VMG DIFF  FIX
RACE IT DON'T BREAK IT!!
  Ok here I will show you how to fix the VMG  diff once and for all!

Note:  I will try to explain this as simple  as possible!
This pic shows  what plagues the VMG diff this is an almost new car!
notice by red spot plastic rotating on plastic not lubed from factory fusing together NOT TOO GOOD, as you can see the white powder!!
I will show you how to  properly lube and assemble the axle later..
First you need to take the diff out of your car it will simply pull apart like shown in this picture.
I used Parma  homeset lube it works great.. But for all out
performance i suggest cleaning  out the diff and get all the
grease that was in there out if there was any and use
Team Associated Black Grease # 6588 This is used for
there RC kits  It is a very sticky grease and it will make
your diff work much better than  if lubed with silicone
type grease.. But the Parma grease also works  nice!
Grease all gears as shown!
ALSO add a drop  of oil to each bevel gear where
the tiny metal pin goes through them both!
Very  important!!
You can substitute the grease and use a few drops of oil
on  this part if you wish.. But i like using grease here!
Grease behind the bevel  gear on the plastic shaft!
To do this simply pull the diff casing away  towards
the tire as shown..Put a nice coat of lube on it!!
DO THIS ON BOTH SIDES OF THE  DIFF!!
Very  Important!!
You can substitute the grease and use a few drops of oil
on  this part if you wish.. But i like using grease here also!
Pull the bushing  away from the diff case as far as possible
as shown in the pic.. Now put  a nice amount of grease here!
DO THIS ON  BOTH SIDES OF THE DIFF!!
Now put like  2 drops of oil on the axle here
making sure it drips down into the  bushing!
DO THIS ;ON BOTH SIDES OF  THE DIFF!!
Now clean your  diff casing before the glue job!
Clean your diff casing with a cleaner  rubbing alcohol works
fine here! make sure you clean all the way around the 
areas marked with the  red dot!
Here is the  diff assembled correctly!
(not glued together yet)
After you put the  diff together properly go around the
diffs seams on both sides where you  snapped it back together
with a light bead of CA glue (super  glue) making sure to
cover the seams.. I use a tooth pic to spread it  smooth.
this holds everything together and tight!
Apply a generous amount of goop glue on bushings by
using a pin trying to go all the way around all bushings on all the
sides of the bushing where it snaps in place the 4 spots
as  shown this holds it all together tightly and stops flex..I use the goop glue
because it can also be  removed if needed..
LOOK AT  PHOTOS BELOW!
DON'T BE AFRAID TO PUT THE GLUE ON!!
as you  can see i use a generous amount!

be sure not to glue the bushing to the  gear pumpkin
Now before you put the chassis together apply  a thin bead of goop glue as shown here below.
PLEASE DO STEPS LISTED  BELLOW THIS FIRST!!
Make sure  to go right across the edge of motor with the glue
this will help stiffen her up!
A MUST DO!!
Here i use grease and put it on all  areas shown in red.
Make sure to put a coat of grease right where the 
guide  wires rub on the axle!!
The VMG magnet flop syndrome fix!
Here i put a crumpled  tiny piece of paper down
into the magnet holder I put just enough so  that
when i push the magnet back in it just raises up
a hair out of the  holder this makes your magnet stay
down where it needs to be ! IT WORKS GREAT!
KEEP IT OILED PROPERLY AND KEEP IT FAST!
Oil by  these spots marked above periodically by
simply adding a few drops of  oil to them.
Oil the gears, the axle where it goes through
the bushing and  also in the side of bushing
  that hits up against the diff housing
NOW put the car back together oil the gears and let all the glue  dry..
Now you will see your VMG FLY; like never  before!!
