Rear Shock Mounts

[jagular7]

I've got a 05 F350 CC C&C. Its rear shock mounts are u-bolted to the axle. There is a small round stub welded to the axle tube and the bracket sets against the flat part of the stub. The u-bolt then holds the bracket against the stub. Shock then gets mounted.

Somehow, the u-bolt loosens and the u-bolt punctures a hole in the shock making it leak.

I'm looking for ideas to remedy the situation. Thought of welding the brackets to the axle or welding the ubolt to the axle. Any other?

Weld or use Red loctight, I've never had them loosen on any truck I've worked on??
