Most of the electronic power steering racks have a motor attached with an internal toothed belt like a timing belt. When the belts break or jump a tooth they do what your describing. Last I checked they're not serviceable and pre-calibrated by the manufacturer so that you have to buy a new one when the old one goes out. I'm sure someone somewhere has figured out how to do this but parts for them are impossible to get.

crappy idea + poor design + poor parts = one big fiasco. One more reason I'm keeping my 2007.

I wish you luck in finding a new one

Thanks for the info on the timing. That does make sense. I know I have found belts for this part online and seal kits. But nothing else. But it might take some digging to find how to time this thing but thank you so much for the info.

 

It MIGHT be self learning. I worked on these on fords and there was no calibration options, had to send to supplier. I have not done one on a Ram so it might be as easy as install a new belt and do a calibration procedure. the thread Tom-G posted will be worth a look.

 

On the Rams, when an EPS unit is replaced the truck’s computer (I don’t know which one) has to be configured/sync’ed to the computer in the new EPS unit. I’m not aware of any further calibration. This information is from various sources I have read in the past but I have not done this myself. Just passing on what I recall from my readings.

 

The few I have done are similar. The calibration is programed into the onboard module at the manufacturer. On the ford ones at least. If it skips a tooth on the belt all sorts of issues arise and even the dealership I worked at couldn't repair them, only replace. That was back in 2015 though...maybe its gotten better.

Either way It was enough that I simply don't want to ever mess with owning one. I'll keep my old stuffs.
