I hope you don't mind me stealing this idea so I can have mine stay open when I'm parked off-level.
I'll play.....some here may not frequent the 4Runner section, as I have posted in there already.
I turned down a rather large stud to 1.5" and threaded the end a bit. Made a sleeve out of an even larger stud, and a couple bronze bushings for the top and bottom.
My closing latch is real sophisticated.....
So far so good, once it was pumped fill of grease it made the hinge smoother and easier to swing.
Not sure what the breaking point will be, as I can support my whole body on this thing when it swings out, but the whole 4Runner leans quite nicely when it's open just with the weight of the tire.
Only downside so far is that my latch pin makes for some rattling when driving. It's not noticeable going down the highway and even around town, there are so many other noises from the vehicle that the pin rattling doesn't bother me.
Well done on your execution. The bronze bushing is a great addition.
In general with greaseable bushing, moreover those exposed to direct sun, is to check or pump more frequently. The grease (depending on selection) will more easily heat up and flow out.
For your latch, you did a great thing capturing in double shear the motion that is fore/aft (open/close) direction. That is an important load direction. The largest amount of forces are generated in the vertical direction. Since you have the gaps there on the end, I highly suggest you do a full capture. Pretty simple with how you already are and basically just add material to shim the bottom (mostly) and top such that you end up with a 1/16" gap. This will give you full capture in the vertical direction such that it's a rigid connection all across now and into the bumper. Staying currently will eventually fatigue your welds and the nice spindle you made. Bronze may go first b/c of being much softer.
I get what you're saying about supporting the latching end. I was hoping that if I add some shims on the lower side to keep the whole thing nice and tight, that the rattling would also be dealt with.....well most of it, I think the pin will still rattle a little.
Just wasn't sure if I should weld a block of steel in there with a little bit of a wedge shape to it, or maybe use something softer that can be replaceable if it wears out.....

Mine is working great. I built my arm a little light - I used 2X2" 1/8" tubing so it flexes a bit. I put a piece of angle on the latch side for support and it's doing fine. It's been on there for over 2 years.
Here it is before powder-coating, to show some details.
Nice looking bumper! And thanks, just placed my order with McMaster. Also,what is the wall thickness of the 2" tube you are using? And what kind of latch are you using? looks nice and beefy. Thanks for the info!
