NelsonV | Tightening control arm pivot bolts? | ||

A friend of mine brought up this issue; not something I've ever considered....
http://www.tirereview.com/bushing-tes ... ll-when-a-bushing-is-bad/ Quote: A common error for a technician is to install a control arm, then torque the pivot bolt while still on the four-post lift. While on the lift, the suspension is at the end of its travel. If the technician torques the pivot bolt under those conditions, when the vehicle is lowered, the bushing will be in a constant twist. That condition is a death sentence to the bushing, one that may be carried out at the first good bounce of the suspension. That scenario is not an issue for polyurethane designs. Strut rod and radius arm bushings should be replaced in pairs to prevent great differences in caster between sides. Real or ultra-conservative issue? |

I can see this... had similar problems with RC car suspensions if they were tightened in the wrong part of the arc.

True, autocrossers go to great length, to take all the tension out of the system

Actually - Ultra Real Tightening the bolts with the wheels in full droop is a very bad idea. This also applies to the rear suspension components. And for example, on a C2, if you tighten the spring mount bolts that hold the leaf spring to the rear end housing without the car weight, you stand a very good chance of breaking the rear end housing. And - always use a torque wrench. |

Correct, the factory rubber is bonded to the metal.
I don't get It, because it doesn't seem like it allows for enough movement, and bushing stretch should not be dictating your wheel rate, the spring is much more consistent |
