I think its a 54mm.  Its actually the same size as the front wheel bearings on the stock yota solid axles.  My socket is 3/8 drive so i snapped off the ratchet trying to break the bolt lose.  haha

I should have a 2 1/8" socket and multiplier. I'll look and let you know

Nice👍 when doing that do a third of the turn method. We do this at work some times and is a fairly accurate way to torque if you don't have anything.

That's good to know.  It's honestly very hard to get much more turn on the nut even with the mini sledge hammer.

First off, Merry Christmas to everyone!  I hope everyone is getting to spend time with their families and loved ones for the holidays!

Update:

I finally got around to getting all of the portal boxes replaced.  But in order to make a Veteran's day ride to Morris Mountain, i had to skip the painting of the front caliper mounts.  So, I'm addressing that now.  When it came time to replace the front portal boxes, i discovered that the driver front caliper was leaking around all 4 pistons.  I've never seen a caliper do that and especially not one that was new.



I exchanged the caliper at the local parts store but ran into an issue.  It appears that the casting for the calipers varies slightly between calipers.  Enough so, that i can't use the mounts i already built for the calipers.  This is a problem because i already had to grind the backside of the caliper to clear the wheel as it was before, so this will be even worse if i have to pull the top of the caliper further away from the portal box.  Plus, this will pull the pads away from the rotors and cause them to wear unevenly.

You can see in the below picture, that the banjo bolt hits the portal box before the caliper will bolt will go in.  About a 1/4" off actually.



Here are my thoughts on how to address this for good.  The main point for me to run these calipers was so that if i were to ever have an issue with a caliper while out wheeling, i could exchange one at the local parts store.  But this has proven to not be as easy as i had hoped with the different castings.  Plus, I've had issues getting them to stop leaking at the banjo between the washer and the caliper and/or banjo fitting. 

To resolve this for good, I've talked to a few friends around here and we've all come up with the best way to fix it.  I'm gonna run stock replacement calipers for the same corvette but from Wilwood.  These are definitely more expensive but I'm tired of fighting with the stock calipers and getting them to fit and not leak.  The Wilwood calipers will resolve both of my issues here.  The brake line inlet is no longer near the portal box.  Instead, they are at the bottom of the caliper.  This will allow me to bolt them onto the caliper mounts without any portal box interference.  Secondly, they don't use banjos for the brake fluid inlet.  Instead, they have an 1/8" npt fitting.  This will allow me to get an adapter for 1/8" npt to -3 AN and directly connect my -3 AN lines to the calipers.  No more leaky leaky for the brake lines.  So, I'm gonna replace the front 2 for now then later replace the back 2.

One of the other issues that i wanted to address, was the leaking Dana 300.  Since it's flipped upside down, it tends to leak out of the shift rail seals.  So, i found a guy that makes an aluminum seal retainer since the stock one was missing from my tcase when i bought it.  I then doubled up the shift rail seals.  I'm also adjusting the linkage some, so that the shift levers don't hit the cutting brake levers anymore.  I'm not sure if this has been the reason why the rear output would pop out of low range while descending down some hills.  I'll find out the next time i go wheeling.



When performing a nut and bolt check, i noticed that jamb nuts backed off for the tie rods.  When i got the tie rod kit from PSC, the tub adapters didn't have a hex head on it so that i could put a wrench on it to fully tighten the jam nuts.  I ordered some aluminum tie rods from Wide Open Designs to resolve this.





Now that I've gotten most of the quirks addressed, i wanted to go ahead and recenter my wheels to get rid of the 1.5" wheel spacers.  With the new backspacing, the overall truck width will grow from the 92" currently, to about 96".  I ordered the centers from Stazworks but while i wait for them to arrive, i went ahead and took the spare wheel plus my 2 front wheels apart and brought them to my buddy that has a plasma cutter.  I'll post up some photos of the finished product once i get the wheel centers. 



Here are the PVC inserts that i use from Trail Worthy Fab.



I'll end this update with a few photos a local photographer took while with a few friends while we were out at a local park playing around.
