Tom.......

I have had some issues with the screws in the front Hub also.......But only after the truck had a lot of Hours on the Chassis......
Plus,,,,I am REALLY hard on the truck (you've seen the Videos).....Lol
I lost a few screws before I realized what was happening. The screws fell out and then I hit a bump an the whole front Hub came apart.
I used GOOP on the threads and then a bit of GOOP on the head of the screw,,,,,to help hold them in. So far, so good.

Those Hub Screws WILL back out if you dont inspect regularly.......I have also RIPPED those screws out after Hard Landings from my Himoto Ramp,,,,,But I consider that to be ABUSE,,,,rather than normal Wear and Tear......

If the front hub assembly is constantly coming loose, then it is worn,,,,,and may be time for some replacement parts.....
