Hi all,
I have a few questions regarding an axle swap, I haven't seen these specific questions on the forum by searching but forgive me if I am asking repeated questions.
I have an 86 Odyssey 4x4. Its has a six lug rear axle, however it is not a full floating axle so I want to replace it. I know that I need to keep several factors in mind when putting a new rear end in - wheel size, gear ratio etc.
My first question - Do I need to concentrate my search for an 86 rear end or will any other years offer the correct mounts for a bolt on application. I am trying to minimize the fabrication, but I do have the ability to fab and weld if needed. I have had more luck finding '87and '88 rear ends is the reason I ask this question.
My second question - Most of the rear ends I am finding have a gear ratio of 3.90. Will my third member with 4:10 gears bolt in without any mods needed?
My third question - Is the 6 bolt pattern on the full floating axle the same as the 6 bolt pattern on the 1-ton NON- floating axle? Curious if I am going to need to have a new adapter or wheels fabricated. I know that most dually wheels with full floaters are 14" and I am going to need to match the wheel size on my 4x4 which are 15"
All my wheels are 5 bolt pattern and I have 6 bolt to 5 bolt adapters all the way around.
Something else that has come up is aftermarket rear ends and conversion kits. Some people have said that the adapter kits aren't rugged enough to handle the weight. Does anyone have the exact specs on the factory Toyota full floaters as a comparison?
In the past when I have asked questions on boards, there were many responses shooting down what options I mentioned. However none of those people offered reasons why they shot them down or offered solutions to the problem.
Any and all information would be greatly appreciated.
Thanks
Sean
