mat in tn Posted January 5, 2023 Share Posted January 5, 2023 Ok, confusion came from (on my part) screen name brianbronc and the original post title "1986 F240 I6", I figured Bronco six cyl, not an F250 with twin traction beams. Since the front drive axle on these has leaf springs that both bend and twist under load and that are, other than the inboard pivots, what keeps the axle in alignment, a bent spring on either side would mess up the alignment. I would take a real good look at the right axle pivot bracket (left side of cross member) and make sure it isn't damaged. As for kids breaking stuff, my oldest son (now 55) destroyed a rear axle in my 1961 Mercedes-Benz 220Sb hopping speed bumps at the local community college when he was 17. I told him he was lucky I had a spare axle for it. Long story short, he decided the car could just sit as neighbor's son could take him to and from school. Concert or something they wanted to go to arose, neighbor says you're not taking my truck. Saturday morning of the concert, at 7:00 AM there are 4 teenage boys out on the driveway with the M-B service manual in hand. They got it done with time to spare. there are a couple things I noticed. was the bumper bent up on the passenger side before? I don't see a twist in it, but it is up. I'm concerned that the frame may have taken a hit also. If the tire/wheel hit the culvert at the bottom, then the leverage would have been to bend it to the other direction giving positive camber and not necessarily transfer to the other axle as they are independent. so how it was able to create negative camber on both sides is bit of a mystery.

grumpin Posted January 5, 2023 Share Posted January 5, 2023 The pic of the truck in the ditch... well the front passenger took a good whack up against the bank at the culvert. Blew the tire. Front leaf spring - twin beam axle Front leaf... you can see the front passenger is no longer having the curvature in it. If you backed the truck up, off a trailer or whatever, push it or drive it forward. See if the negative camber goes away. Link to comment Share on other sites More sharing options...

mat in tn Posted January 6, 2023 Share Posted January 6, 2023 the front bumper was not bent before it went into the ditch... look for evidence of the bolts being "scooted' or the bumper being bent itself. if neither are evident then it may have twisted the frame a little Link to comment Share on other sites More sharing options...
