Please Help about reel penn 110 Senator 1/0

[theblackrose]

Hello everyone!! My name is Leon, I'am new here. I have a problem with my penn senator 1/0, the spool is wobbly to the front & behind (not to the left or right side which can be adjust with the side plate cap) happened at the handle side when retrieve & cast, but the spool stub axle is just fine (I roll it at the glass table & I can't find any problem with the spool), also I just replace the right side bearing (I thought the problem was the R.S bearing) but still not solve the problem. If any body here have an idea or have a thought with my reel please let me know
I will be very appreciate with any of your information.
Have a nice day & thanx for your time.
