"one" of the biggest problems with rubber unis (apart from oil stuffing them) was the fact that soooo many people would jack the car up,,, change the unis , tighten them up with the wheels hanging down,,, then lower the car back onto the ground

now this makes the unis "Constantly" twisted up, the entire time, from then on

the trick is to have the axles at std ride height (as if the car were on it`s wheels the ground) & tighten them up then

this way the unis are in a relaxed state & can happilly last for as long as they were intended to

so,,, there you go
