I thought this might be the best place for this but if not let me know.
In the back of my mind I have been planning on building a full float rear axle for my 2001 tacoma. This would be the first time I have tried to build an axle like this, so I am hoping to get some advice from those that have done aiming similar. I have read plenty of similar threads so far but this is a little different.
I have an early 1963 centered fj40 semi float housing that can take a 9.5" differential. I have a set of full float ends from an 80 series axle that I plan to attach in place of the current semi float ends. Then use all 80 series end and ebrake to complete it. I have a full float 80 series diff that I would use with an Eaton blocker or possibly source a toyota locker diff. In hopes it would plug into my existing factory harness.
The tacoma wms is just under 61".
The fj40 wms for the axle I have is 55".
The 80 rotors and hub assembly will add some width and the remaining if needed will use the 80 housing tube extending from the hub.
I read that the differential to housing studs are smaller on the early axle housings. I would plan to drill and tap them to take 80 series studs.
I expect I might have to modify the housing to accept the 80 diff but not sure. Definitely would if I went with a factory 80 e locker.
I am thinking it is an older housing and I have not compared it structurally to new housings for thickness. So I am thinking I would add a truss.
I would plan to mock it up the way I want and tac it together then get a shop to finish welding it. Plan B would be to build and buy jigs to weld it myself - Not ideal.
This is as far as I have gotten in my head. What do think?
