Did a wheel bearing replacement. Back of brake rotor now touching lower control arm lip. Everything is torqued to spec. Only about .03” gap on unchanged side. Any advice to fix before I have to buy a whole new steering hub for the passenger side? Thank you all. ---

Let’s see? We know it’s a Hyundai. Tester ---

Well I have the rotor off now but it’s just ever so slightly touching. There’s a faint scratch on the rotor. Could it be the alignment? I did completely remove the knuckle to replace bearing and spindle. It’s a 2019 Hyundai accent sorry just realized I never included that. ---

Are all of the affected parts (rotors, control arms) original to the car as built, new? ---

The wrong wheel bearing may have been installed or the bearing was not fully pressed into the steering knuckle. Did you install the snap ring? ---

Wait? How is the rotor capable of touching the control arm with the rotor splash shield in place? ![db135934ee4fec819dc70a26657da333](https://global.discourse-cdn.com/cartalk/original/3X/1/b/1bff133b9c42782358ee34e1408b3784f7e1c916.png) Tester ---

Yes. Driver side has original parts. Car only has 50k miles after owning for almost 5 years. I’m thinking 1 of 2 things happened. Either alignment is borked from being on jackstands for almost 2 weeks, or spindle was pressed too far into bearing after bearing was pressed into hub. Unless anyone has other ideas I’m going to look into the alignment, if that fails I’ll pull the spindle again, pull the bearing again, probably have to order another new bearing since I’m expecting this one to blow apart even tho I used grease on install, and then reassemble with a different setup of press plates so I can stop the spindle end flush with the bearing face. ---

Ok so issue is this then. Different steering knuckle since Hyundai also owned by Kia. Accent = Kia Rio of same year, had to order Kia bearing when Hyundai didn’t fit. BUT I did verify that the accent and the rio use IDENTICAL spindles. Only notable difference is OD of bearing. But I’m leaning to thinking the spindle was pressed too far in. ---

Your original post threw me off. I thought you typed _back brake rotor now touching_ when in fact you typed _back of brake rotor now touching._ Control arm ball joint may be worn. Tester ---

Ball joint is still good boot not ripped and yes replaced snap ring behind bearing. ---

Then, if everything was installed correctly, it’s gotta be the replacement bearing assembly. Tester ---

I for one want to see a picture of a rotor touching a control arm. Maybe the rotor is touching the strut because you turned the strut 180 degrees when you put it back together. Edit: could you have put the backing plate on backwards, it will touch the rotor, make a lot of noise and that is very easy to do. I’ve done that few times. ---

I’ll try to upload one later this week. Same rotor so backing should be the same also. ---

The way that ball joint stud is leaning in, clearly there is a problem somewhere. ---
