I think Lumpy Grits is on to something.
I used Warn Premiums for years, but I've noticed Mile Marker is better built and works SOLIDLY...
Lockouts are usually a poor install job...
Specifically, people don't clean the threaded mounting holes out correctly,
Leave a bunch of 'RTV' ('Gasket Maker') in the holes,
Don't clean out the rust/crud,
And the bolts back out...
First off, Clean the holes out THROUGHLY, get a pick in there and make sure there isn't any RTV hiding in the bottom of the holes.
Then use a tap and clean the threads out,
Then use a good, CLEAN EVAPORATING solvent in the hole so your thread locker will do it's job...
USE THE CORRECT LENGTH BOLT!
So many people I see use bolts that are too long, and try to make them fit with washers/lock washers,
Or they use bolts that are too short and barely get into the threads.
USE NEW BOLTS!
Use a good quality bolt, one with full engagement threads.
Worn out bolts have rounded over threads and will never stay tight.
Use a 'Blue' thread locker on clean bolts and clean holes.
I've never had one back out with clean, sharp threads and thread locker.
For an extra measure of security, use lock washers or locking tabs to keep that properly installed bolt from backing out with use.
Not that this will have a lot to do with an internal swap, but guys getting this thread in a search might find it informative...
