Dana 30 King Pin Rebuild

[Bonefizz]

Bronco Gurus,

I'm rebuilding my Dana 30 King Pins and dampeners and I'm struggling with them. These don't make sense. I must be doing something wrong.

I've followed the diagram on the Wild Horses website, but things don't seem to be lining up. First question, is the bearing run supposed to be pressed on against the cup, or above it. Second, if I install the dampener and washer, then the bearing isn't making contact with the run. It sits above the run. Third, is the dust cap supposed to sit flush when it's installed? It seems to sit up too high. Also, should the bearing move around under the dust cap?

I've got them together, but don't have any confidence that they are correct. I'll upgrade to a 44 at some point, but this will have to work for now.

Thank you,
Clint

I thought this was the hardest part of my build. The WH diagram was the most helpful thing I could find. Do you have a 66? I think the 66 is a bit different and doesn’t utilize the damper. I think I may have some pics in my build thread probably summer 2018 timeframe.

I have a 69. Thank you for those pictures, it looks like I’m on the right track.

In your picture #3, does not look like the bearing race has been set down in place. You need to use a race set / seal set or drift to make sure it is set all the way down in the housing. Once done, when you place your bearing and seal in, they will sit lower. Look at chuckyb's 4th picture.

Perfect, thank you. I’ve got them all pushed down to the cup except one, it’s being stubborn. Of course, it’s the upside down one. I may need to pull out the torch and stand on my head to get it.

The upside down hammering is a PIA. Keep going at it as evenly as possible and it will go in.

I ended up putting the run in the freezer for a couple of hours and then it slid right in. Should have done that for the other three!

I finished installing my steering knuckles and shims late last night. What a pain!

Thank you everyone for your input, you were all a big help. I love this forum!
