I've spent almost an hour searching through posts and was unable to find the information.

Can someone tell me what size/thread the 4 bolts that hold the wheel bearing hub in the solid AAM axles?

I'm going to attempt to replace the ball joints and would like to have some spare bolts just in case I screw (no pun intended) these up during removal via the power steering method.

 

I can not remember the size off the top of my head I just did this last weekend. I have to re-torque every thing tommorrow so I will let you know. I did not damage the bolts at all when I did the power steering method. I had a random assortment of 3/4 blk nipples for gas fitting, that fit over the head of the bolt perfect and rested on the shoulder of the bolt instead.

 

anyone else?

 

the bolts are 9/16-18x1.25''. what it says in the instructions from my dynatrac kit

 

Thanks

Hopefully I won't need them, but I figure it can't hurt to have a few extra bolts on hand.

 

I went through this with Dynatrac a couple of weeks ago when I installed my Dynaloc kit. THE SPECS THEY LIST FOR THE HUB BOLTS IN THE DIRECTIONS ARE WRONG!!!!! I even went so far as to call Dynatrac to advise them and they told me they would change the directions. I too wanted the extra bolts just in case. I spent a couple of hours at a Fastenall store (all they sell are bolts) and they could not find one to match after trying the 9/16 bolt that was listed. I ended up ordering it through Dodge. Yes more expensive. Part # for the bolt is 5086661AA. I had to pay $23.28 for the eight bolts. After getting them I was able to tell they were 14mm with a 1.5 thread pitch which is hard to find.

The Dynaloc kit installed fine. In fact it was part of a major retrofit of the front end on my truck. I installed
1) Front Detroit True Trac differential
2) Dynaloc Kit
3) The Dodge Upgrade Steering Kit
4) Thuren Trac Bar
5) Thuren Fox Steering Stabilizer
6) HD Control Arms with poly bushings, made with .25 wall steel tube
7) Hummer Wheels (the new 2008 style)
8) Toyo 285x70-17 M/T-Open Country

 

Glad someone posted this. Two of the bolts have abandoned ship and two are loose. Hopefully the size posted here will work. Confirmed w/a bolt thread pitch gauge....14mm w/1.5 thread pitch. Unable to find locally....guess I'll order online.
