So the Yukon wants attention. Anyone d.i.y. this? I guess I gotta grind the old one off and driveway weld the new one in place? Also anyone have the part #'s handy? I know I've seen them on here before but too aggravated to look..

Thanks Joseph but in addition to the parts you listed I need these as well. They need to be welded in.

Go to the GMPartsDirect.com site, enter your truck specs or VIN, and see if you can find that part, as well. Or, talk to the dealer.

In reality, your best bet may be to bring the truck to a local welder shop (exhaust shop, for instance), and let them fabricate and weld a piece to the truck. Should be easy peasy for them.

Repair Of Front SwayBar Frame Mount

Hi All I was asked to post this repair in here so others can see We have a 2007 Z71 with 85,000 miles that has served us well for many winters getting us around in bad storms and plowing our long driveway. Due to the liquid calcium chloride they have been using on the roads in NY, the underside...

This covers the swaybar bracket replacement with part numbers

So the new brackets don't have any threads in the holes..Im assuming the new bolts 11570934 make their own on the way in. GM calls the bolts "hexagon flange head tapping" bolts. Just wanted to check on here for verification.

"Tapping" is the operative word. Probably should be called "self-tapping."

Agreed

That makes me want to weld a nut plate in, instead of welding a new mount. (I drilled one bolt out crooked)
Though in @solli5pack's case, the mount looks all rusted out.

There is a factory retaining nut on the top but I assume it's welded to the frame?? If so, aligning the new mounts will be key so everything lines up.

 

[mikez71]

That nipple that gets threaded, becomes the retaining 'nut'.

Yes. There is no actual nut. Should be getting my new ones welded on next week.

Perfect setup to hold water and rot away....

 

[mikez71]

I guess the nipple nut should be better at not rusting on the threads vs a nut...

Maybe what we need is a drainage hole on that corner that gets welded between frame and front crossmember...

Yeah just like the top of the fuel tanks where the fuel pump sits. In recessed bowl with no drainage. Same thing happens to that eventually too.

I’ve started coating every new part I install that’s exposed to the elements with Blaster Surface Shield which is a lanolin based protective coating. It seems to be working well at preventing corrosion. I’d consider coating everything on the underside on a new truck based on some long term usage testimonials I’ve seen. The ship has sailed for the current rig.
