Well the lower control arms came in and look marvelous. It took me 4 tries to bolt them in however, as I did not realize that the U bolts that hold them into the cross member are one long, one short, and have a left right orientation. It took a minute to figure that out, so if you take them out please make them left-right-front-rear so you can get them bolted on with one try.

Cost on the cutting and welding of the lower control arms for the new ball joints was $200 from a local fabricator.

Bolting the spindles in with the upper and lower control arms was a snap now that the correct ball joints were installed. But another problem raised its ugly head. This one is involving the tie rods that hook to the spindles. In the stock configuration the tie rods bolt in from the top of the steering arm on the spindle, but on these new spindles the hole is drilled upside down requiring the tie rod to be bolted from the bottom. This situation will cause a severe case of bump steer. (bump steer is when you hit a bump and the van wants to steer you left or right unexpectedly without any input from the steering wheel on your part)

This situation can be solved one of 3 ways
1. Drill the hole of the spindle out to accept bolts and use heim joints
2. Find tie rod end that dip down and lessen the angle
3. Drill out the spindle hole and use an insert "swedge tube" that will reverse the tie rod orientation.

I am going to talk to some folks that know a lot more than I do as to what to do. Will be back with the results.

I had a "bump steer" on my 4X G30 and the fix for that was dual stabilizers...

I had a conversation with my machinist and he said that we can rebore the holes for the tie rod ends so that they point down rather than up. This will lend to a factory geometry so as to eliminate the possibility of bump steer.

Interesting enough, the tie rod holes are actually SMALLER than the van tie rod studs. Not sure why they made the ball joints larger but then went with much smaller tie rod ends. Seems counterproductive to me.
