Flat towing question

Texas allows you to tow 4500lb without brakes. Curb weight of an LJ is 3700, GVW is 4600. I guess it is a roll of the dice - I would not be towing more than 4500, but hard to tell what the officer would think.

Flat towing a TJ without supplemental brakes is asking for trouble, whether that trouble be an unwanted encounter with law enforcement or an accident on the highway or on wet streets.

Do you feel lucky? I don't mind challenging Lady Luck at the Blackjack table, but not with my life or the lives of those I care for.

BTW, do you know your TJ's actual tow weight? Curb weight is meaningless. Having your vehicle weighed at a public scale is easy and cheap.

I towed my empty car hauler over the Ortega from Lake Elsinore to San Juan. My buddy managed to remove the wires to the trailer brakes using it as a brush hog. The truck was a long bed club cab V-10 Dodge 2500 so not puny by any means. Normal car hauler, roughly 2500 lbs empty. It was not a fun drive. I'm not sure how or why anyone tows a TJ or TJ Unlimited without supplemental brakes.
 
Someone smarter than me needs to explain that some. If the t-case is in neutral, the transmission isn't turning. Why does it need lubrication?

You should really rely on your owner manual but if you need some logical reasoning. Jeep tranny bearings don't get any lube if the input shaft is not spun by the engine. If there is enough friction through the xfer case, leaving the tranny in neutral may let it spin by the output shaft without lube. Leaving it in gear or park prevents that from happening.

No, I won't being doing that since they clearly state that you can't tow a TJ on a front wheel dolly or damage will occur and far too many rigs are running around with front hub kits show that to be erroneous information.

That is clearly logical.

What is not clearly logical is your statement to leave it in third to maintain lubrication which is bizarre since nothing is turning, so it doesn't need lube.

Better would be to state to leave in gear to take the lack of lubrication out of the equation.

Agree. I don't understand the logic. It seems like auto or manual, it shouldn't matter.
It does and for the reason mentioned above, the transmission is not being lubricated when you're flat towing even with the transfer case in Neutral. That's why the factory specifies transfer case in Neutral and transmission in Park or in gear.

Since a couple of you don't believe us, simply refer to your owner's manual where you'll discover it says the same thing we're trying to tell you.

At this point, my flat towing is generally getting it to the shop without needing a second driver. If I was flat towing longer distances or more often - I would be looking harder at a brake system. Shop is about 10 miles on a farm road. Abet I am using a 3/4 ton nothing larger.

I do have a trailer that can handle the jeep and has brakes - but honestly the additional weight of the trailer makes it a harder tow than just flat towing. (it is heavy equipment trailer - so when I put the Jeep on it, it is probably closer to towing 11k lbs. So far my longest tows have been with a car hauler with brakes, then with my heavy equipment trailer. I run the risk of a ticket with the heavy equipment trailer as well - as it is an ag trailer - cops can say the jeep is not an ag vehicle...

And next flat tow question is… do you have your TJ brakes linked somehow to the pull vehicle brakes or just tow it without? Again, I’m totally new to this and need to tow it about 600 miles.

I flat tow my LJ, here is the brake system I use. It is permanently mounted in the Jeep and applies the Jeeps brakes when I apply the tow vehicle brakes. I put my Jeep on a scale a few years ago. With the hardtop, steel skids, bumpers and 35” tires with gear it came in at 4900#. I have since cut some weight but have not reweighed it.

I believe the owners manual says that. I'm trying to understand the physics. If the motor is off and the transfer case is in neutral, what is causing the transmission to get lubricated?

Nothing. The transmission is not being lubricated.

The reason one leaves an automatic transmission in Park or a manual transmission in gear when flat towing is so that nothing in the transmission spins while the transmission is not being lubricated.

I have the same question, putting aside the "don't raise front wheels", which is 100% exactly the same as installing locking hub." This looks to be proof Chyrsler puts out warnings that aren't needed.

If we did just listen to the Owner's Manual, nowhere in the manual does it say anything about lubricating the transmission. Too many posts are stating this in the same breath as what is actually stated, and providing confusion that let's nonsense get spouted.

