I finished up the 4.30 front diff install last night. Again, a huge thanks goes out to all of you for offering advice on the bent flange. I can't thank you enough.
Lifting that chunk of iron is much easier with a little help from a friend.
The rearward diff mount is absolute proof that Toyota engineers hate Toyota mechanics. And those bolts are supposed to be torqued to 80 ft/lbs. I had to use my highly calibrated torque elbow on those.
All done.
All that's left on my e-locker retrofit is to create and install the wiring harness.
I'll be using the elocker ECU and OEM switch from the 99 4Runner that the axle came out of. 4Runners up to 2000 had an RR Diff Lock indicator in the instrument cluster even if it didn't come with a locker. In 2001 and 2002, there was no option for a locker, so the indicator on the instrument cluster was removed. With some research and help of others that have done this before, I'm going to wire the OEM switch's light to act as the indicator.
In the stock form, an elocker can only be used when the truck is in 4lo. I'll be wiring it so that the locker can be used any time; 2HI 4HI or 4LO.
Some retrofits grounded the speed safety switch so that the locker could possibly be activated at any speed. I will be tapping into the 4WD ECU's speed wire to keep the 5 mph speed safety in play. I don't want any accidental locker activations at 70 mph on I-24.
Here's the wiring diagram I'll be using. Now, where's my wire I ordered, USPS?
