3rd gen elocker axle housing in a 2nd gen

Register to hide this ad
You can easily make the 3rd fit in your existing housing. Takes a little work with a cut off wheel but not too bad.
There are a few good write ups around

Make sure to test the motor and it's the same gear ratio as your front diff
 
I'm I correct in saying that the axle splines are different? 1st-2nd gen have 27 splines and 86 and up are 30?
 
Does the 3rd gen 4runner axle housing bolt into a 2nd gen 4runner?

IDK if it's a direct bolt-in, it's 2" wider and IIRC the coil mounts are spaced differently.

Toyota Rear Axle Widths:
55" wide, '79-85 4wd trucks/4runners - 6 Lug
58" wide, '86-95 4wd trucks/4runners - 6 Lug
56" wide, '79-95 2wd Trucks - 5 Lug
60.75" wide, '95.5-up Tacomas/4runners
66.75" wide, '93-98 T100 trucks


Does the 3rd gen complete axle housing bolt under a 2nd gen??
Bust out the
tape measure

what are you plans for wiring? getting the ORS harness?

as mentioned earlier the swap into a non elocker housing isn't hard

several people have reported getting by with just griding the notch and not tapping the two holes there, just applying enough RTV to keep it from leaking

wasn't aware of any differences. I put 94 axle shafts into an 81 third..
pretty sure you are thinking of the spline count on locking hubs from a straight axle being different from IFS hubs
 
So the axels from ALL the Years are 30? I was reading it as the 95 and under were 27 spine axels and pinion. but they are acually 30 axle and 27 spline pinion?

As far as the wiring I haven't decided yet on which mfg to use. The ORS harness looks like a winner with the option of the OE switch. I hope to drill and grind this weekend. I dont want to screw up the drilling and taping as its one and done. Tight tolerances on the 2 long studs.
 
Finished the drilling,tapping and grinding the housing. Now its time to finish building the diff. So far so good.

From what I've read the 3rd gen axle housing is slightly wider. I don't know of any other differences and haven't compared the two side by side. It would have been much easier to simply swap the complete axle housing so I'm assuming there must be additional differences.
 
Finally finished the elocker mod. I missed the info on the ABS speed sensor and the rear sway bar. The mechanical and electrical went really well and it works perfect. Now its time to address the rear ABS light and the sway bar.
 
No go on the sway bar. Running without one. I cant run the abs speed sensor either so I took the easy way out and removed the bulb. So far driveability and has been fine.
