Hey guys,

So, I have a 1990 4runner, with an 85 front end. My wheel bearing went and upon closer inspection I guess it took out my hub.

So my questions are this:

I have V6 calipers and can get V6 hubs and rotors for $40, is that all I need? Can I use regular spindle bearings and I'm good to go?

or

Am I just better off buying a new hub and putting it to the somewhat stock it was before?

[cheers]

Basically yes.

But use use an older fj rotor I believe.

That's something that's not very clear to me either, couldn't I just use the V6 rotors? the bolt holes are the same, and the thickness of the rotor would be the same. Also I wouldn't have to drill out the rotor itself.

I have 89 v6 calipers and fj rotors on my 82'.

No mods. All bolted together.

They v6 ones might work. But something is telling me there is a difference.

Fj rotors and any ifs caliper (v6 or 4cyl) will give you vented rotors on a solid axle . Depeding on the year it is literally bolt on like dirka said


About the hub , you need to clarify if you are talking about the wheel hub, where the wheel bearings are or the locking hub.

The inner part of an ifs locking hub has different splines so it will not work

The part you turn to lock is the same

If you are talking about the wheel hub you need to buy a kit or use tacoma rotors and modify the knuckle for it to work. This will give you a wider stance to match the rear.

awesome, what about the hubs, like these http://www.trail-gear.ca/axle-housing/pickup-4runner/solid-axle-hubs/. Are they the same, with both ifs and solid axle?

No the spacing of the wheel flange is different by over a inch I believe
Ifs spaces the wheel out farther
To put ifs hubs on a straight axle you have to bolt the caliper to the other side of the mounting lugs just get the ifs hub there's lots around

Need a small spacer to space center the caliper on the rotor. I used a flat washer. I also drilled out the knuckle and used a nut and bolt

The ifs rotors are a smaller diameter. The Landcruiser rotors are the proper diameter.
No need for spacers. Just put the ifs wheel hubs (with wheel bearings inside) on the solid axle spindle. Bolt the v-6 caliper (or 4cyl ifs caliper if you're a cheapskate) on to the other side of the mounting ears. Drill out the threaded holes on the caliper for I think a 1/2" bolt. Bolt it together, and you have a solid axle that is the same width as ifs (3" wider than stock solid axle)

I have run this setup on a few different axles with zero problems and awesome brakes.
