Installation summary

Installation of this Fall-Line Motorsports spherical bearing set requires advanced DIY skills and is best tackled by experienced mechanics equipped with specialized spring perch tools and a hydraulic press to remove the factory rubber bushings from the rear upper control arms. A complete post-installation four-wheel alignment is mandatory, along with any necessary ride height adjustments if your vehicle is equipped with coiler suspension. The most critical factor to watch out for during the assembly of the CNC-machined stainless steel housings and spiral locks is ensuring the bearings are pressed squarely to avoid damaging the precision components, while also preparing the driver for a noticeable increase in cabin noise, vibration, and harshness once the job is complete.
