Tow hook help - stock bumpers
 
Gang, doing my first trail ride this weekend and need tow hooks.

My thinking was to mount tow hooks to front bumper and then use the receiver for:
Smittybilt 7610 - Smittybilt 2" Receiver Tow Hook - Quadratec

Question (searched but the threads that came up all had broken picture links) which front tow hooks are recommended that bolt right in without modification? Seems that nobody has installation instructions that I could find.

Thank you very much in advance!

Your tow hooks should be tied to the frame directly. If your rear bumper has your receiver hitch make sure it is tied to the frame not just to the rear cross member. If you have an actual rear receiver hitch mounted to the frame you should be fine with the tow hook in the receiver hitch.

WredTJ 07-14-2013 10:16 PM

Would I be better of with a different rear tow hook option?

Otto Man 07-14-2013 11:46 PM

How is your hitch tied to the frame? In this picture, you can see the factory tow hook tied to the bottom of the frame. There are nuts inserted through the frame hole right behind the tow hook to secure the bolts. Check out this forum thread for more ideas and good pictures.

Hi Otto, my TJ is getting a quick inspection by a local jeep guru but thought it was mounted to the frame. Will verify later.

Can I pickup these tow hooks at local Jeep dealerships or auto parts stores?

Otto Man 07-15-2013 09:24 AM

You could probably get them at wither place or online. It depends on how soon you need them. Where are you headed to 'wheel?

Mulvihill64 07-15-2013 09:39 AM

Harbor freight has 10,000 lb tow hooks for like $7 that bolt right onto the front bumper. Ill take a pic of my rear hop setup later if I remember.

WredTJ 07-15-2013 10:29 AM

Otto, I'm heading to Badlands with Fox River Jeep dudes and dudettes in Attica, IN this Saturday! Gonna be my first wheelin' experience!!

Mulvihill64, that'd be great, thanks! There's a HF 20 minutes away!

Otto Man 07-15-2013 06:59 PM

I am heading North to the Jeep Jamboree in Mole Lake WI. Badlands is on my list of things to do too. I live in the Milwaukee area. Have fun. You will learn a lot by being out there and from others.

Thanks! Let me know when you go!

I'm very excited about the trip!

Also, I heard there is done wheelin around Kettle Moraine. Know anything about that? I used to bike the John Muir trails and that is a great area.

another rear tow hook option.

WredTJ 07-16-2013 10:16 AM

That's a cool option if they receiver hitch won't work right!

Ironhead Jed 07-16-2013 10:22 AM

i have read a few bad things about using a receiver hitch for a recovery point.

btw, nice to see some more local guys, you'll love the badlands

Indeed it is! Feeling luck over here! Just realized, you are close by too! Howdy, neighbor!

I did search around on the receiver hitch and it seems like most folks like them. Didn't find any bad press but there may be plenty posts Google didn't find. Hmmmm

I've used my D-ring receiver multiple times to haul people out or get hauled out, much better set-up than the hook is.

Thanks, StumpHumper. Is yours receiver hitch attached to your frame or cross-member?

I've tried googling that since I'm waaaaay out of practice with mechanical stuff and cannot tell why only attached to crossmember would be a problem. TJ cross members are metal tubes attached to frame so I would have assumed it'd be fine for recovery since it's okay for towing.

So maybe someone can shed light so I can get smarter?

Holton345 07-16-2013 11:49 AM

If you tow a vehicle you are towing only the weight of the vehicle. If you are stuck in mud or wedged in a crevice then the weight you are towing become many times higher. Tow traps are "beefy" when they can tow more than twice the weight of the vehicle. But a recovery strap frequently tops 25,000-30,000 pounds in what it can pull.

That should tell you that to recover a vehicle you will possibly put 30,000 pounds of pulling force on the strap, cable, hook, D ring, clevis or receiver.

That also goes for the bumper.

The plate that is welded to the ends of the frame rails is not stout and can tear free along with the bumper, turing the bumper into a very large and very dangerous missile that can kill or maim someone.

That is because you are putting *all* of that force on the welds between the frame rails and the plate (crossmember) and not on the frame itself.

Frame tie-ins simply spread the load away from those welds and on to the frame rails, making for a much stronger pulling point.

An example of frame tie-ins would be these here. Many use the same system of bolting the crossmember holes to the frame rail holes.

If you tug hard on the bumper with these, the load goes from the bumper to the crossmember to the frame on both sides of the vehicle. It is very strong and can take these sometimes very stout pulls needed to yank a jeep out of mud or a hole. Remember that you are not simply pulling it along, you are FREEING it from something that is holding it in place.

Thank you very much!!! Is this a proper example of the tie-in:

Yes. The bumper will be bolted indirectly to the frame rail. That puts all the pulling force running down the rail and not onto the welds at the ends of the rails, which can break.

Holton345 07-16-2013 12:09 PM

This guy has good gear and knows how to do this.

Holton345 07-16-2013 12:10 PM

This guy does not know what he is doing and hooked up to a bumper with no tie-ins (maybe) or to the incorrect location (probably).

Holton345 07-16-2013 12:11 PM

You can see that there is a LOT more force involved than with merely rolling the vehicle across a flat surface. The frame tie-ins and a properly designed bumper are a must if you plan on recovery with no damage to your rig or any heavy parts flying through the air! :)

WredTJ 07-16-2013 12:13 PM

Ahhh, I see! Thank you very much!!

Otto Man 07-16-2013 12:37 PM

Eddie sells them on ebay through his Ground Pounder Fab Store and is an active jeep forum user/moderator. You can buy them directly from him with PayPal to save hime some ebay fees GroundPounderFab@verizon.net. These are the same ones I used. The tabs on the bolts make for a quick and easy installation since you do not have to fish a wrench with a nut taped to it up in the frame (though that is not that hard either). Prime and paint them yourself.

WredTJ 07-16-2013 12:45 PM

Those look great and easy! What is it, an hours worth of work?

I sent a note to a local guy who was doing some on my TJ to see if he could do it.

If not, will order these ASAP! Thank you again!!

It's attached to the crossmember, I've owned many different 4wd vehicles and never once seen a factory crossmember get damaged from a simple yank... I'm sure there are circumstances where it wouldn't be advised but in 99% of situations it's not going to hurt anything.

WredTJ 07-16-2013 03:54 PM

Thanks for your experience, SH! A friend of a friend is helping me get this ready for the trip and said a tie-in bracket will be a piece of cake to get done tomorrow or Thursday.

Holton 345, the guy who was backing up to snatch the Jeep SUV does not know what he is doing. The correct way to snatch another vehicle is to hook up to the REAR of your vehicle.

If you hook up to the FRONT of a vehicle, when the strap goes tight, there is a sudden weight transfer to the front axle, just as the driver is applying throttle to unstuck the other vehicle. All too often, the sudden torque loading of the front axle subjects the steering U-joints of the front axle shafts to damaging stress, and breaks the u-joint or stretches the ears of the shaft(s).

That driver had plenty of room to turn around and attach the strap to the rear as he should have. When the strap tightens, less weight is transferred to the rear axle (because the heavy engine is on the front) and the rear axle is usually stronger anyway.

If you have to snatch from the front because you cannot turn your vehicle around, then the correct technique is to go to 2WD to spare the front axle.

WredTJ 07-16-2013 05:31 PM

Good to know!

This is very good to know.
He (the wrangler) probably didn't have a recovery point in the back to pull with. Just a guess
