What I see isn't the standard U style bolt style caps. The cap to the flange is a flat foot with an index web and the mount is fastened with bolts coming through the flange from the Diff side and threads into the U-Joint cap. Ford used that style caps from 1955 up to mid-year 57. At least in the photo I see.
Sorry didnt mean to insult you but I am a welder. I suggest pull the drive shaft out take it to a drive line shop only need hand tool to remove it have it checked.
If there's no vibration on a test drive why spend the time and money? It's not like they would do a test to check for penetration.
I wasn’t insulted. Thought it was kinda funny honestly… just didn’t help my original intent… but there seems to be a lot of rabbit trails on this thread anyhow.
Enlarge and take note please. Notice the flange or yoke as some call them on the rear Diff. It does not use the standard U style bolts to hold the rear joint in place. Carry on.
10 psi at warm idle for a 351 windsor is not a death sentence, had one in a rod for 15 years like that.
On my old 460 powered Lincoln I drove that car 150,000ish miles in 4 years with the oil pressure dropping to near zero once it was warmed up and idling... Back then I did not know that it was coppered bearings that caused the oil issue (I was a kid and didn't have the years of driving junk yet for experience points). Anyways I used to run 60-weight vr1 Valvoline racing oil and bardell no smoke to give the car a little bit of oil pressure I'm not kidding you I drove that car forever that way it would burn 2 quarts of oil on the freeway going from Southern California to Las Vegas I ***ume it was just going right by the rings... Ironically that engine never gave me a problem and I drove that car like I stole it 3/4 of the time I was in it, I have to say I kind of miss my early twenties lol. If I would have had 10 psi of oil pressure that would have been like a brand new engine and I would still be driving it. What what actually caused me to quit driving the car was the transmission lost second gear and it made it miserable to drive with any bit of an incline. Now that being said I would definitely put bearings in it before it gets worse and make sure to stay up on your oil changes if you caught it soon enough you won't have to do anything except put new bearings in it.
I’m thinking about doing an in the truck bearing change soon. I haven’t done much to the truck as of late. Did focus on the steering box a little bit. Once it’s finally happy, I’ll be dropping the pan for bearing change fun. I may run a borescope in the cylinders first, or run my luck and just change them. Live life dangerously, lol.
