help with steering shaft

ok so i have a 70 nova and im having trouble with my rack and pinion install the rack install is fine but when i install the steering shaft to connect the column to the rack it turned good and smooth but when i connected the tie rods to the spindles it now felt choppy i read up a little bit and saw some stuff about mis-phasing the u joints and i dont know if its better with the anchor for the upper part of the shaft all the way in or out... if any of u guys have any experience with this i would appreciate the help thanks in advance

This would indicate the joint phasing is correct, how does each spindle turn by hand?

Woodward says to keep the angle below 20, split it between two if necessary. I'm guessing you know about using paired joints (from wiki ):



And proper phasing:

i have the unisteer steering shaft kit and it comes with a frame mount for like a heim joint and a bracket that bolts in place of your existing steering box bolts...it looks like the bottom u joint is the issue because the angle is pretty severe ... and with the heim joint threaded all the way out it still seem pretty radical plus thats when i start having header fitment issues

Just for an example, here's a pic of the relocated steering shaft (header clearance) on my S-10. It, too, has two joints with a Heim support.

You might want to take a close look at the U-joints and make sure the shaft is not so long that it hits the cross. That will make it feel choppy for sure. How do I know this.........

i got a chance to play with it and the phasing of joints and i got it just right ...its unbelieveable how sensitive that steering shaft is... it was only off by maybe 2 or 3 teeth on the splines once i put the grooves on the u joint at a perfect 90 degrees it was smooth

choppy rack

pull back the rubbers & check that theres nothing in the threads or the worm , if its all smooth until you connect the tie rods check them,Disconnect & try one at a time in case theres a problem one side
