Flat tow CJ-7 across 11 states

First post,

Very late for this request but I'm heading to Rhode Island this weekend to pickup a '77 CJ-7 and towing it back to Florida. I've been reading the opinions on flat towing & have distilled it down to:

<ul type="square">
Remove the rear driveshaft at the rear diff,
Strap it to the Jeep's underside,
Put tranny &amp; transfer case in neutral,
Bungie the steering wheel to help it return,
Haul it behind a BIG truck.[/list]I'll be dragging it back with a '93 F350 7.3L diesel 4x4 crewcab. The tow bar should be level from the truck rear bumper to the Jeep front bumper. I've got a 5000# bumper hitch &amp; Reese 5000# towbar.

I know, I probably could have done this another way, but this is the only option now. Any feedback on this from you experts at this would be greatly appreciated.

Thanks

Re: Flat tow CJ-7 across 11 states

You mean rear driveshaft, right? If so, then you are correct, just unbolt that sucker from the axle and strap it up out of the way. It probably doesn't matter what gear you're in if you do this, since nothing will be causing the drivetrain to spin, but probably still not a bad idea.

Re: Flat tow CJ-7 across 11 states

Thanks for the quick reply, a bit of nerves on my first plunge. Yes, I mean the driveshaft. I'm planning to use enough bailing wire that it won't go anywhere. Don't want it falling out on the way home.

Re: Flat tow CJ-7 across 11 states

sounds good to me. however, why not remove rear driveshaft and not worry about falling out?
good luck

Unlock the front hubs. If you remove one end of the rear driveshaft, wrap the u-joint with tape so you don't loose the two cups. Also, DO NOT put the trans and transfer case in neutral. It shouldn't matter but make sure nothing spins by leaving the trans in gear and the transfer case in 2 high.

You don't say what drivetrain the jeep has in it. If is is quadratrac, remove BOTH driveshafts if you remove them. The quadratrac can be flat towed fine with the trans in park and the transfer case in neutral.

Re: Flat tow CJ-7 across 11 states

I've not yet seen this Jeep, just pics &amp; descriptions. Its a '77 CJ with a T-18 &amp; Dana/Spicer 20 transfer case. Unlocking the front hubs is on my list-just forgot it in the post.

Its my understanding that the driveshaft is just spline/slip fit into the rear of the transfer case. If the axle is totally removed, nothing will retain the gear oil in the T/C. I'm currently out of town &amp; away from the Jeep so I cannot verify this. Let me know if this is correct thinking.

Thanks for the reasoning on putting it in gear. As long as the engine is not running, it will lock the tranny &amp; T/C from spinning.

The Dana 20 t-case should have yokes on both outputs for U-joints, not a "spline/slip fit" set up. So IF its still original you should be able to unbolt the drive shaft at the rear pumpkin and the T-case. Cool find on the T-18, it should be the wide ratio with the 6.32 granny 1st.

If you are briging your own tools , make sure the drveline isn't put together with TORX bolts.One of mine was straps and torx...what a pain.

Re: Flat tow CJ-7 across 11 states

Ray,

Thanks for the warning. I left my large Torx set at home, I do have up to T-30 with me. I'm picking up a friend for the trip in NC &amp; I've added them to my request list. Maybe he'll have a set. Should have found this forum earlier.

Thanks again, good tips y'all.

Russ

Re: Flat tow CJ-7 across 11 states

With the dana 20, there is another way you can flat tow it. Make sure it has oil in it first though.

Lock front hubs
Put trans in gear
Put transfer case in neutral

The dana 20 spins two gears when in neutral and the hubs locked and doesn't have the oiling problems when flat towed that the dana 300 has.
