I seem to be missing one bolt and nut on my rear skid plate on my H3. Only problem is I do not see any threading on the frame bar connected to the truck.

any ideas how to fix?

How would you use the clip-on U-nut 11561740? That cross-member is enclosed, right?

You might have to tack weld a nut in there.

 

 

That arrangement is for the early H3's, I suppose. My 2010 doesn't have U-nuts, the nut flange on the passenger side, or the "H3" in the front shield .

The OP didn't state year model... Even if he didn't originally have a U-nut, maybe he could still wedge one in there.

Tom, I have a box of M8 U-nuts, if want a few.

 

Drill through that hole and out the top of the crossmember and use a long grade 8 bolt, washers and nut.
Iif there isn't a nut welded inside.

 

Every H3 I have ever seen uses the U nut clip for the front splash and oil pan skids.

 

33° & raining, this is all I will offer (only removed bolt on drivers side). You can check yourself when you remove the oil pan skid plate. Now have to go and dry myself.

 

Just noticed something while helping another member: You can see the U-Nuts in the video:

 

Interesting. My 2009 does not use U nuts on the differential support cross member, but has nuts welded inside the support. At some point before I bought it, some ham-fisted "mechanic" had cross threaded the bolt into the nut, and snapped the nut welds inside the cross member. I had to cut the bolt head off and push what was left up into the cross member to fix it - there was definitely no U nut on mine!

I used Tainter's recommend fix - drill through to the top of the crossmember and drop a long grade 8 bolt down from the top with washer and self-locking nut at the bottom.
