My Bronco has a 8.8 with 31 spline yoke, and was stock. Get a Spicer 31 spline yoke. Jeff’s Bronco Grave Yard sells them, but shipping is very slow.OK, so I've had the truck in the shop since after the new year and this is what I know so far...
- The noise / vibration issue around 60mph that we as a community believed to be the passenger side hub lockout has been replaced (as has the drivers, since they are sold in pairs) and that issue is resolved.
- There is another noise / vibration coming from the rear of the truck when you get into the mid-60s which I didn't know about because I always backed off from the first issue. The shop claimed it was the driveshaft, so they pulled it off and took it to a specialist company that did some magic and handed it back. Now they are saying some of the issue is resolved, but they noticed when installing it that the yoke / splines are not correct and that's causing slippage / power loss and likely the root of the drive shaft issues. I believe that from Ford, this would have been a 29-spline unit, but apparently, they are seeing 31? At this point, they aren't sure what is going on, and suspect that maybe the rear end isn't from Ford. Apparently, they can't identify it and are considering just putting the truck back together and making it my problem??? I have no idea, but I did some digging and found that Yukon sells Ford yokes with 31 splines for this year / setup. I passed that information over to the shop and I guess will see where that goes. They are closed on weekends, so I'll try to follow up next week.
