I have a 1999 4x4 Expedition with a 5.4 Liter engine and a 3:31 open axle, and the owners manual claims a 6400 pound trailer weight rating. Has anyone tried towing heavy trailers with this type of set-up? I have a 26 foot camper trailer that weighs 6000 pounds empty, and I think I may be pushing the truck a bit too much, especially when everything is loaded up. Any help would be appreciated, Ben Willard.

 

I towed a 25' boat with my 97 Expy but it had a 3.73 axle. I just replaced my 97 with a 2001 and I ordered the 2001 just to get the 3.73 rear end (part of the high altitude pkg. I figure my total tow payload is around 6000 lbs. Personally I think you will be pushing it towing with a 3.31 axle. You should not expect it to run in overdrive. I have a friend who towed a 23' boat with his 97 with a 3.42 and that is what he experienced towing under 5000 lbs. I have never investigated what's involved in changing our the rear axle ration but you might consider that.

Good luck,

 

He's right. It might be pushing it. Rear gear would be a good start but I'd look into what rating that would put you at. You'd have to find some reference somewhere though.

It's funny, used to be a 4x4 was rated higher that 2wd always. Now it's the other way around. My 2000 2wd EB Expy is rated at 8000. Through in the mods I'f done and I bet 8000 wouldn't even feel like much. I want to hook up to something sooo bad, just to see...
