2019 Fiesta ST. I dropped the subframe to install a new turbo and as I put it all back together, the driver side rear bolt goes in only about 3/4 of the way then gets super tight. I don't want to risk breaking it so I turned it out and tried a couple more times, same result. It threads in by hand easily for the first half or so, then gets tight and only goes another couple turns with a wrench before it gets tight. Still about 1/4" sticking out. I thought I might have cross threaded it, but it screws in by hand so easily for the first half, I feel something else is wrong. when I examine the threads on the bolt they are all good, except the first thread, looks like its starting to round a little. The two front bolts and the passenger side rear went in easy as pie, kind of stumped. The bolt I'm talking about is W714343-S900 , I was thinking of trying to run a tap through the hole to see if I can straiten anything out thats threaded wrong, but I can't find the bolt size to get a tap thats right. the hardware store says its a 14x2, but alot of Ford parts for that bolt are saying 14x1.5 on other Ford vehicles. Any ideas or help would be appreciated.
