CV Axle Pin Problems
This isn't too common on Savages since few people run constant-velocity driveshafts, but it can be a real problem as you can tell by the pictures. Not something want to happen during a bash session or a race!
All that happened is the pin on my Hot Bodies axle came loose, but obviously bad things can happen. Worst-case, it'll come all the way out and get lost, then you're screwed until you get a replacement. Fortunately for me, mine didn't come ALL the way out, only far enough to start grinding on the TVP cross-brace as the shaft rotated, so I was able to re-use it.
The solution? Always threadlock the grub screw, naturally, but if possible install a second grub screw on the other side of the axle end, assuming the hole is there and tapped for it. The next step is to remove the pin and in the middle grind a shallow notch into which the the grub screw can register. Just be sure to have the pin rotated correctly as you slide it into the axle so the grub screw can contact the notch. The last thing to do is to find some heat-shrink tubing that's just larger than the outside diameter of the housing, cut it to length, and then shrink it down to really lock that pin into place. I did all these things and while the heat-shrink tubing finally fell off after a couple gallons of fuel went through the truck, the pin never came out.