Seems from reading, for a manual, put it in gear. There's no reason for any gear to be picked, just personal preference on an "IF" the Transfer case suddenly gets slammed into gear, while being pulled, while in motion. Not sure this is really that good no matter what gear, but ok I get the "just in case" I guess.

I cannot see any logical reason that the Trans needs to be lubricated, if it's not moving, which it shouldn't by any logic, be moving. Seems to me, that it's just a valid a guess that someone somewhere, thought "if it's in gear, the dam thing won't rattle around, for WHATEVER reason." If it doesn't rattle around, then it doesn't need lubrication....ipso facto these posts about lubrication.

Either way, the owner's manual doesn't address it, at least mine doesn't for the 2005. Just says put it in gear (and P for Auto). If people are dreaming up the why, which is a valid question, so stuff doesn't rattle around is as good an answer as any from what I can see.






START EXACT QUOTE FROM OWNER'S MANUAL:

Use the following procedure to prepare your vehicle for

recreational towing.

CAUTION!

It is necessary to follow these steps to be certain that

the transfer case is fully in N (Neutral) before

recreational towing to prevent damage to internal

parts.

1. Depress brake pedal.

2. Shift automatic transmission into N (Neutral) or de-

press clutch pedal on manual transmission.

3. Shift transfer case lever into N (Neutral).

4. Start engine.

232 STARTING AND OPERATING

5. Shift automatic transmission into D (Drive) or manual

transmission into gear.

6. Release brake pedal and ensure that there is no vehicle

movement.

7. Shut the engine off and place the ignition key into the

unlocked OFF position.

8. Shift automatic transmission into P (Park).

9. Apply parking brake.

10. Attach vehicle to the tow vehicle with tow bar.

11. Release parking brake.

CAUTION!

Damage to the transmission may occur if the trans-

mission is shifted into P (Park) with the transfer case

in N (Neutral) and the engine running. With the

transfer case in N (Neutral) ensure that the engine is

off prior to shifting the transmission into P (Park)

(refer to steps

7 – 8 above).
 
I tow my tj behind my motorhome with a Ready Brute Elite 2 system. I like it and it uses a simple surge brake which works well. The are several good tow bars out there but it can get very expensive. The Ready Brute system is not cheap but is one of the cheaper ones.

I want to flat tow with my 2019 Ram 3500. Are there any brake systems that can use my factory proportional brake controller?
 
Texas allows you to tow 4500lb without brakes. Curb weight of an LJ is 3700, GVW is 4600. I guess it is a roll of the dice - I would not be towing more than 4500, but hard to tell what the officer would think.

Better safe than sorry.
 
Seems I could unlock steering wheel by turning key to first or second click w battery disconnected. I have a battery quick disconnect installed. I want the steering wheel to be able to turn, right?

All you have to do is turn the key back one click from the run position. ‘No need to disconnect the battery.
Note: You will not be able to remove the key from the ignition switch. This is normal.

Hoping you can answer. When should I run the jeep while towing i.e. it will be in tow mode for 3 days - do I keep it set in tow mode and run for 30-45 mins when I stop ?

I never heard the engine needs to be run at all on multi-day tow trip. What makes you think it should be run?

My practice is to start the jeep's engine when I am at fuel stops for the tow rig and run the transmission through the gears with the transfer case in neutral to sling oil. It takes a couple of minutes, not 30-45. Then I put the transmission back in park (or in gear if a manual transmission), confirm the transfer case is still in neutral and the steering is still unlocked, and continue on my way.

This practice has worked without issue since I first flat towed a jeep in 1966. Jeeps with gear driven transfer cases such as the D300 were sensitive to lubrication issues when flat towing and old habits die hard, but I still follow this procedure even though I must admit that I don't always run the jeep engine and shift through the gears at every fuel stop, but at least every second or third.

Can I ask why on a TJ? The manufacturer specifically doesn't say to do that.

I get in 1966, and 1976 with my CJ5, I do that, but with the TJ, it's absolutely unnecessary. Just curious, out of habit?
