On the door for stock tires, it says 60 P. S I front and rear. Doesn't show any difference for load. What is everybody running with 35 A/Ts and maybe a 12000 pound 5er?
No, definitely coming from the CP3, I can hear something internal with a stethoscope, very noticeable between idle and 1200 RPM. First noticed it driving in my neighborhood with the windows down. Have a friend who also has a 2020 with the CP4 to CP3 recall. His also make the same noise but mine...
I bought this 2020 in February whistling noise coming from front timing cover or fuel pump C P4 2CP3 recall done before I bought. It anybody know if this is normal?
