Front Knuckle - Left — Tesla OE 2188311-00-A / 2188311-00-B

Genuine Tesla OEM front steering knuckle / upright — supplied as the newer Model Y "Juniper" casting, OE 2188311. Left side. The factory confirms it is interchangeable with and replaces the earlier Model Y knuckle (OE 1188311), so it fits both the 2025+ Model Y Juniper and the Model Y. Carries the wheel bearing and hub; replaced after an impact or hard curb strike. Locally stocked in Greater Vancouver.

Fits Tesla Model Y Juniper (Feb 2025–) and Model Y (Jan 2020 – Jan 2025).

Tesla revises the suffix on this number over time — 2188311 is the base number and identifies the part position; the trailing letters are Tesla's own revision level. We carry it as 2188311-00-A and 2188311-00-B. If your estimate shows a different suffix on base number 2188311, send us the number and we will confirm the revision before shipping.
