13x16x0.1mm Diff shim
Note: TKR1222 and TKR1226 Shims - The gear mesh should be tight without any binding. TKR1226 should
always be installed. Then test fitment of the diff with both TKR1222 shims on the gear-side of the diff. If the diff
turns freely without binding, continue to next step. If the diff binds and does not turn freely (it will make a
grinding or crunching sound when spun), remove one TKR1222 shim from the gear side and install it onto the
other side of the diff. Reassemble and test the mesh again. If it is still binding, remove the second TKR1222 shim
from the gear side and install it onto the other side of the diff. When you are satisfied that you have the best
gear mesh possible continue to the next step. You may end up using only one shim on the gear side.
