Front bumper issues

Ok. I've got a 2000 TJ with a SB XRC front bumper. I plan to bolt a 10k lb winch to it. I do not trust the 6 factory bolt locations holding the bumper on. Especially since I had to drill out the holes in the bumper to mount it since Smittybilt was about a half inch off on their measurements. I was thinking about just welding it on. I know its a more permeant solutions but I feel it would be stronger than the drilled out holes in the bumper. Thoughts?

SB usually doesn't get that close. You must have gotten one built on Wednesday.

NO do NOT weld that winch on, that would be very dangerous and an improper way of mounting a winch.

The winch is not bolted to the bumper anyway, its mounting bolts only pass through the bumper to the threaded inserts in the frame below the bumper. So a winch is actually bolted to the frame below, not to the bumper at all. The bumper doesn't even have to be there to mount a winch.

Finally, it's only the two pairs of the front-most bolts that hold the winch (and bumper). That rear bolt is nothing more than a sheet metal screw, it's not holding anything structurally. The winch mounting plate will (should) come with four Grade 5 bolts which thread down through the bumper and into the frame, those will be what actually holds the winch (and bumper) in place.

I read it as he wants to weld the bumper to the frame not the winch to the bumper

Never seen a winch with six bolt mount so pretty sure he is asking about welding his bumper on

Yes, I was thinking of welding the bumper to the frame. And I'm not sure how the winch bolts to the frame when the ends of the frame are wider than the winch and there's no crossmember.

You need a winch plate. The plate will connect to six points in the frame. It does not connect to the bumper, but does use the bolts that hold on the bumper.

Winch mounting plates don't connect to six points on the frame, they only connect to four structural points on the frame... the same four points that the top four bumper bolts connect to. Points 5 and 6 are at the rear and they are just light-duty sheet metal screws which aren't structural. Give a little too much oomph to those two rear-most sheet metal screws and they'll strip right out.

I am absolutely 100% positive. The rear bolt does thread into the frame rail but it took very little force for me to strip its smaller diameter insert out when I was tightening it to install my first winch years ago. It's strong enough to hold the antiswaybar bracket in place and that's it. Notice that they're not 1/2x13 Grade 5 bolts like the front two pairs of bolts are. The Mopar parts manual describes the rear screw as a M10x1.50x35 screw swaybar retainer.

That's how mine connected. 6 points. Now I have a bumper with a winch mount on it, but the top of the bumper used the same 6 points. The last two being the bolt that goes through the sway bar bushing.

Correct. It is merely there to keep the swaybar bracket snug and to assist in maintaining a level plate. Thusly...

Agree smaller and weaker but not just a sheet metal screw as referred to in earlier post
