Carrier-adjustment shims required: Needed to set preload and backlash correctly.
Shims let you: Dial factory backlash, center the ring gear for a clean contact pattern, and eliminate whine/heat/premature wear.
TIP: We stock shim packs in 0.1 mm steps to fine-tune preload and backlash without chasing OEM spacers.
Watch before you wrench: Our 8-minute video covers bearing pressing, backlash measurement (dial indicator), shim selection, and contact-pattern checks with marking compound.
