Began disassembly of the front end on the '99. All part of putting in the new e-locker (Harrop/Eaton) 4.88 front diff. The 4.88 rear diff went in last week.
So yesterday, the front diff came out. I was able to do this my just unbolting the LBJ's and undoing the outer tie rod ends, then using a ratchet strap to lift the hub up and off the ball joint. Then pop the sted ends out of the diff, and swing each side out of the diff and out of the way without undoing the outer end of the CV (which is a bit more tedious with the manual hubs).
That's just step one, while the diff is out I'm using the opportunity to correct some minor oil leaks while I have the easy access. The steering rack has begun to weep fluid out from around the steering shaft, it's getting replaced with a new Toyota rack. Also, the oil pan is a bit wet in some areas around the perimeter, it's coming out for a cleaning and resealing with FIPG. And the oil cooler is getting new o-rings and coolant hoses, it's a bit damp with oil around that area.
I also have a new passenger motor mount I might as well put in while the access is good. The driver mount was broken a few years ago, I bought both and replaced the broken driver mount then, but didn't feel like replacing the passenger mount at that time. Might as well while I have better access from underneath.
I got a non-ADD passenger front diff leg from a Tacoma in a local PnP junkyard, so that's going on the new front diff. ADD isn't needed with the manual hubs, it's just another thing to possibly fail out on the trail.
