I installed my MM lca's here a few weeks ago and after I installed them I started to notice a vibration when I am driving. It is usually when I am from 60mph to about 67 or so then it goes away. Any thoughts on what is causing this or what I can do to fix it? I have steeda sport springs and kyb shocks and struts but those have been on the car for more than a year now and I never noticed a problem until after the lca's went on.
I have heard pinion angle get an alum. ds but I wanted everyones opinion here first.
Thanks

 

Subscribing. I have the same problem.

 

adjustable ones or no?

 

In general vibrations that occur inside speed windows are DS based and you can fix it by either having your DS high speed spin balanced, or get a balanced aluminum unit to replace it, or try clocking the DS 45 or 90 degrees from where it currently sits in relation to the pinion flange.

what kind of bushings are in the chassis end of the RLCA's? If you have sphericals with poly urethane caps, then you should get used to some vibration (more of a low frequency hum) being part of the package. Still, the DS seems like your current issue. Mine did that and replacing it with an aluminum one from Griggs fixed that.

 

here is what I bought.

it has urethane bushings on the chassis end and spherical on the axle side. I guess it looks like an alum. ds is my next purchase.
