Steering problem, please help

[WhiteTE72GT]

Alright, my problem is that when I turn the wheel slowly and constantly, it will follow then it will suddenly bite and turn harder. It started happening after the car was already aligned. I just replaced the rack and pinion thinking it was it but after replacing it, its still doing the same thing. my mechanic inspected the steering assembly and everything was still tight and shouldn't be causing the bite. I wanted to know if anyone else had this problem. Any help will be appreciated. Thanks

oh and after it bites the steering wheel itself will turn more but you can bring it back to what it was when you turn it back. I tried to search here in zilvia and didn't find anything and also google. I'm having connection problems with nico so i couldn't fully search in there.

does it turn hard when you hit a bump? did you get an alignment after you installed your rack and pinion? if that's the case, you may need another alignment.

Not really. The car was already aligned when it started happening before I replaced the rack.
