I understand why many shops would walk away from this. Ask a Ford dealership, and would they say "new frame?"
You can weld on almost all passenger truck frames, there's nothing special about the steel. When you get into the bigger commercial/ cab and chassis trucks the frames are usually heat treated and generally shouldn't be welded on EXCEPT where the manufacturer says it's ok and you follow any specific procedures they have. If any shop told you that you need a new frame to fix this you better just leave and never deal with them again.

The correct way to fix it would be:

Get a new bracket or cut one off a junkyard truck, lift the bed, cut off old mount, weld on new mount, replace bed.

Or you can cut off/drill//knock out the old stud and just use an appropriate sized bolt.

I ask because I'm planning on buying the B&W 5th wheel hitch and ordered the truck with the 5th /goose prep.
The factory 5th wheel / gooseneck mount hitch plate does not interfere with the shock mounting bolts. The B&W unit interferes, as you can see in the OP photos. This is what the shock mounts look like on a truck with the factory 5th / goose prep. As you can see there is plenty of clearance because the plate is on the other side of the bed support rail.

The B&W hitch when installed blocks the passenger rear shock from being removed unless you disassemble the B&W hitch on the under side of the truck. B&W is aware of the problem and offers a sheet to explain how to disassemble the hitch. My issue is, I cant imagine what that may be like if you live in an area that uses salt or if the bolts over time somewhat seize. This is assuming that you do not have the factory hitch prep and are installing the B&W turn over ball hitch. In the original picture you can see how the bracket interferes with the removal of the shock.

if so you may need to remove the hitch portion and weld in a new bolt or maybe the stud cut off a junkyard donor truck

or google shock mounting stud, there are lots to choose from

https://www.speedwaymotors.com/Speed...Bolt,5485.html

welding there should not weaken the frame at all, but drilling it and thru bolting would also work, just make sure to use washers and lock nuts and don’t crush the shock bushing too tight.

I think I’ll go this route and thank you for the link it’s greatly appreciated. I’m no welder so I’ll try and steer away from that.
also thanks to everyone for voicing there opinion here it’s greatly appreciated.

I opted to drill the stud out and replace it with a grade 8 shock bolt. Fox sent me a steel bushing for the shock and it bolted up perfectly. I will never have an issue and I won’t need to disassemble a hitch that may or may not come apart after a few years. In hind sight I would buy the Ford hitch not the B&W.
do you by chance remember where you bought your bolt? And did I’ve got bilstein shocks with the rubber bushing, would the fox steel bushing be able to be placed into that or it only built for fox shocks? Thank you very much

Google search "Shock Mounting Stud" and you'll find tons of them that look just like the stud sticking out from that frame bracket.
Cut and drill the old one out, install one of the new ones you find. I would have it welded in by a competent welder, not just bolted in.

Anyone else ever had this occur any suggestions is greatly appreciated.



Picture I found online of what it looks like without the shock on it.
Surprised no one has mentioned the what appears to be 12 gauge romex holding the shock on the post.

This is why buying used trucks sucks.

It is hard to anticipate or discover every possible short cut that a previous owner has taken, or that was taken by a previous installer unbeknownst to the previous owner.

@Jorgem2 nailed the root cause of the short cut taken in this instance.

Well, we at least know the hack hitch job was done in early 2022 per the 12-2 Romex.

I agree with the other poster, I think whoever put the hitch in cut the bolt off. I don't see any shock shearing off that bolt. That guy would need a good hiding place if this was my truck.

I don't think it was whoever put the hitch on.

Rather, it was whoever put the aftermarket shock on.

The B&W hitch was in the way of the OEM shock removal.

Clearly the shock bolt was cut off with a reciprocating saw AFTER the B&W hitch was already installed, because we see the witness marks of the cutting action on the B&W cross rail (creating a stress riser / weak point on that cross rail that supports the hitch).

The shock mount is not in the way of the B&W hitch installation. Instead, the B&W hitch installation is in the way of the removal and replacement of that rear shock. The shock shown by the OP is an aftermarket shock, which suggests that the shock mount stud was cut to remove the OEM shock, as the B&W hitch interfered with pulling the OEM shock off of the stud.

I have read, but have not confirmed, that B&W has since changed the design of their cross rails for this application, to avoid this all too commonly reported problem.

I’d cut it flush.
Drill or grind out a hole.
Weld on a flange nut flange facing inboard.
Then use a shouldered bolt through the shock.

Done.

And yes, single shear is stupid.

That's the HD romex, standard "out of options" romex is 14-2 for sure.
