welding new rear bumper on

I am fabbing up a new rear bumper and I was going to weld it on. Of course it is right next to the gas tank. is that OK? I know how to weld but I have not welded on a vehicle before. also the piece of channel iron (cross member) ? should I weld the bumper to it or remove it? Thank you for your help.

Why wouldn't you just bolt it on? Of course I know nothing of such things, but it seems to me that bolting it on would be much better, so when you decide to change it, you can just unbolt it....

Agreed. If u can weld just weld on a bolt to the back of it and bolt it on. Never make something permanent unless u have to.
P.S.- by welding on a bolt I meant drill a hole cut off the bolt head and do a large spot weld then weld it on the other side. Much stronger

not a bad idea InfernoGirl, The previous owner welded some diamond plate on rear passenger side frame. to fix some rot no doubt. so there no holes there. I could drill some but then I will definitely have to remove the cross member? and I am not sure about the bolts that go up through the rubber washers into the body. is there a nut up there or does it screw into the body? I should say that I am new to having a jeep so I am not sure what to expect. Thank you for responding Tom

Do I remove the cross member? or leave it on? I am talking about the piece of steel that attaches to the body w/ bolts and also attaches to gas tank shield. Is that the cross member?

If that one looks patched why not go to a junkyard and yank one off a jeep there thats not patched and solid with the holes in it already

Cool bumper

The cross member is not patched. Its the rear frame rail. I guess that the cross member stays on no matter what? I don't want to bolt bumper to cross member it looks flimsy. But not sure how to install bumper with out cutting x-member. I am sure that I am missing something.

weld angle iron to the frame and cross member and drill holes thru it then bolt your bumper on by doing that you will tie the bumper into the frame it will be alot stronger but you will need to drop your gas tank to do it

Bumper

Thank you everyone for the advice. I once was blind but now I seeAfter reading the replies and looking at a couple of other wranglers. I see that the x-member needs to stay and how to bolt my new (soon to be fabricated) bumper to it. I am going to strengthen the x-member though because it does not look strong enough for recovery use the way it is. A little weld here and there. Again thank you I'm just a little S L O W
