Electric Power Steering (EPS) System for Ford Mustang

[Mustangf150]

The slanted-tooth belt within an electric power steering (EPS) system is vital to performance for Ford Mustang. Because the oblique belt helps determine power consumption and driver use. All EPS belts need to do during driving is to transfer torque from the motor to the steering gear.


To supply steering power by an electric motor mounted to one side of the rack driving a ball-screw mechanism through a toothed rubber belt in EPS system configurations with paraxial servo units.


EPS belts are made with a good grade HNBR polymer to prevent environmental contamination and resist oil. So the belt is able to operate under extreme temperature fluctuations without problem.


Advanced engineering gives electric power steering belts unique characteristics. High load capacity, resistance to tooth jump, reduced span vibration, extreme temperature variations, high resistance in the tough working condition, long-lasting performance.

You seem to know a bit about the steering system in our mustangs. What does tooth jump feel like? I'm having issues with my steering feeling notchy. like there's a small resistance I'm having to overcome every time I change steering direction.

What is the purpose of the OP posting; does he/she have an issue with the EPAS system, or just posting the above as an FYI?

I had listed the proper belt size and where to buy it a while back if anyone needs to replace their EPAS belt; it is an internal serviceable item, see my post #7 of this thread:

The important question for me is this: Can we tighten the steering ratio more so it's more responsive to inputs?

The only way to do that would be to tap into the EPAS “As Built” using Forscan or an equivalent to Ford’s IDS... Each S550 platform has different EPAS values, which is what the driver feels in feedback and how the steering performs.

I had some input into similar EPAS threads on this a while back, but can’t find them at the moment (prob not hitting correct search terms).

EDIT:
Here’s one of them:

Every figure this out?

I'm taking the car in Monday to get looked at and see what's going on. The problem has slowed down and not been doing as much as it was but it's also been only city driving and. Will keep you guys updated.

see my post #7 of this thread:

Can you give a part number, when I look at the linked thread it turns into a click bait type thing.
