My 4Runner doesn't have ABS, thus the 2WD spindles don't have ABS sensors. The 4WD spindles have sensors, so removing them simply wasn't an option unless there was something to fill the hole. The best route was to cut the wire for the ABS speed sensor and leave it in.
4WD spindles:
This is John, the owner of the shop, cutting the shields off of the 4WD spindles.
After removal of the transmission/flexplate inspection cover, some leakage was evident from the oil pan gasket. A while back, before meeting John, another shop had installed a cork gasket that shouldn't be there. The seeping is slow, so I only sinched the bolts a touch tighter and left it be.
4.56 Front diff installed in the 99 with Toytec 1" Diff drop:
This was a real pain to get in, it's a very tight squeeze. One of the tricks that John learned over his course of experience - grinding off a few threads from the bottom stud makes that a way easier job.
Reinstalled spindles, rotors, calipers, and wheels with 2WD spindles on the donor truck, so it'll roll.
The old CV's have bad seals against the hub, so to avoid risking water damage to the front wheel bearings, new ones are on order.
Shop is packed up for night and we'll be back tomorrow!
