Yeah... sorry... you are out of luck. You cannot install manual hubs on your truck, unless you are going to swap the whole setup for 1998-2001 years.

You have exactly what I had on my Rodeo '02 and I am currently having on my Axiom. Those are drive flanges.

You have two choices:

1) ignore the issue altogether. This is what I did with my Rodeo '02. I purchased it brand new, gradually lifted to 3.5" up front, and drove it till approximately 65K miles when it was totaled. I had had no CV related problems.

2) lower your front differential. Now defunct company "Darlington offroad" was making the kit. I have it on my Axiom. It takes about 1.5" front ground clearance but the CV angles are much better when lifted.
