Leaf Spring Failure

We had a rear axle passanger side leaf spring fail a few days ago on our TT enroute. Fortunately, we had pulled over for lunch and noticed a lean to the TT. There was no other damage. The mobile tech assumed it failed when we stopped. A repair was made with used parts, as nothing could be sourced locally for a few days. After traveling an additional 400 miles to our destination, I noticed the repaired leaf "slipping" slightly to the inside, about 3/4 inch. I was able to tap it back in place with a hammer. We have an 800 mile ride home. I am slightly concerned with the leaf movement. Of course I will keep an eye on it. Any thoughts and/or suggestions would be appreciated. Can an additional schackle bolt be adhered to minimize that movement?
My outreach to the mobile tech has received no response. At Myrtle Beach now, back to Buffalo on Sunday. Thank you.

    Yes, one leaf in the pack was slipping. A steel hose clamp is something easily accessible to me at the hardware store and about the extent of my mechanical abilities. I would not expect to be able to crank down on the bolts, as I know the guy mentioned using loctite on the connections. Not sure whether that is good or bad. We were stranded and he got us back on the road, so for the service, we are grateful!

    If you mean one leaf in the pack was slipping out of position... I would wrap it with a steel hose clamp at each end.

    Anytime a leaf spring is installed the clamp or U bolts need to be retorqued after few miles, sometimes repeatedly until stop moving.
    If spring moved in relation to axle, you have sheared the thru bolt.
