SCITOO Front Suspension Kit for Toyota Corolla (2009–2019) — 10pc lower ball joints, tie rods, sway bar links & rack boots

This SCITOO front suspension kit groups the wear items drivers commonly replace together to restore steering precision and front-end stability on compatible Toyota Corolla years. Each part arrives pre-greased where applicable and is engineered to match OE fitment dimensions so installation integrates with existing control arms and steering components. The set helps address common symptoms like play in the steering, knocking noises over bumps, and uneven front tire wear when those symptoms originate in the ball joints, tie rods or sway bar hardware.

How does this kit improve steering feel and road control?

Replacing worn ball joints and tie rod ends removes play at key steering pivots, translating steering input into crisper, more predictable wheel movement. Sway bar end links reduce unwanted body roll and help the front stabilizer work as designed.

• Restores tightness at lower ball joints for consistent wheel alignment.
• New inner and outer tie rod ends reduce steering lash and improve centering.
• Sway bar end links eliminate clunks and help reduce roll during cornering.
• Steering rack boots protect the rack from dirt and contaminants.

Which parts are included and how do they match my Corolla?

The kit contains ten pieces: two front lower ball joints, two inner tie rod ends, two outer tie rod ends, two sway bar end links and two steering rack boots. SCITOO designs these components to mirror OEM form and mounting points for a bolt-in fit on compatible Corolla model years.

• 2 x K90309 front lower ball joints sized for Corolla front suspension geometry.
• 2 x EV801193 inner tie rod ends to match rack spline and thread pitch.
• 2 x ES800525 outer tie rod ends for proper knuckle taper and secure fastening.
• 2 x K80230 sway bar end links and 2 steering rack boots included for complete front-end refresh.

When should I replace these suspension components?

Look for changes in steering behavior, new noises, or ride quality loss to determine replacement timing. Many symptoms are obvious during test drives and visual inspections.

• Steering noise or clunking while turning or over bumps suggests worn joints or links.
• Noticeable free play in the steering wheel or wandering on straight roads indicates tie rod or ball joint wear.
• If you feel every road imperfection more than usual, the front pivots or links may need replacement.
• Ripped or torn steering rack boots allow contamination and warrant immediate attention.

What should I expect during installation and maintenance?

Installation typically requires common suspension tools, a torque wrench, and alignment after parts are replaced. SCITOO supplies parts pregreased where appropriate to simplify installation, but a professional or experienced DIYer should perform the job and arrange a post-repair wheel alignment.

• Parts are pregreased to reduce prep work before fitting.
• Professional installation or experienced DIY recommended for safety-critical suspension jobs.
• Wheel alignment is required after replacing tie rod ends or ball joints.
• Inspect mounting hardware and related bushings when installing this kit to ensure full system reliability.
