Subaru Legacy BN/BS (2015-2019) Service Manual: Adjustment

1. Measure depth “A” from the ST upper face to the ball bearing catch surface.

2. Measure height “B” from the ST to the end of the ball bearing outer ring.

3. Obtain the thickness of shim using the following formula to select none to two shims.

T mm = (A − 15) − (B + 15) − (0.05 — 0.25)

[T in = (A − 0.591) − (B + 0.591) − (0.002 — 0.01)]

T: Shim thickness

A: Depth from the ST upper face to the ball bearing catch surface

B: Height from the ST to the end of the ball bearing outer ring

15 mm (0.591 in): Thickness of ST

0.05 — 0.25 mm (0.002 — 0.01 in): Clearance
