Ford f100 gets a modern rear end: Disk brakes and 4 link suspension

I love working on this truck. Probably more than the Falcon. In this vodeo, i get the rear end swapped out after i discover that the 9 inch in the truck is trashed. Thankfully I had a good 8.8 waiting and ready to go. Watch as I struggle to get the measurements correct while installing this new rear end with a parallel 4 link.

Good stuff Rob, I really like how you don't hide your struggles, Cobber... you share all the dramas & even the f#ck ups that challenge you & how you overcome them. Wish I had an old F truck to play with, don't paint it. I hope the well body is as nice & patina'd as the cab. What a good dad you got. And the music today... much more appropriate..I've been toying with the idea of a 8.8" for my XP Aussie '65 Falcon wagon. Apparently the pre 2000 Explorer's had 31 spline axles & LSD & they're pretty cheap. Only thing is you need to remake the tube on one side or buy 2 diffs because the stagger is so large, one side t t'other. Really enjoyed this video.. I'm catching up to almost present day.

Yeah I can get away with the offset in the truck. Bigger deal in a falcon for sure.

Kevin Wilson's channel has really cool stuff on chassis 4 link set ups Rob.

I’ll have to check him out!

Cool I can do the same thing on my f100 with some 24 inch shackles and my cut of wheel I’am on it! All kidding aside good video.

[@rdspeedfab]

Yeah man. Nothing stopping you! 🤣

[@rickyfulks889]

Hey, if it aint broke dont fix it😅

[@williamguillIII]

Off topic, but, what size wheels do you have on your Falcon?

[@rdspeedfab]

No problem! They’re 17x7s. I have a full video on measuring the car for backspace and getting the right fit. It’s an older video but still has some useful info in it.

@@rdspeedfabThanks. I have a 65 Falcon with an 8 incher and thought I'd ask.

[@rickyfulks889]

Is ur pinion angle up?

[@rdspeedfab]

Yeah three degrees roughly. You want it opposite and equal the transmission. 3 degrees down on the tail shaft is pretty typical. I’ve always set them up like this and it works great.

[@rickyfulks889]

@@rdspeedfab but under acceleration ur rear end twists upward, so u need pinion angle 3 degrees downward. Opposite of the twisting motion of rear end.

[@rickyfulks889]

@@rdspeedfab I follow u on equal n opposite angles, accounting for the twist also. I suppose if ya dont plan on hard hits its fine

[@rdspeedfab]

@@rickyfulks889 yeah I definitely wouldn’t do it on a leaf spring setup. It would be closer to zero because the spring would wrap and the pinion would change up to around three degrees. 4 links don’t really change pinion angle on a launch. I mean they’ll deflect a little but not anywhere near what a leaf spring setup would do. Maybe half a degree.
