Rear Bumper Weld Nuts Broke


Recommended Posts

Hey guys,

All of the weld nuts inside the frame rail are broke off in the back of my Comanche. What's the best approach to fix this? Anything easier than pulling the whole bed off? It's a 99% rust free AZ MJ so I don't know how the PO managed to break every single one. Thanks

I had one that did that . I used an air chisel to pop the welded nuts and then used a nut held in a wrench with tape and tightened all the bolts . I started with the furthest one and worked towards the rear of the truck 

 

Tape to hold the nut in the wrench I like that. I'll try that when I get a chance. Some good lock nuts should work

Hey man that's a nice Comanche you got there! I moved to Tucson in 2016 and finally picked up a manche recently. Being from the Northeast I still lose my mind every time I see a rust free one.

I was under the truck crawling around doing a bi-annual inspection a few years ago and spotted one of the bed bolts was only screwed in about half way. Figured it came off the assembly line like that. Got a socket and tried to tighten it and the weld nut broke free and now just spins. I'll have to check again, but I didn't see a way to get an air chisel in there...

Thanks. And yah, I know the feeling. Moved out here from NY a few years ago. Couldn't find a decent MJ till I moved out west.

Yeah , never had that problem before . I guess there's still 7 other bolts holding it on , leave it alone until you have to pull the bed for some reason?

Yep, that's what I plan on doing.  :thumbsup:
