    Upper O2 Sensor Failure

    That is what I thought. It's interesting how frequently that position is turning over in dealerships. At least the ones here.

    Upper O2 Sensor Failure

    Our 21 explorer ST has a upper 02 sensor that has failed. The service manager told my wife that this will continue to happen unless we use premium fuel. We currently fuel exclusively with ethanol free gas running 88 octane. Is what he saying true at all? I don't think so based on the fuel...

    Catalytic Converter Cracking

    When I talk to the dealer, they say that the problem has NOT been resolved in the factory parts. So they won't replace it, but I see other folks that are having parts replaced. That's what I am trying to figure out. Does my dealer know what they are talking about or not?

    Catalytic Converter Cracking

    Our ST has been parked at the dealer for 2 weeks due to exhaust smells in the car because of a cracked catalytic converter. They say the factory replacement cats are cracking as well. So the car continues to sit there. I am checking on the dealer with this post because I’m concerned it’s...

    Question About Snow Tire Fitment on ST

    Your probably right. To be honest I didn't play with the snap gauges for very long to make sure I was in the widest part of the bore. I was just looking for the 70.5+ number. Can someone explain where you need to use a HCR and when you do not? I know they are optional, but never really...

    Question About Snow Tire Fitment on ST

    I might be lucky for once. I measured the center bore with snap gauges and calipers and the bore is 72 mm. I also calculated the offset of the wheel to be 35 mm. The factory 21" wheel offset is 37.5 mm. So, adequate bore and a few mm only in offset difference. I think I am good to go as...

    Question About Snow Tire Fitment on ST

    It sure did on my F150 and Wrangler when I was playing around with tires. That's why I asked.

    Question About Snow Tire Fitment on ST

    Agreed. Thanks for the help! So dumb question - the diameter change doesn't matter because the explorer pulls the speedo off the transmission?

    Question About Snow Tire Fitment on ST

    I have a set of 20" snow tires on rims that used to be on my 2018 Ford Explorer Limited that I would like to install on my 2021 Ford Explorer ST. I still need to verify the offset, but my question is more related to the outside wheel diameter. The 275/45R21 tires have an outside diameter of...
