    <25k miles but I'm on the d3 springs. Could the springs have caused the shocks to go early?

    I'm guessing check everything on the front end and if nothing is obvious, replace shocks.

    Does this make sense or should I change my approach here? Anybody know for a fact what tends to go wrong with this car when there is bump steer?
    Shocks are very likely toast. Mine has been lowered for around the same amount of time and both my front shocks were junk. I bought the kybs on amazon for $100 each and the clunking from the front and rear are almost all gone.

    The spacers in the rear shocks keep them in their stock operating range and mitigated the damage the front ones experienced. Rears are still good.

    Re: Knocking noise in front end going over bumps

    Alright thanks Tim. Based on this thread,

    http://www.cadillacforums.com/forums...ement-kyb.html

    This is the one I found:

    http://www.amazon.com/gp/aw/d/B001C4...6262803&sr=8-1

    Is that right?

    Any comments on the kyb vs oem or basically no real difference?

    That's right.

    Feels is same as stock. I can't tell the difference. No use going with OEM if they are only going to last 25k anyway.

    Everything seems ok down there. Shocks it is. By the way I also noticed slightly accelerated wear on the outer edge of the front tires. So right edge of passenger front tire and left edge of driver front tire. Rears are fine. Could this be related to the shocks? I always thought shocks would wear the inner edges.

    It's also very possible that it's time for another alignment now that the d3 springs have settled some more.

    Please advise.

    I had the same wear on my fronts. Just the outside edges. I bought new tires, and I had the alignment checked along with all the suspension and everything checked good. So we will see if the new tires wear as bad. Im hoping not.

    Im hoping it was just my driving habits
