Things have changed !
After 50 years of swinging a heavy hammer and using a Impact wrench, my right Shoulder and Arm is wearing out. Working above is killing me and at the end on the day, ouch!
So...depending on the job, I'm being very selective on what I put on the lift. I prefer taking in bench jobs, Differentials and Transfer Cases. Bench jobs gives you a complete clean or painted unit.

Caliper Pins, What do they do and what's the big deal?
Caliper Pins affect so many things. The Major job of the caliper's pin is to allow the caliper move either way so that the Pads have equal pressure on both sides of the rotor. NOW, Let me list all the things that are damaged when the pins don't slide freely.
1. If a caliper pin or pins are seized, than the one pad will wear more than the other side. Sometimes the pads will wear at an angle, thinner on one end and thicker on the other.
2. If a caliper pin or pins are seized, the pads won't release correctly and cause the rotor to overheat.
3. If a caliper pin or pins are seized, One side of the rotor will be thinner or have a big groove than the other side.
4. This is a big one. I see this mostly on Jeeps. The axle bearings were not designed to handle side to side movement, mostly straight. The bearing is held together by the outer portion of the seal that presses against it in the housing bore. There are 3 parts to that bearing, the bearing and inner race, the outer race and the retainer ring the the seal pushes against. If the caliper pin or pins seize, the caliper pistons will push outward against the rotor. You might say, So What!
Well, the rotor is located on the axle shaft. The axle shaft is now being forced towards the outside. Now the bearing's rollers are forced against the skinny weak retaining ring. The ring is destroyed and now you have a loose bearing and a leaking seal. Leak long enough and the ring & pinion start wining.
5. One More Big One! On C-Clip Axle Models, the same thing happens as before, but ! , now the axle moves outward and extreme amount of pressure is put against the side gear, in turn the carrier, in turn the carrier bearing. If it's the right Caliper, the carrier is forced to the right and the ring gear wears into the pinion gear.
