I have a couple questions.
The 2 codes set, cleared them and they reappeared.
P0455- gas cap is new, visually looked at all lines and such.I know it probably needs smoke checked/function tested. Just want to know most common thing that fails. Like on all my GMs its been the evap vent valve.
The P0505, it does idle rough at times. Like steering wheel will shake and after a little while it idles fine. Is this the IAC?Would cleaning it help?
Next. My radio wont take the code I got from Volvo. Got it off the serial and part numbers on the radio tag. Tried it 3 times, went to off, left key on for 2 hours, code reappeared, tried it again and wont take it. Whats the next move?
Next.I have to replace my broken spring seats and passenger side axle. Gonna remove struts and have local shop swap out parts. My question is, any thing I need to know special, any tips or tricks on changing axle or struts?
Do I really need to apply metal adhesive to axle splines?

Thanks in advance to any and all who offer assistance

You will need to smoke test the evap system to see where the leak is at. PO505 inspect the hose that connects to the idle air valve for leaks. You can try and clean it along with the throttle if no fault with the hoses is found but you will most likely need a new valve. The radio code, did they give you the code by reading off the serial number off the radio? Go back to Volvo and have them do a vehicle inquiry and see if that code they have on hand matches what they give you using the serial number on your radio? If neither one works then they will need to call the hotline for further advise. As for your last question, should be the same as any other vehicle but do not use the metal adhesive. Use some anti seize instead. That should minimize the pingin sound during garage shifts. If you use the adhesive, good luck removing that axle again in the future? If you do happen to get it off you will need to clean every single spline in the hub and axle to be able to reinstall it? Good luck to you.
