you can try tightening the bolts, honestly I dont think you will be able to make much of a dent without a 3/8ths impact, there is not much room to get a swing on a rachet. None the less, if that doesnt help you get the whole shaft (from the base of the steering column to the steering rack). Its typically not SUPER expensive... Again if you have someone to rock the wheel for you you can feel the slop in the joints before you waste a bunch of time and money on this lead.
Swinger... no grad school is a better choice... you will have the bank roll to pay schmucks like me to fix your problems and my only saving grace is ill be poor the rest of my life but never have to pay the man to fix my cars
how in the hell did you get a breaker bar on your rear UCA nuts? I could hardly get a ratcheting wrench in there. I would double verify all is tight, The first place to look when a problem starts after a "repair" is the repair naturally.
