Those are some huge welds!
Unfortunately there are a bunch of different ways to do it. My set up. V6 calipers with tacoma rotors. I went with the tacoma rotors because they are a direct fit and do not require drilling. You will have to mill down your hub bearing housing for the rotor to slip over it but do it once and be done with it. I milled mine down by removing the wheels, placing it in 4 low low, and using a 7" angle grinder on it. I ended up removing about a 1/2 of material but if you keep it spinning it removes it equally. To mount my calipers I drilled my knuckle housing out and used a 1/2" grade 8 bolt with a thread locked nut IIRC. It's actually a very easy mod and I'm really glad I did it. I can post some pictures for you if you want in a couple of days since I have my front end all torn apart and will be putting it back together. I don't daily drive my rig but it's not a trailer queen either. My braking greatly improved and I have had no problems with the system.
I know this thread is old but I figured instead of starting a new one I'd post here.... I know that the ifs Toyota rotors are a little smaller than the 80's land cruiser rotors and the solid axle rotors, and shouldn't be used without a bracket. I would really like to do the Tacoma rotors, but are they also smaller diameter? Or are they about the same diameter as the solid axle or lc rotors? If they are smaller they may still fit but would just have less pad to rotor contact area, which likely isn't a very good thing....Thanks for any info!
Some pics.This is how much farther out your hub is going to be. I got dust shield eliminators.Here is where I am talking about milling it down so the rotor fits over. 1/2" threaded, grade 8 bolts with locking nuts. I also put thread locker on. You don't want these vibrating loose!Here are the calipers mounted up. I ended up having to put a washer in between the caliper and mounting surface to get the caliper centered on the rotor. Washer is also grade 8. I don't see any problem with this set up due to the fact that there is full contact between the washer and the rotor and mounting surface. The tacoma rotor, all stock, no drilling required. This was the main reason I went with the tacoma set up. If I nuke a rotor for some reason I can just buy another one and slap it on, no drilling required. Also the tacoma rotors are a slip fit on the outside. They are not pressed on with the tire studs. They are also vented rotors, I'm not sure if the land cruiser rotors are.
85 axle with ifs hubs turned down,FROR Tacoma bracket kit, 96 tacoma rotor and 96 Tacoma calipers. The instructions from FROR said to flip the knuckles left to right so the ears are on the front but mine were already FUBAR from a failed attempt to tap them so I just cut em off. Also since the Tacoma brakes are in the front of the knuckles you put the left caliper on the right and the right on the left.
are you concerned about the wheel diameter or the caliper body sticking out past the WMS? FWIW, for a short time on a previous rig i ran IFS hubs and 1.5" wheel spacers, with 37" Pitbulls. Yes, holy scrub radius batman...never broke anything though.
I think when this topic went around Pirate4x4, everybody had a lot more trouble with aluminum wheels than steel wheels. Steel wheel centers will be better able to slope away from the WMS faster than the castings of an aluminum wheel (at least i think). With the bigger 4runner/tacoma calipers you may just have to grind them for clearance no matter what. The cheapo 1/4" spacers from the parts store would probably help out and not hurt your width too badly. I'd buy one of those 1" V6 or 1.0625" T100 master cylinders also. edit: looks like the wheels you linked to are aluminum?http://www.pirate4x4.com/forum/toyota-truck-4runner/985436-ifs-hub-swap-confused.htmlhttp://www.pirate4x4.com/forum/toyota-truck-4runner/1267834-ifs-hub-sa-axle-widening-method-writeup-pg-1-a-2.html
You've got it backwards. People are having problems with steelies and not with aluminum.
lol, my bad.
V6 calipers are a nightmare to fit with wheels whenever I've tried to use them. So if tundra are bigger than those, your gonna have a helluva time finding wheels. Just speaking from what I've witnessed firsthand. It's possible I've been doing something wrong.
