Matrix/Morpheus jokes aside, what color Loctite do you use for a pinion grub screw? I thought I had a decent amount of blue on the grub screw. However after 6 or 7 runs the pinion slid off. Has anyone found red better?

I only use Loctite 242 and it holds up. You're on the right track regarding manufacturing residue. Give the gear and grub screw a cleaning with acetone or some other strong degreasing agent before you apply the Loctite and, as someone already pointed out, let it set up for 24 hours. Another underrated variable will be the tools you're using. Particularly with smaller hex drivers it pays dividends to not cheap out on your tools so you can torque them down properly without stripping them out. Wera and MIP make high quality bits that will save you a lot of grief. If you already have that taken care of, ignore the second half of this postI guess I should have added it was a new pinion and didn't drive the truck for a week. Maybe there was residue from manufacturing or just a fluke? I'll clean it up and try again.
I have MIP driver bits and bought the Corally tool set. I had to replace a few cheap drivers and was missing some tools/drivers. No more stripped screwsI only use Loctite 242 and it holds up.

Depending on what type of metal you are trying to secure with 242 you should be using loctite primer. 243 doesn't require a primer. The primer is a cleaning agent and adhesion promoter.Are you using blue 243? (Bottle is red, but it's blue type) There's a couple different types of blue. I believe the 243 is a step above the reg blue, but still not permanent like red

I have this, It's good stuff! Seems much stronger than blue but is still removable. I use a touch of heat to remove just in case though.I used below. I couldn't find a number 2xx on the bottle:
How about this stuff?:

243 is more oil resistant so yes it does work better. Still, need to clean everything with alcohol at the bare minimum to remove residual oils etc. from manufacturing.Are you using blue 243?
