How to replace the Rack and Pinion Boot on Kia Optima?

Free up the lug nuts, lift the car and put it on jack stands then remove the wheel. Next, unbolt the tie-rod end and the jam nut that is screwed on to it, if fitted. Next, loosen the rack and pinion boot clamps and pull off the boot by unbolting the outer clamp as the inner clamp may be clipped, cut, or pry off. Before fitting the new boot, it will be pertinent to cover the threads and serration features at the edge of the steering rod with a layer of tape to avoid damaging that small end of a new boot. Place new boot over the rack and pinion and slid it into its position up to the groove on the steering rod and then fix new clamps. Once the tape is removed, the tie-rod end has to be installed next. Last, fix the wheel and the lug nuts, and lift the car before finally tightening lug nuts to the correct torque, though it's advised to get the alignment test from dealer service department or any alignment shop.

Kia Optima Rack and Pinion Boot

Kia Optima Rack and Pinion Boot is a flexible rubber shield that keeps dirt, water, and road grit away from the steering rack gears, guarding smooth and accurate wheel response. Mounted at both ends of the rack tube on Kia models, this seals the tie-rod openings to lock in grease and block debris that can shred the internal seals or drain hydraulic fluid. The Rack and Pinion Boot allows the inner tie-rod to pivot freely and retain lubricant to prevent metal-to-metal wear and early joint failure. Early Optima versions equipped with manual steering applied the same basic Rack and Pinion Boot, but for later power assist applications, the rubber had to be built more sturdy to handle the increased fluid pressure and heat. If the boot is torn, the grime will rush in, the fluid will leak out, and the rack will be able to grind, wander, or stiffen so Kia drivers should check it for any tears or sticky residue on their Optima during routine checks. Quickly replacing a worn-out Rack and Pinion Boot stops fluid loss and returns to a light, centered feel. A new Rack and Pinion Boot costs far less than a complete rack assembly, making it a smart protection for every Kia Optima owner.
