Assuming you are talking about mini trucks.....I dont believe there is a difference in the body.
But, the IFS is 27 spline and the solid axle is 30 spline. so all you need to do os swap out the gear. (longfield sells chromoly ones for 60$ IIRC)

IFS and solid axle hub bodies are different. Most of the difference is the dishing at the base. The handle and clutch assemblies are the same from solid axle through Tacoma and interchangeable. The 30 spline gear from the solid axle hub will fit into an IFS hub body, but I haven't tried to see if the Birfield will line up correctly.
Ummm, weekend experiment? I have both in the garage.

Yes it works I know of many people who just swap the 30 spline gear in and it works EXACTLY the same as the solid axle hub.
Which begs the question "why would you want to?" If you have the gear, you also have the body. Why not just run solid axle hub? The last I checked the gear was not available from Toyota as a separate part, but is available from Longfields.

On the way there
Because the IFS hubs are easy to get and cheap.
Longfield sells the replacement gear made out of chrome-moly steel. So in effect, you can convert an IFS hub to a solid axle hub that fits Minitrucks, FJ40, FJ60, FJ62.

Aren't the IFS hubs a little shorter? IE they don't stick out so far? That's stuck in my head for some reason...
Yup'ers
I really dont think so...the landcruiser body's are longer, but the mini-truck 8" aisin hub body is, I believe, the same body as the IFS.
Or maybe I should just go measure my ifs hubs and SA hubs
But even if they are a little different it doenst matter because they are still interchangeable.

Maybe I'm thinking that just cause the wheel hubs mount the rim farther in on a solid axle than the IFS wheel hubs.... Yeah, that's probably it...
Which is my point. Unless you purchase the gear from Bobby the only other way to get the gear is with a SA hub. So no need to use an IFS body.
The guy I bought my solid axle from had installed Mile Marker hubs on the axle. Can't imagine why anyone would ever do that, I broke them both in a month. Took me a while to find some solid axle aisin hubs, wish I would have known about the IFS conversion. Have not broke a hub since running stock aisins, but need to get the chromoly hub gear before I break a stock one and ruin my chromoly birfs.

Does anyone have a line on replacement parts "i.e... springs, dial,etc. (other than the o ring and gasket) for the aisian hub? I just got a set of IFS' and plan on doing the Longfield hub gear conversion, but may need to replace a part inside.
As I recall, all of the internal parts are interchangeable between IFS and SA hubs except the gear. To my knowledge none of the internal parts are available as separate items.

Do you have a reason to suspect that a part is bad? Usually the hub is either fine, or you need an entire new hub... IE: It's been grenaded... I haven't heard any stories of an Aisin needing a part, and only a few stories of them breaking...
Check the FAQ for a thread on rebuilding the hubs.
