I see you've done electric lockers front and rear. We've been
curious how close the locker mechanism on the side of the diff
comes to the spring mounts on that front axle. Did you have any
interferance problems to deal with? (except for modifying the
housing for the new shape and bolt pattern of the 3rd member of
course)

Also... did you do the normal electric lockers, or the FJ80 high-
pinion versions?

I used high pinion FJ-80 diffs front and rear. The actuator on the front
comes VERY close to the spring, but it was easily clearanced. I now have
about 1/4" between the spring and the closest part of the actuator housing.
There is room for the U-bolt to pass between the axle housing and the
actuator (I have flipped U-bolts). I am using YJ springs which are 2 1/2"
wide, so Toy width would give you a bit more clearance. If anyone wants
specifics for what I did, I'm happy to explain them off-list. (or on-list,
I don't care!)

Sorry, it's not my web page. So, here is a condensed list of the
Mods to the axle housing: Besides cutting a notch for the locker
mechanism, welding a bit to the "ring" where the third member goes in, and
drilling and tapping holes, nothing. (ok I had to grind a tiny bit off the
underside of the spring perch.)
Mods to the third member: There is a "cap" that bolts on to the
side of the actuator, where a shaft protrudes through the casting. It is
held on by two bolts, the upper side needs to be ground or milled flat,
countersink the hole and use a recessed head bolt. (I think its M8x1.25,
approx. 1/2" long, Allen head). Also, there are two bolts that hold the
wiring bracket. One also bolts the third member to the housing. I cut the
mounting boss of the other one off.
That's pretty much all I had to do, aside from recovering from the
near heart-attack I got when I realized the third member I just bought
wouldn't clear the spring.
I would definitely recommend these to anybody--IMHO the locker is
superior to an ARB, the only downside is the cost of replacement R+P's for
the high pinion third member. (that's why I'm still 4.10:1)
I have a reverse cut unit in the rear also. I need it because my
rear driveline is so short, and it has held up just fine. In a heavier
vehicle than my heep, I'd go with a standard low-pinion, it's stronger for
rear-end applications.
