The sleeve on the arm that is being tack welded is called the drag link. It goes from the strg box to the steering linkage or knuckle. It can attach to a few places, it is make sensitive. We can align those trucks all day long. These tach welds have nothing to with caster, camber or toe. The only time you deal with the drag link is, IF AFTER the alignment, the steering wheel is not straight. As you all know 3 o'clock to 9 o'clock is normal. If the steering wheel is off, you would adjust it to perfect USING THIS TALKED ABOUT SLEEVE. A die grinder will cut these small tack welds on the adjustment sleeve. Normally, they tack the nut or bolt to the sleeve but it can be anywhere. Yes some have tacked the sleeve to the threads. We cut the weld on maybe 1 out of 20 trucks to straighten the strg wheel. After an alignment most of the time the steering wheel is straight. I'm and ASE Master and have been for 30 years.

Before you argue with me, know this, just about everyone in Phoenix has heard, you can't align that truck the adjustments are welded or there is a recall but the parts aren't available yet. This weld does not and cannot hamper our ability to align your truck. This weld just eliminates our ability to re-center your steering wheel IF NEEDED.
