Birfield I.D. Question

[turbophil]

I have my front end completely apart now. Judging by the carniage in the knuckles, I'm thinking that a Birf has blown in here before...I've been planning on upgrading everything I take apart, so I was going to go with Longfields. However, the birfs that I took out seems to be pretty hefty, and a previous owner has ground away at my knuckles... Since I have mini truck rotors, I'm wondering if I might have mini truck birfs . Is there an easy way to identify between stock FJ40 birfs and the heavier Minis? If I do have mini's, should I still replace them with Long's?


BTW, the rig is running on 36" swampers and a locked front end...

Thanks,

minitruck and 76-78 cruiser birfs are almost indistinbuishable....slightly longer shaft and smaller bell for the 76-78 models tho.

If they were ground, it's most likely done to fit the minibirfs.

And yes, you want longs....if you have chromo inners, get the chromo longs....otherwise, just get the normal ones for normal stock inners.

also, mini truck and 60 birfs are a tad bit shorter than the 76-78 birfs.

Why is this-- I thought the inners were pretty strong and the outers are the big weak point? I was thinking of getting 27 spline chromo outers and calling it a day...Is this a bad idea?

Thanks!
