I tried to take my back wheels off
It is like they are sized on
The first time I undid one the bearing came with it
I did it back in and then did it again the wheel came out
But was still. Tite on the bolt both wheels are the same
Thanks mike

Yep, your bearings are rusted onto the bolt. You can either try to get them apart or replace the bolts and bearings. Ride more if you can!

I got them off
one bolt was seized on
can I put on some Anti-Seize compound
on the bolt ? or will the bolt come undone
thanks mike

Stainless on stainless will electrolytically weld parts together eventually. Copaslip can help prevent that. If you have different metals attaching themselves, it's just rust. A very thin film of grease between the bearing and bolt (wiped on inner diameter of bearing might prevent this from happening again.

this is unrelated but my bolt on the left side loosens almost every ride. It's the one where the wheel is trying to turn the bolt in the counter clockwise direction obviously, but is it a good idea to put thread lock on that bolt?

My first buggies only had a bolt that went through the wheel and tightened into the axle. Now I use stub axles like Popeye the Welder uses, with threaded rod going into the axle, a jam nut that tightens it into place, then a nyloc nut to hold the wheel on. I've never seen a nyloc come loose if the nylon was engaged. This scenario allows you to tighten the stub into the axle as tight as you want and then rely on the nyloc to hold your optimally tightened wheel in place. This would work on virtually any buggy.

A way to do this with off the shelf items would be to use bolts and a jam nut. You would get the wheel as tight as you can without binding the bearings up and then really tighten the jam nut into the axle end. Make sure you have enough thread engagement (I'd guess 1.5 times bolt diameter minimum) into the axle.

If you use thread locker to stop vibration issues then you need to know there are different grades for small and large bolts etc.
Make sure you use a grade that can be removed with hand tools and does not require heat.
You can often get product cheap which is "out of date" but will be fine for another decade or 2 on eBay.
