Source of binding was in the gearbox. To backup - I took the diff out and checked it. Bearing had minor rust (weird used car on carpet...anyhow) but was not source of binding, or the hub bearings. There was a lot of gear diff fluid around the rear of the car. Then I opened up the gearbox.
Bingo - It was full of diff fluid, almost like it exploded in there. Gears turned okay but were just resistant and slow. Fluid all over the bearings as well.
I'm in a bit of a pickle now. I think I need all new bearings for the gearbox because of this binding asap. because of the rust, i'll likely need ones for the hubs (minor surface rust that can be rubbed off though). Looks like I may as well buy a new bearing kit. Puts me about at the cost of buying new. Guess you win some lose some.
What would be the best way of cleaning all this residue and coagulated diff fluid combined with black grease? Can one clean the bearings? I'd like to try fixing this in the meantime as the bearings I need don't get to the shop until next weekend and I'd like to run the car for the time being. Can use those as backups too or just change them out later...
I did get some advice that Xray bearings are better for the long run then avid/schelle, if not getting ceramic so I'm inclined to do that. But someone also mentioned for a little more try to replace some of them with Kyosho if I'm already going to spend that kind of dough. Don't want to buy Avid as my track doesnt stock Avid and I want to buy from the track as they've been helping me with the car.
In any event, thought would update all and thanks for the help. Any suggestions regarding cleaning, refurbishment, bearings, rust, etc.?
thx!

Honestly at this stage I would just take everything apart and let all the parts and bearings (except maybe the o-rings from the diff) soak in wd40 overnight.

The only thing I have ever seen cut through silicone diff fluid with any effectiveness is VMP Naptha. Put it in a glass mason jar and use a tea ball
for any small parts.

Hello,
Can some help me to find the correct offset of
21mm hub for Xb2 in order to use AKA Evo Wheels?

I'd like to confirm if the evo/vtr type 2.4 wheel is any different than a standard 2.2 wheel on the Xray? Bought rear hexes to match associated offset. Evo/vtr/2.4mm vs 2.2mm should be fine regardless correct? Thx all for the help on this and all the above. Cheers
