All ball joints come pre-greased from the factory — no messy grease gun work required. Replacing all wear components at once ensures balanced handling and prevents the "domino effect" where a new part stresses old, worn components. Backed by iFJF's warranty against manufacturing defects.

Frequently Asked Questions
Q: How do I check if I have 10mm or 12mm sway bar link studs?
A: Measure one sway bar link stud with digital calipers. 10mm diameter = this kit fits. 12mm diameter = you need a different kit for Sport/4Matic models.
Q: Will this fit a 4Matic (AWD) Mercedes?
A: No. This kit is designed exclusively for RWD (rear-wheel drive), non-Sport suspension C-Class (W203) and CLK-Class (W209) models. 4Matic and Sport models use 12mm sway bar link studs.
Q: Are the ball joints serviceable or sealed?
A: The ball joints are sealed and pre-greased from the factory. They are not serviceable — when wear develops, replace the complete control arm.
Q: Do I need a professional alignment after installation?
A: Yes, a professional 4-wheel alignment is absolutely necessary after any suspension component replacement. Skipping alignment will cause rapid, uneven tire wear.
Q: How long does installation take?
A: A professional shop can complete this in 3-4 hours. DIY with basic mechanical skills and tools should budget 5-7 hours. A ball joint press and spring compressor may be needed.
Q: Is this genuine Mercedes or aftermarket?
A: High-quality aftermarket manufactured to meet or exceed OEM specifications. All components are IATF 16949 certified — the same quality standard required by major automakers.
Q: What symptoms indicate I need this kit?
A: Clunking or knocking over bumps, wandering steering on the highway, uneven tire wear, loose or vague steering feel, and visible cracking of rubber ball joint boots all signal worn control arms and tie rods.
Q: Does this kit include the alignment bolts?
A: Standard mounting bolts and nuts are included. If your vehicle has seized or rusted alignment/camber bolts, order those separately from your local dealer.
