I installed KG/MM DR21 springs a couple weeks back but did not preload the bushings before I tightened the A arms down....is this a big deal?

Thx

 

Heres what I've heard...

The bushings will get worn out quickly and handling will be effeted in a negative way. I would assume it might also mess around with your alignment. It's such a simple task, why not just do it?

 

What's the procedure for preloading them while the car is up on jackstands?

 

Yeah, would like to know too.

 

If you tighten the components while they are drooping the bushing preload will be opposite the desired direction with some small impact on handling.

The correct procedure is to fully support the corner being tightened with the suspension before torquing to spec. While the car on on stands I put my jack under the lower control arm (using a piece of wood to protect the castle nut) and raise the corner.

 

Done. Thanks all.
