How HaoYu Rack Ends Are Manufactured?
Each rack end is produced in a controlled process to achieve stable quality and repeatable performance.
- Raw Material Selection
We use high-strength alloy steel or carbon steel bars specially selected for steering components. Incoming material is checked for composition, hardness and surface defects before storage. - Forging or Bar-Cutting
Depending on the design, the inner tie rod body is either hot-forged for extra strength or precisely cut from steel bar using automatic saws. This guarantees consistent blank dimensions. - CNC Machining
All critical surfaces – threads, ball seats and spanner flats – are machined on CNC lathes and machining centers. This ensures accurate fitment on the steering rack and rack end nut. - Thread Rolling & Drilling
Internal and external threads are formed with high-precision tools. Thread gauges are used during production to make installation smooth for your customers. - Heat Treatment
Key areas are heat-treated to reach the required hardness profile. This improves fatigue strength and resists deformation under steering load. - Surface Protection
The finished bodies receive phosphating, dacromet, electrophoretic painting or zinc plating to protect against corrosion in humid and coastal markets. - Assembly & Greasing
Ball studs, springs, seats and housings are assembled on dedicated fixtures. High-performance grease is filled to reduce friction and noise during operation. - Final Inspection & Packing
Each batch is checked for dimensions, torque, thread quality and appearance before being packed into neutral or HaoYu-branded boxes, then strong export cartons.
How We Inspect HaoYu Rack Ends’ Quality?
Stable steering parts need strict quality control. HaoYu follows a clear inspection plan from incoming material to final shipment.
Incoming & Process Control
Chemical composition and hardness test of steel bars
Dimensional inspection of forged or cut blanks
First-article inspection on CNC programs for every new batch
Assembly & Functional Tests
Torque test for ball stud articulation to secure smooth yet tight movement
Axial and radial play test to avoid looseness and steering vibration
Thread gauge inspection on inner and outer threads to ensure easy installation
Dust boot sealing test to prevent water and dust from entering the socket
Salt spray / coating thickness test on surface treatment for corrosion resistance
Final Audit Before Shipment
Random samples are checked again for appearance, marking, packaging and labelling. Only qualified rack ends are allowed to be loaded into containers.

Where Are Rack Ends Located in the Steering System?
The rack end, or inner tie rod end, connects the steering rack to the outer tie rod end. It transfers steering force from the rack gear to the wheels and sets the vehicle’s toe angle.
Basic Rack-and-Pinion Layout
In a typical rack-and-pinion steering system, the steering wheel turns a pinion gear which moves the rack left or right. The rack ends are screwed into each side of the rack and connect to the outer tie rods.
MacPherson Strut Front Suspension
Most modern passenger cars with MacPherson struts use rack-and-pinion steering. The rack ends work together with the outer tie rods and lower control arms to control the wheel angle and tire wear.
Double-Wishbone and Multi-Link Front Suspension
On double-wishbone or multi-link front suspensions, the function of the rack end is the same: it links the steering rack to the uprights through the outer tie rods so the driver can precisely control toe-in and toe-out.
Importance of Quality Rack Ends
Worn or poor-quality rack ends may cause steering play, tyre feathering, noise and safety issues. That’s why many distributors prefer consistent quality from a focused steering and suspension supplier like HaoYu.

Q3: Can you develop new rack ends from my samples?
A3: Yes. Please send us 1–2 pieces of samples or detailed drawings. Our engineers will measure thread, length, taper, and ball size, then create a drawing and sample for your approval before mass production.
Q4: What kind of grease and boots do you use?
A4: We use high-performance grease suitable for both hot and cold climates, combined with high-quality rubber or thermoplastic boots to keep dust and water away from the ball seat.
Q5: Do you offer economy and premium lines?
A5: Yes. For some popular applications we can offer two levels: an economy line for price-sensitive customers and a premium line with higher-grade material, coating and warranty. You can decide which line to stock in each market.
