I keep loosing upper fender bolt
I keep loosing my upper right fender bolt and spacers by the windshield. It takes a month or 2 to loose them but am Leary about using lock tite in case I have to remove the fender in the future. I had to replace weld nut on my other truck and is was not fun when the bolt started twisting the nut on the body

Re: I keep loosing upper fender bolt
We built about 15 million squarebodies (so about 30 million fender attachments) and I have never heard of this phenomenon before.
You might want to look at the rest of the attachments and see if something else is causing this (ie, loose or bad radiator support cushions, other loose attachments or maybe too many shims at that location, etc). In any case - I would think a little blue Loctite would be ok. K

Re: I keep loosing upper fender bolt
I've lost a few on my dually as well. I always no it because the truck starts creaking really bad over bumps all of a sudden. Sure enough, each time it happens, the bolt is missing again.

Re: I keep loosing upper fender bolt

A good cross-thread beats locktite every time.

Re: I keep loosing upper fender bolt
If you are worried about spinning another weld nut, put the loctite on the nut head and shims. Not as secure but might be enough.

Re: I keep loosing upper fender bolt
Thread a piece of copper wire in with the bolt. The wire will meld into the threads and stay tight.

Re: I keep loosing upper fender bolt
Nothing wrong with blue loctite....or maybe a lock washer under bolt?

Re: I keep loosing upper fender bolt
The only things I could think that "over time" would cause this is:
1. Not having a bolt at the bottom of the fender under the cab, or a rusted fender that cant be secured. 2. A bent fender that the door hits when opening and closing. 3. Tires that rub the fenders when turning or going through dips and vibrate the fenders with the tread. 4. Off-roading on washboard roads. 5. Excessive shopping cart bashing at the local mall.

Re: I keep loosing upper fender bolt
a coating of solder on the threads works great, add a piece of thin copper wire if the fit is very loose.

Re: I keep loosing upper fender bolt
Any way to safety wire it?....drill a hole thru the head...tighten bolt ...run wire thru hole and fasten to something

Re: I keep loosing upper fender bolt
Well, if your bolt is loose then you may lose it

Re: I keep loosing upper fender bolt
My guess is you have a vibration problem you may not feel but your bolt and fender are feeling it, that’s why they keep vibrating out.
Don’t put a bandaid on your knee when the cut is on your finger. Rather than patch the problem, I would look at trying to solve the issue. |
