Mevotech Supreme Wheel Bearing and Hub Assembly P/N:H515047
Silence a growling, humming rear wheel and keep the wheel spinning true with the Mevotech Supreme Rear Wheel Bearing and Hub Assembly (MB86317). If a worn rear hub is behind the noise, this assembly drops in as a direct-fit replacement for many Lexus models, among them the 2016-2023 Lexus RC300, 2015-2023 Lexus RC350 and 2016-2021 Lexus IS300. See the "Vehicles it fits" section for the full list.
This rear hub assembly carries the wheel bearing, supports the wheel and lets it rotate. Signs this wheel bearing may need replacing include a cyclic humming or growling that changes with speed or cornering, plus wheel play or roughness when the wheel is spun. Diagnose the cause before replacing, since other parts can produce similar noise.

Does it come pre-greased and sealed?
Yes — it is pre-filled with premium lubricant that withstands high temperature and extreme pressure, resists corrosion and reduces friction, and uses a multi-point seal to keep contaminants out.
Should I replace both sides at once?
