So I love my rear bumper set up made by Luke at 4x4 labs. I was getting a shake with the tire carrier left and right that was bothering me as I watched the tire in the rear view mirror. This was only at highway speed and at random times. I solved the issue with my high lift jack and was able to support the arm by triangulation. It was simply by drilling a hole and bolting it to the 2x2. Luke makes the attachment for the high lift already behind the tire. Below are pictures.

I like it.
Any good ideas for reducing front-to-back movement?

Yeah, I don't get any side to side, only front to back shaking. This might help that as well, though. Might have to break out the drill.
I was considering stacking then stitch welding another piece of 2x2 on top between the hinge and tire carrier to stiffen things up.
Has anyone ever had the tyre carrier fracture as result from the vibration?

I asked Luke that same question. His bumpers are really well made and his welds are good too. He has never heard of his bumpers failing from any purchasee that he has built. That being said, I think if a bumper was built DIY and the builder made crappy welds then there obviously would be a much greater chance that failure could occur. This thread wasn't made to be negative of the quality of 4x4labs. I would definitely purchase again.
Gotta agree. I couldn't be happier with my rear swing out. Can't say I have ever noticed it vibrating at all. Like you say the welds and design (which encompasses triangulation support for the carrier arm) are absolutely solid.
I had a buddy ditch the 2x2 and go 2x3 on the arms. Feels more solid than mine. I like the hilift idea though. Nice work.
mine One Dont Have any vibration even on very high speed with 37" rear spare wheel.
by the way Highlift jack idea is good ..

I have mine on the left(DS) and use it to get up to the rear deck.
I'm in the Clydesdale class, and I swing my lard ass up by pulling on the top of the High Lift and stepping with one foot just above the latch and then stomping on the deck and pulling up. It never really moves too bad unless the highway splits are just at the right harmonic, or whomping the dunes in Pismo. The washboard in Death valley got it going good though, but those roads get everything going loose.
I know of one guy who welded a .25" thick tube inside on the shaft side and then had his buddy wrap it with a pipe wrench and twist it by standing on it, then tacked it into the end plate. Like a torsion tube. It worked awesome.
As for the strength of these things, I've smacked mine into granite each summer on the Rubicon, and a tree or two, it's all smashed, but still works great.
I'm looking into adding a table to the back edge of the tank basket like one of those slide in types from a RV so I can put it away when things get dirty and then use it in camp for a chips and salsa deck.
I didn't weld mine, nor have I ever adjusted it, I should be able to remove the dust cap and tighten up a nut on the spindle right?

Does anyone know the size of that stud on the back of the tire carrier that holds the Hi-Lift jack? Thread Pitch? Just wondering if Hi-Lift's lock will work on that bolt.
the thread spacing your lugnut is
you use a lugnut from a wheel
Ahhhh! I wondered that as I was looking at it.
Mine flexes quite a bit due to the design. I drove 1200 miles from wisconsin to nc with a about 400lbs in a basket(a suzuki samurai g13a motor and parts) hanging on the swing via the receiver mounted in the middle of the ladder with no problems. Labs builds a stout arm. I have no stress fractures, welded all with a 180amp lincoln. You guys worry too much... 
Nice job
