Anyone ever do this?

Turns out my Ebay "JDM FJ60 FF" is actually a 45. Found that out from the kind folks here. The spring perches are 2-5/16" narrower than a 60, & can theoretically be moved.

It appears that I could make up the difference in track width by using IFS hubs, which put the WMS 1-1/4" farther out each side. Then what to do about brakes. I've been considering 60 calipers & a park brake on the pinon shaft. I know I could make caliper mounts for a 60 FF by cutting up a front knuckle, but this thing has 8 holes on each flange & I'd imagine the rotor would be farther out with the IFS hub & probably wouldn't match up.

How crazy is this? This is supposed to be a DD and possible long-distance rig.

Think I'm about cured of Ebay.

True. I put a 60 axle in my 55, moving the perches is no big deal. I wouldn't want a 3" narrower axle though.

Incorrect. The only way you could run IFS front hubs is if you get new, shorter axle shafts and run drive flanges. The FF hubs are longer than any front hubs.

If it's an older style axle, you could do something like this: http://www.employees.org/~dirttrak/r...conversion.htm

I have a chevy conversion on my FF, but I would probably rebuild the factory drums if I was to do it again.

I think I would personally get the correct rear axle, however others might say just bolt some 1.5" wheel spacers and call it good.

I thought I clarified the hub question in the first thread? The IFS, or any other front hub will not provide the right length from the flane face to the diff unless you want to get custom axles made.

If you have to use this axle, put wheel spacers on it. Personally I'd just by the right housing.

Have you already bought this? Maybe you can trade or resell it?

If the IFS hubs fit (bearing surfaces spaced same distance), would not the outer face (with the studs for the hub clutch) be at about the same distance from the other end as the 45's? I've never looked at an IFS hub. What years would we be talking about? With locks?

I'd already looked into custom axles assuming I had a 60 FF, so this would force me into them.

Mark -
I bought this (with the front) about 2-1/2 yrs ago, so I doubt I can get my money back. I've already put a thread in the 40-55 forum about it. Ad is next.

Whats wrong with a 45!?!? I would be happy to have one over a 60, i mean i know its not what you thought you were getting but still.

**edit** Im a dumbass, i thought you were buying a 60 and you ended up with a 45, not just an axle, my bad.

The bearing surfaces are the same, however the hub itself is physically longer (about 3/4") at the outside due to the bearing retention mechanism (a ring held by two pins instead of the two large nuts like the front end).

In order to use the IFS hub, you'd have to use the large nuts like the front end. There still might be a problem as well, since the rear spindle is about 1/2" longer as well in order to compensate for the locking ring. (I forgot about this in my first post.)

So you could run them, however you still might find some interference due to the longer spindle, which could be sticking outside of your hub. At that point you could grind on the spindle (removing the inner axle seal surface) to run IFS hubs, but you'd be monkeying shit up like crazy because it was the incorrect axle in the first place.

So, there are two thins you could do: Get the correct axle with the correct width, or run wheel spacers. Wheel spacers are a bandaid to a easily solveable problem- sell the 45 axle and get the right one.

It is not the wms of the hub that causes problems for you. It is the face where the axle flange (in the case of the FF rear axle) and the locking hub or drive flange (in the case of the front axle). This face is not spaced the same.
