Lowes- useless. No 1.5 black pipe caps (I have the rest of the black pipe bits already), and get thisd- they stopped carrying taps (not that I was too hopeful they'd have the right size). I cut the head off a 3/4 grade-8 bolt and used a 1/2-inch black-pipe union to join the bolt and a spare open-ended lug nut, brazed with a tight-fit.\ Ground/sanded off the chrome at the coating on the bolt first. Those gold bolts- cad plated? Plenty of air etc when I did it, now the garage is frigging cold.

As I understand it, you pull everything off the front, and the tail shaft and MPT, so the valve body doesn't get disassembled and the internal spinny bits except for the front drive shaft stay in place. I went the used-trans route as you can get one knowing the mileage, and doing the R&R myself it was affordable. I plan on keeping the car long enough it would have been worth $1500 having the one in there repaired, but finances didn't allow.

Lower ball joint time- yay! Detected a tiny bit of wanderlust in the sterring, bit of play in a lower front BJ. I have cleaned the gap to expose the bit of the BJ and threads, heated with the blue wrench and let some kroil hopefully get sucked into the joint and threads. I guess I'll be searching for that homemade BJ puller thread... I will keep the slot doused with penetrating oil, and will heat the heack out of the part the bolt threads into when I pull it. Next week hopefully...

The way to check a hub (if it falls outta the race it's way bad) is to look at the fine lines on it wgere it goes into the race. Fine scratches along the length where it was pressed in/out are fine, any scratches that go around or any discoloring shows the bearing race has been moving on the hub. It's not so much that if it rotates the rotation will damage the bearing, but that if it rotates the inner race will not be held perfectly centered and the balls/rollers and race contact points will be overloaded, too few balls/rollers will be taking all the load. When they get overloaded they fail quickly. Also, if one race spins and the other does not spin with it, the face where the races contact each other will wear and the bearings will at first get too much preload (axle stretch acting like a spring), then as it wears they'll get too little.

The TCU and much of the car harness are different for VDC. You can put a VDC trans or just the rear bits into a non-VDC car, you just need to control the lockup clutch manually. The mpt in the vdc trans is designed to be locked or free, not to be partially slipping. It is the same size in diameter as the non-vdc MPT but has fewer plates.
