulling your buddy out of a hole on the trail, not towing down the road.

 

I see. Well either way i'd tow in 2wd and him in his regular 4wd, I'm not a fan of the full time 4wd. I like having 2wd. its fun sometimes.

Either way i think i now know what i was looking to find out...hopefully lol

 

I think full time 4wd is the exact same as AWD and it lets all four wheels turn at different speeds whereas 4wd like what WE have os all wheels turn at same speed, as long as they arent spinning. At least that's what I understand of it from my old 2001 5.0L explorer AWD.I honeslty would prefer AWD because you get 100% traction all the time and it definitely helps tires wear more evenly. thats MY .02........
