Question,

I have come across a set of Aisin hubs that do not have the bolts cone washers or lock washers that attach them to the wheel. Are these parts already in there with the ADD hubs? Could I get these from a deal cheap? I have a 94 4runner with ADD and am looking at doing the Aisin manuel switch over.

They may be there. The dealer gets about $5 each cone/stud package (times 12 to do both sides). I bought my own bolts at ACE to mount the cap on the hub.

The studs are in your hub, the cone washers and flat washers and nuts are on your ADD flange. So If the hubs are complete (hub body and hub cover w/selector knob, all bolted together) you should be set.

Awesome thanks guys. Now I just need to find another set. The ones I were Eyeing were on Ebay, and somebody just snatched them up. Oh well I was planning on waiting till spring to do this anyway, its too cold outside in Utah to do em now, and I would probably drive around with em locked most the time anyway. Gives me plenty of time to look. That yotayard quoted me 40 bucks a piece for them.

Just be sure to get the right ones. The hubs from '79-'85 solid azle trucks/4Runners will not fit your '94. '86-'95 will all fit fine.

i just did the swap, it shouldnt take you much more than 1-2 hrs. 1 banana job.

Question I popped off the cover for the ADD hubs and had a look at it. How do you get that little gold cap off?

leebee

are you refering to the dome shaped cap on the very end of the hub? if so, just take a bfh and flat screw driver and tap around the edge of the domed cap where it joins the main body of the thin hub cover. once it starts to separate, you can pry it off. then loosen the nuts to the thin hub cover, DO NOT REMOVE THESE NUTS! take the bfh and give the main part of the hub a good wallop at each stud location to loosen the cone washers. you may have to smack it pretty solidly several times for them to pop loose. once the are all loose you can remove the nuts, washers and cone washers. instll your manual hubs with either oem gaskets or some people use rtv (?) sealant. torque main body nuts to 23 ft/lbs and cap screws to 7 ft/lbs. you shouldnt need to add any grease but inspect in any case.

Are you sure about that? First time I ever heard that there was any difference.

johnnyutah36

Thanks Leebee that is what I was looking for. You gotta love the bfh!!!! Best tool I have ever owned lmao.

Flamedx4 I have read that in many places. I will make sure I get the IFS hubs when I find a decent price.

Flamedx4

Good thing I found out before I bought any! THx.

I think that there is a 1.5" of difference per side in-between the 79-85 solid and the 86-95 ifs hubs. Some people do a switch on the solid to ifs to get that 1.5"s instead of wheel spacers.

PAhydrohead

I don't know about the 1.5" but there is definately a difference in spline count. I bought a pair of used 30 spline Aisins and they DO NOT FIT! 2nd gens have a smaller spline count. I found this out too late. Anybody need a pair of 30 spline Aisins?

Yoda

How many splines does yours have? I have a set of aisins that I bought off ebay for my solid axle. They don't fit on my axle (wrong splines). I'll check with my buddy and see if they fit his IFS. If so, do you want to trade the center gears? (the housings are the same...just the inside gear is different)

PAhydrohead

They are definately 30 spline and that is supposed to fit a solid axle but I was told from the person I bought them from that he took them off a 4WD Toyota van?

When I tried to install them last night, the hub housing slid on until it was about 1/4" away from mating up flush with the axle assembly. WTF I thought. Then I noticed that the entire wheel assembly was free wheeling (not turning the axle) no matter which position the hub was in (locked or unlocked). Well the hub can't turn the axle if the splines are different sizes and don't engage!! Duh

Yea, I would be willing to trade center gears. According to my info the 2nd gen IFS needs a 27 spline (edit 26 spline) gear.

Yoda

My buddy just bought an axle for his IFS. I'll see if it is correct for his splines.

PAhydrohead

Somebody else suggested a screwdriver and hammer. I have found it is much easier to use a small pipe wrench. The cap just spins off with one slight turn of the wrench. The teeth of the pipe wrench bite into the cap a bit and mark it up but I'm sure beating on it with a screw driver does the same thing.

Separate question:

Does the small gold bolt and washer that goes on the end of the axle get re-installed when you put the manual hubs on. Doesn't look like it serves any purpose with the manual hub.

leebee

you can work your way around the add flange with the screwdriver/hammer combo. the washer and bolt do go back on.

I don't know what I have, but is does NOT fit the IFS axle. Crap!!

PAhydrohead

Yota,

Thanks for checking, anybody else have a pair or 27 spline (Edit 26 spline just counted and got a set from Cebby today) Aisins they want to trade for a set of 30 spline??

Man I have to get some manual hubs on quick! I swear, as I'm driving around town, it feels like the front tires are skidding/sliding whenever I drive over one of those steel plates that separates a bridge deck from the normal road surface. With the snow we just got, I feel the same thing on snowy/icy patches. I must have a LOT of resistance in the front driveline now that I added the BJ spacers to have the wheels skid on slippery surfaces. Anybody else notice this?!?
