Towing over weight.

I am aware of the dangers of towing more than your jeep is rated for, so we can skip that part. I'm not the one doing it and I advised against it just to make that clear. What possible damage can be caused to the drive train from towing over the GVWR? Someone I know is towing a 6X12 cross country and the weigh slip was at about 10,000 pounds. This is a 4 dr wrangler 3.8L. Looks to me like they are at twice the rated gross weight. I am concerned about this situation, But they already left.

Going downhill is probably the easiest part. The trailer has its own brakes so should be ok. It's pulling up hill and the strain on the drive train. Especially the weaker 3.8 with a 4 speed auto. Also the pressure on the rear suspension. Headlights are probably aimed at the moon lol!

What damage he does to the engine, tranny, etc. is on him. However, when he looses control and ends up rolled over in a ditch or even worse kills someone...that will also be on him.

I'm also willing to bet that he has exceeded the max tongue weight and it's a time bomb on the weakest link probably the tires.

Hopefully, he'll get picked up by the cops before it's too late.

It doesn't matter if the trailer has it's own brakes if the Jeep doesn't have a brake controller box.

That's closer to 3x the tow rating.

Other than being extremely not safe in crosswinds: Trans will be the first thing to overheat and go. Hopefully he put it in a trans cooler. Hope he followed the manual and changed his diff fluid. Engine will struggle as well, probably no instant damage but things wear out quicker under that kind of load.

Hopefully... he did NOT put in a tranny cooler..... then he will be sitting along side the road someplace!!!!!!!!!

Guess we will see what happens, to late for me to stop them. They already did a 12 hr leg of the trip. Its a stick shift not an auto. Female driver that didn't check the weight while they were loading. So far just a blown fuse, but that could be from a short on the trailer as it wasn't a problem before.
Bad idea in my opinion.

I reread the post. The combined weight of vehicle and trailer is 10,000. Not the trailer alone. Still scary.

This is grossly irresponsible and I hope they get pulled over and impounded. Tons of repurcussions, but no deaths.

Omfg what an idiot. Saying that, hope it turns out ok as far as safety - love to see tranny blown so they don't do it again. I would hate to try and explain someone's death on that mistake.

Not every trailer requires you to have one for the brakes to work. Many just work off of the a tongue rod.

Trailer brake controllers are not hard to add... I put one in my 2012 for my 4x7 camping/utility trailer, just for added safety and offroad use

With a weight distributing hitch I say no problem. Pulling that trailer is no worse on the engine and tranny than a hard day mudding or doing soft sand. You guys do realize that engine and transmission go into vehicles that are rated to tow that much weight.

Cross winds and trucks passing would be a concern but I doubt any mechanical damage will be done if he knows his stuff.

If I was going to set up a jeep for towing. I would be looking at a load equalizer hitch, brake controller, stiffer suspension, possibly air bags, and a v8 swap. But I also would not intentionally over load a trailer. This particular situation the person loaded the trailer with a uhaul hitch installed and left. They hit a weigh station on the way out that's how they found out it was over weight. I would have helped figure out a solution if I was home, but I'm not. This was not an intentional act and they were to far into the trip to turn around. I didn't start this thread to hear comments on how stupid it was. I am very aware of that. I was seeking information on what they should expect from the jeep since they have already left. To be honest the reports I'm getting are that the jeep is handling fine just a bit low in the rear end. If they had thought the handling was off or if it had looked really bad when hooked up I don't believe they would have left. Currently they are trying to drop stuff to lighten the load.

It's a manual tranny so the clutch will take a beating. The brakes as well.
The engine may get hot but modern engines have good safeguards. I would advise they keep it at 55 mph.

As far as taking weight off, take it off the trailer. You don't want the weight of the trailer to exceed the Jeep's.

It's clear that many of you don't have a lot of real towing experience. It's not about the Jeep having enough power, or the right transmission. Many of them are subjected to far worse forces while offroading and are just fine. The biggest issue is that of weight management. With this being a four door, he is at least that much ahead of the game when it comes to control. A trailer that big will have it's own brakes and also probably surge brakes. If so, no controller needed. My money would be on him making it to his destination without an issue. Tongue weight would be my biggest concern in his shoes but road conditions will dictate if that will come into play or not.

