Installing an AA fixed yoke on my 231...

...and I notice that I have some nice, DEEP, mill marks in some areas of the mating surfaces (main housing). I understand having a few small ones, but this doesn't seem right. My prior t-case leakage was coming from those areas. Is this normal? I'm planning on filling them in with JB, then sanding it down a little (to make a level surface...adding, not subtracting anything) after it cures and putting the case back together.

Also, what's a preferred RTV to use? I have black Permatex but it seems like I should have something different...and no, the dealer stuff isn't an option for me, unfortunately.

Thanks.

I'm assuming then that these mill marks were normal?

Yeah ,mine was the same way.Just make sure its clean/dry and lay a good layer of silicone down.Ive had mine apart several times and never any leaks!

I'm gonna fix it later on. My friend and I put it together and he was a little on the conservative side when he put the RTV on. It's actually leaking in a few places, happen to be where the mill marks are...again. lol I'm not worried at this point because I got the SYE in and it's no longer leaking out the slip yoke.

BTW, it drives GREAT with that short shaft in...and I 'cheated' and put a stock front driveshaft in (double cardan with 1310 ends, slip shaft). I need a little shimming in the rear, but the thing is 600% better than before. The length just happened to be correct for my amount of lift, so I figured why not put a front shaft in rear that's identical to my current front shaft? With them in abundant supply and cheap to rebuild I can carry one spare on the trail.

Thanks for the reply, BTW.

Only a few more weeks and I'm back on the trail. SWEET!
