Tire carrier pivot question

Hi I have been building tire carrier and bumpers for a while now. On my tire carrier I always use a spindle assembly with 2 tapered bearings rated for 1750 lbs. I have been noticing others use 2 hiem style rod ends. And I must admit I am thinking about using them in a new prototype bumper/carrier. I have never used these before. So here are my question. What do you think of them?

they are perfectly fine, potentially better in the fatigue loading scenario than a spindle due to where everything requires welding.

However I think they make more sense for a tub mount style that ties into the roll bar rather than stacked on top of each other as a direct spindle replacement

all that said, you still need to make sure you've got them properly sized.

That's what I run and I have some pointers for you. I have ran this setup for over a year now.
The heims should be as far apart vertically as possible I have about 3.25" between mine and wish i had 5" at least. I also wouldn't use any heim smaller than 5/8. I used 1/2 the first time and they were not up to the task of holding my 31 so 5/8 minimum. its a great system and plenty of adjustment to counteract the added weight of larger tires fuel cans or jacks. My latch is a threaded bolt type so any change in weight makes the holes not line up, so the adjustibility was a must for me. hope that helped a little.

In my mind's eye regardless if you run a spindle, Heim joints, Bronze bushings or whatever a rest for the swing at the opposite end is needed to get the weight off the pivot. There is a lot of leverage there.

I agree. The weight factor plus leverage like you said adds up.

how do the tire carriers that swing with the tailgate seem to be holding up, being that they are using the tailgate to "hold up" the tire? Not sure if I explained that right?? I think the spindle with the bearings would be stronger no??

On mine (pics at bottom) the swing holds both the tire and the tailgate. I could in theory toss the tailgate and just run the swing. But that is goofy! But I have built a swing that is the typical bumper mounted spindle that the tailgate is linked to and the whole works opens as a unit.





That was for my brother in law's Rubi. To my knowledge he has had zero issues.

I've had mine over 4 years now and not one hiccup.

Bigbob, neat set up, both of them. Id like to make a bumper pivoted carrier that is tied to the gate. On the bottom pics, what did you do for the mounts the the tailgate hinges, to beef them up? Everyone says the stock tailgate setup cant handle the weight of a 35" tire, slick set up you got there.

If you look at the above picture close you will see the tailgate has zero of the weight on it. It makes no difference what size tire, the tailgate is not affected. The tailgate, just like the tire, mounts on the swing.

Here is a pic of the hinge.



They are welded to Rokmen corners.



1" pins



1" bronze bushings 2" square tube.
