Learn me: Loctite 660

I know that Loctite makes a bunch of stuff that is basically pure magic, but I just heard about Loctite 660 High Strength Retaining Compound aka Quick Metal, Press Fit Repair for the first time about 7 minutes ago.  This sounds like it's too good to be true, but it also sounds like it's cheap and easy enough to try.  Has anyone used this stuff?  Will it really do what I need it to do?

Here's what I've got:  On my first gen Neon, I had A1CVTECH make me some axles with stupid-strong CV joints in them.  In order to accommodate those axle stubs, though, they had to hog out my wheel hubs.  I sent them a brand new set of Timken hubs, they did the needful, and all was awesome.  RIght now, however, I have a very little bit of looseness in the left wheel and I just had the right hub apart and my mark I finger measuring device seems to indicate that the right hub is no longer quite as thick as it used to be.  I'm probably looking at $400+ to have them take three new hubs and hog them out for me (replace both plus add a spare for the shelf) or probably $200+ to see if a local machine shop could spray weld some material on there and turn them back down.  I haven't actually measured the hubs yet, but my gut is that it's under .5 mm too small.

In the below picture, you can see the hub sitting upside-down.  That tapered-looking ring that's on it is part of the wheel bearing and typically has to be removed with a puller.  I needed almost no effort at all with said puller to pop that ring off.  Like so little effort I never had to put a tool on the end of the puller, just turning its little bolt by hand was enough to get that ring loose.

The Loctite appears to be about $20 for a little bottle and claims to be "Ideal for repairing worn parts without remachining" and "Enables re-use of worn bearing seats, keys, splines or tapers". 

So what's the skinny on this?  Snake oil?  Sure thing?  Great product, but not for this job?  I'd say that if it has at least a 50/50 shot of taking the play out of the hub, I'm down to try it.

I have used it for the same purpose you're looking at.  My white Quantum had worn out hubs, I used it there, no problems.  Pressing them back out is a pain.

Fwiw, I stripped a splined hole for a pivot piece on my aluminum floor jack and the 660 worked perfectly. 

Alright then!  I ordered up a bottle and I'll get a couple new wheel bearings on the way.

It works great as long as both surfaces are clean and a close slip fit. Actually used in some engineering applications where you can only achieve a slip or light press because of material or depth of needed interference, but want the axial or torsional capacity of a heavier press fit. Getting it apart is a pain.

IIRC is is good up to a .010" gap.

I had fall out loose bearings on customer cars that this fixed, not just mine.  Noisy bearings eat that surface on the hub by whatever mechanism.l

The Loctite datasheets are excellent and I've never had one of their products not perform like the datasheet said it would so that's where I go first for application questions.

Used it for crank keyway repair on an early 1.6 Miata.  It worked, so worth the $$, I guess.  

I used some green on my Harley small end bearing when the piston pin grabbed and spun the small end bearing.  Just clean everything well and when you press parts back together the loctite sets up, so don't mess around.
