Advance Adapters AOD KIT PROBLEM!

[Bhall75]

I ordered an AA AOD kit and new bushings from Bronco Graveyard and that is when the problem started. The original bolts (2) that were removed from my cross member were 9/16 outside diameter and the bushings are 9/16. I even bought a stock set of replacement bolts from Bronco Graveyard and they were 9/16. AA is telling me that from the factory, Early Broncos had a 1/2 bolts, not 9/16. My issue is the adaptor is tapped for 7/16 bolts and I have 9/16 bushings (from energy suspension) and 9/16 bolts. Has this happened to anyone else!?

Yes, it is in their directions. There should be a set of sleeves and bolts in their kit for that purpose.

The kit did come with sleeves and bolts but they are 7/16 sleeves and bolts, not 9/16 sleeves and bolts.

Yes, because the housing is threaded for 7/16" bolts. There is no way to use the stock bolts unless you want to drill and tap the housing the larger size. Is there a reason you can't use the 7/16" sleeves and bolts?

My main problem is that the bushings are made for the 9/16 bolts and not the 7/16 bolts. With the thickness of the sleeves, the 7/16 bolt and sleeve is not big enough. It will damage the bushing because it doesn't fit tight.

Does the sleeve supplied by AA fit inside of the sleeve that came with the new bushings or the original one?

 

[Bhall75]

It doesn't fit in the other. That was my first idea!

The bushings are a lot more tolerant than you are giving them credit for.

I ended up grinding the 7/16 sleeves on a wheel grinder and sliding them into the 9/16 sleeves. Did this by putting a bolt through them.
