Beck/Arnley Suspension Strut Mount P/N:101-8639
Keep the front suspension quiet and properly located with the Beck/Arnley Suspension Strut Mount 101-8239 (also written 1018239). It installs at the top of the front strut as a direct-fit replacement for the 2010-2015 Lexus RX350 and 2010-2015 Lexus RX450H, anchoring the strut to the body while isolating road vibration and helping the strut travel and pivot smoothly. Beck/Arnley engineers its parts to match OE form, fit, and function for foreign-nameplate applications, so this front mount drops into the factory location.
Worn strut mounts can show up as clunking or knocking over bumps, noise or binding when turning, and added vibration through the chassis. If a failed front strut mount is the cause of those signs, this replaces it. Strut mounts wear on both sides — inspect and, where needed, replace them as a pair for balanced ride and handling.
