I'll do a video to describe on the setup I used and overall thoughts about it's handling.
My estimation on damage reports.
Throw the axon spur out its too thin and put a xenon in. Much better spur.
The upper camber links changed and there is less slop on the king pin ball. How ever they king pin. Ball cups are shorter and the turnbuckle is the same length. 26x4mm turnbuckles should solve that issue.
Other than that the car is durable and fast.

Yes, the Axon spur gear is delicate to say the least. Definitely worth putting in a different brand of spur gear for durability sake. The ''updated'' upper camber link ball and ball cup are no good, I reverted back to the Yokomo setup.

Check out my video on YouTube about other thoughts and opinions on the FXM!

I have 4x26mm Lunsford turnbuckles in stock at gripworksRC.com That should make the updated king pin balls and cups work. I will test it this weekend.

The turnbuckle won't remove the slop from the upper ball and cup.

There was no slop in the upper ball and cup. The ball cup is just too short. Therefore there wasn't enough thread I
Engagement. In the mean time I reverted back to the fx ball cups and king pins and have no issues with the slop. Car still works great.

You must have a unicorn!

Both the FX and FXM upper ball cup and ball had too much slop. But, if you say there is no slop, I would say you're one of the lucky ones.

Has anyone experienced the diff ball bearings seizing up on the shaft? Both my 3/8x1/4 flanged and 3/8x1/4 (enter bearing/closest to spur) bearings completely seized on the shaft. I had to forcibly remove(destroy) them. I discovered the problem after I noticed the shaft didn't spin/rotate as freely as it should. But, I did notice the FIT was extremely tight during the initial build!
Also, can someone recommend a strong/very durable replacement SPUR GEAR??

If the fit is extremely tight, I would just take some fine grit sandpaper and lightly remove some material. I had the same issue with my Associated 12R5.2. You can use a Panaracer spur gear or Yokomo's new spur gear.

When I first built my FX (about 12 months), the non flanged bearing was the wrong size. It wouldn't fit over the axle/shaft. The replacement was a perfect fit.
Hopefully you might just have some bad bearings.

I replaced the original steel rear axle with the carbon rear axle. This is a great improvement over the steel design.
With the steel axle, as you tighten the left wheel nut, it can put pressure on the left bearing as it pulls the hub against the bearing.

I use the 1:4x38 bearing then thrust bearing then spring washers
So

Thurstbeaing)()|nut

Use 3 spring washers for extra tension. It will stop the car from diffing out
