Adjust Shim Assembly Note

WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

Assemble the differential carrier to the SSTs .
Assemble the spacer to the differential carrier.
Stack the side bearing outer race and gear case component on the surface plate as indicated in the figure, and measure the height using a caliper and a ruler. This is value A.

The combined thickness of the left and right adjusting shims is obtained by the following formula.
C ₁ = B - A + 0.16 mm {0.0063 in}

C ₂ = B - A + 0.25 mm {0.0098 in}
If the combined thickness of the previously installed adjusting shims is between C1 and C2, use the shims as they are.

If the combined thickness of the previously installed adjusting shims is not between C1 and C2, or if the adjusting shims have to be replaced, select two appropriate adjusting shims from the chart below. Adjusting shim thickness

CAUTION:

If adjusting shims are to be reused, do not mix up the left and right shims.
Do not mix up the left and right side bearing outer races and spacers.

Assemble the differential and bearing outer race to the differential carrier.
Tap the selected adjusting shim between the spacer and the bearing race with a plastic hammer.
