Steering parts are put through their paces

Delphi has added an additional 175 new parts to its steering programme this year, with more than 450 planned throughout the remainder of 2017. Components such as wishbones, inner/outer tie-rods, link stabilisers, rubber-to-metal, ball joints and rod assemblies fitted to popular UK applications join the range for applications including the Citroen C4 Picasso II (2013>), Ford Transit (2012>), Hyundai i40 (2011>) and Range Rover Sport (2013>).
Delphi engineers carry out a range of tests to check for resistance to corrosion and cracking and to ensure geometric compatibility between the OE and aftermarket product. Additional testing is unique to the individual part and designed to replicate the same stresses the part will be exposed to in the real-world. Take the link stabiliser – push/pull fatigue tests simulate road conditions, testing the part thousands and thousands of cycles until failure occurs.
The same goes for wishbones. Delphi tests all three axes to replicate side-to-side movement, forward force from acceleration and deceleration and up-down movement. The wishbones must perform in a safe and consistent manner by managing all three forces at the same time, for at least as long as the OE part.