You guys are making a far bigger deal of this than needed. Far more has been towed with far less.

1300 miles so far. Temp has stayed the same. No clearance or stability issues going through the mountains. No adverse steering effects. Not saying that I like it or think other people should try it. Jeep is holding up well and the driver has more towing experience then some people I know.

Correct me if I am wrong, but OP stated the trailer weighed 10000 lbs? I get Jeep probably rates the vehicle low to give some wiggle room, but almost double?

I towed my 32 foot trailer with my Ram 1500 across country - the trailer weighed in at dry 6900Lbs (with gear probably closer to 8000lbs). The Ram did the job but it wasnt perfect & that was considering i had a good WD hitch, trailer brake controller & some common sense. My tranny temps went high and then dropped when the cooler kicked in. Does the Jeep even have a tranny cooler? I dont know but I suspect it wouldnt.

Does the Jeep have the correct tires is a good question - I had the right tires on my Ram but even still it sucked watching the tire pressure increase on the back tires when the trailer was on.

I dont have a lot of towing experience but it seems to me that these things can only do so much..it wasnt designed to do what its doing and depending on insurance/warranty i bet if something happened then all bets are off.

just my .02

Don't get me wrong. I am NOT saying this is a good idea. I'm also not saying that anyone should attempt it. All I'm pointing out is that the general tone in here has been like the guy is going to erupt in a ball of flames and kill a bus full of nuns or something and I'm just saying that's far from likely. I do agree that he's screwed if something does happen though. Insurance won't touch it.

No the weigh slip was for the jeep and trailer. weight total was right around 10,000 pounds. So 4297 pound vehicle hauling a 5703 pound trailer. Of course the vehicle was loaded also so it could be a 50/50 split between the jeep and trailer. Either way its 2x the tow rating. I don't like it but its the facts. I do care about the welfare of the people involved in this trip even though they didn't plan ahead. 1 trailer was not their original plan but plan A, B, and C fell through in this situation. They were left in a need to leave now situation. They did not weigh the load until they had already started on the trip. The person driving the jeep has a lot of past cross state lines towing experience but it was with a truck. Longest haul with a jeep before this venture was 5 hr one way. Current situation is a jeep hauling a 6x12 with dual axles and brakes. 1300 miles down with out incident or major problems. I started the thread not because being told that these people are idiots would make any difference since they left already but to try and have some sort of useful information available if they started noticing something wrong. They are well aware now that the vehicle is over weight and that what they are doing could have very bad impact on themselves or others. I have gotten very little to no useful information off this thread but can not delete it so the show must go on. Thank you to the people who did post something worthwhile.

Remember the old Paul Newman movie "Cool Hand Luke"? ......"What we have here, is a failure to communicate". From your original post, I, as well as probably some others, took it that the TRAILER weight was 10000 lb.
Now you are clearly stating that the Combination weight was 10000 lb. There is quite a difference.
The receiver hitch on my Super Duty is only rated for 6000 lb. as a weight carrying hitch, and 12500 lb. as a weight distributing hitch.
So, with this, to try to pull a 10000 lb. trailer cross country with a JEEP would be highly irresponsible. As an old OTR trucker with around 2 million miles behind me, I have seen way too many wrecked outfits pulling trailers that they WERE rated for. So please don't flame us for understanding things in a way that was not clearly posted.
Have a good day. And I hope that your friend gets to his destination without incidence

Fair enough, my bad. I meant to present the information a bit more clearly then I originally did. I did later correct myself and state that it was the combined weight. Not sure what flaming is. I am guessing that it involves hateful words or a lighter. I have a lot on the plate right now, and honestly didn't mean to offend. Enjoy your day, its night at my location. I will check back with you all later.

I understood would you meant. You said the weight slip was 10k. Hell, I don't think a 3.8 could even MOVE 15,000 pounds (Jeep plus trailer)up to a highway speed let alone pull it across the country!
