I dont have this car, but i'll try...
the things that *generally* sandwich the rear
differential and connect the suspension arms and
shocks are the "FD-18 REAR BULKHEAD"
The thing in the middle with the one shaft cup
pointing forward and the two cups on each side is
the differential. Its made up of the outer case:
FD-62 FINAL DIFF CASE CAST. This pack includes the
main bevel and pinion gears too.
Inside the diff is an internal set of small bevel
gears, often called 'spider gears' these are:
OT-028 DIFF GEAR SET
Tower has many of these parts in stock. First you
need the part # from kyosho's website, then enter
it in towers Search bar.
In my experience with my QRC, (which uses manyof
the same parts) This sounds like you may have
damaged your diff bevel or pinion gear. Its also
possible that you have a speck of dirt wedged into
one of the teeth of those gears. Take it apart and
closely examine the gears.
Another possibility is that you may have binding
in one of your swingshafts. (dogbones, halfshafts,
whatever you wanna call em) This commonly happens
when they run at too much of an angle - maybe you
jacked up the suspension a bit for more ground
clearance??
Also check eack bearing in the drive train.
Sometimes when bearings begin to come apart, they
jam now and then...Take the drivetrain apart and
check each bearing individually by spinning the
shaft that belongs in it.

This makes me suspect the dogbone and joint
between the rear diff and the center diff. If this
is worn or bent or full of dirt, you may get some
binding. Also check to make sure the chassis isnt
bent. If it is, the center and rear diffs may be
too close together and jamming the dogbone.
The good news is that most of these parts are
cheap and available. The bad news is that you have
some disassembly to do to find your problem!
Lemme know if ya need more help, Mike
