noise after ajustable control arm install

[mustang1994bob]

I just got my adjustable control arms installed and its great, but I’ve got some noise that I’m worried about, I know that bumps in the road are gonna be louder and all, but I can now hear and feel my gears at different speeds (its kinda like a vibration) and I’m wondering if that’s normal noise that I only hear now because of the urethane or do I have something in a bind because of an incorrect adjustment with my arms? (I pulled the diff pan and didn’t see any issues with the gears that were obvious and they are still the stock 2.73's that ford put in)

when i installed my MM adjustables my draveshaft was hitting my E brake bracket. check to see if there is a scratch in your driveshaft or that bracket.....its worth a look

To a certain degree it is normal since harder bushings will transfer more noise and vibration through the car. I wouldn't be too worried about it, especially considering you still have a stock rear end.

i think you're pinion angle is off,

^^^Ah, good call. I was thinking adjustable spring perch, yeah if they're adjustable length ones you could throw the pinion angle out of whack and cause some noise.

No noise hear. I got ones with a ball bearing joint to avoid that.

the wrong pinion angle will make all kinds of noise for you to listen to I have mine setup -4 degrees and it will drive you nuts
