The helical-cut pinion and linear rack gear set is manufactured to DIN or JIS Q7-Q9 accuracy class. The controlled tooth profile geometry supports consistent steering ratio, minimal backlash, and smooth input transition across the full lock-to-lock range, reducing the risk of vague steering feel or off-center wheel position after installation.
For HPS configurations, an engine-driven pump delivers 80-120 bar of pressurized hydraulic fluid to a double-acting cylinder piston on the rack bar. This hydraulic force amplifies driver input by 15-20 times, enabling reduced steering effort during low-speed parking maneuvers.
A multi-layer sealing system protects internal components: a rotary shaft seal at the pinion input blocks dirt ingress and fluid egress, rack bar bushing seals maintain internal lubrication, cylinder end seals contain operating hydraulic pressure, and thread protection caps prevent shipping damage. Individual seal degradation can cause gradual performance loss, from minor seepage to full assist failure.
Installation of this steering gear addresses common steering system issues: excessive free play from worn gear teeth or loose bushings, heavy steering from internal seal failure, off-center wheel position from bent rack bars, fluid leakage, and binding from damaged bearings. Professional wheel alignment is mandatory after replacement, and power steering fluid flushing is recommended for HPS systems.
This assembly corresponds to OEM 56500-1G000 and fits the following compact SUV models:
Hyundai Tucson (LM/JM): model years 2010-2020
Hyundai ix35 (LM): model years 2010-2020
Kia Sportage (SL/R): model years 2010-2020
Business buyers can verify fitment by cross-referencing the OEM part number with a vehicle VIN through authorized dealer systems.
Common root causes include worn inner tie rod seals, heat-damaged pinion shaft seals, porous rack housings, and deteriorated hydraulic line connections. Diagnosis can be made by observing fluid drips from rack boots, dropping reservoir levels, pump groaning noises, or visible wet staining on the rack housing. Minor outer seal leaks can be addressed by replacing the affected seal and boot; internal seal failures require full rack replacement. System flushing, fluid refill, and bleeding are required after service, and outer tie rod ends should be replaced alongside the rack.
This issue typically stems from spool valve wear, contaminated fluid restricting flow, or a damaged power steering pump. Symptoms include increased effort during parking, uneven left/right steering feel, and loud pump whine under load. A full system flush is recommended as a first step; if issues persist, the steering rack and pump should be inspected and replaced as needed.
Yes, this assembly fits Hyundai Tucson LM/JM models produced from 2010 to 2020, corresponding to OEM part number 56500-1G000. It also fits Hyundai ix35 LM and Kia Sportage SL/R models from the same year range.
This product is assembled to Mobis/Hyundai-Kia original production specifications and complies with IATF16949 certification for safety-critical automotive steering components. Each unit undergoes 100% rack tooth lead error inspection and hydraulic pressure decay testing prior to shipment.
This product supports minimum order quantities of 500-1000 units for bulk commercial orders, suited for auto parts distributors and large workshop chains.
Yes, three packaging options are available for bulk orders: genuine Mobis standard packaging, neutral aftermarket packaging, and branded aftermarket packaging. Neutral packaging is the most widely selected option for commercial distribution.
