    2010 Blur LT. Diagnosing creak - Is this gap in the lower linkage normal?

    Trying to figure out where an annoying creak is coming from, and when I was looking at my lower link I noticed that one side has a much larger gap than the other. Is this normal? I never noticed it before, but its possible I just overlooked it in the past.

    Have you ever tightened the pivots?
    Assuming you have the collet style pivots and bearings.
    Tech Tuesday: Adjust the Pivot Bearings on Any Santa Cruz VPP Suspension - Pinkbike

    If you have the older bearing style, you can retorque as well. The process is simpler. With the old style bearings, once they start to wear, you can't tune out the slop and they'll need replacing.

    Do you notice a slight side to side knock if you wiggle the rear wheel/rear triangle?
    That will be slop in the linkage, worn out bearings, or a loose hub. Loose hubs don't usually creak, but loose suspension linkage often will.

    Creaking is usually slop in the linkage.
    It can also come from worn out shock hardware-DU bushings.
    If you notice a slight clunk when you lift your bike off the ground by the saddle, your DU bushings need replaced.

    I have tightened the pivots, hoping it was an easy fix but it didn't do anything. I followed the direction from that video. No knock when I wiggle it side to side, but I do notice a very tiny bit of play when I lift the saddle. Not so much a clunk, but there is definitely a tiny bit of movement somewhere.

    If you've been greasing your pivots and have retorqued them and notice no play, then check out the shock hardware.
    Have you ever replaced the shock mounting hardware and bushings?
    Worn out shock bushings will creak and some VPP bikes wear them out quickly.

    Ill take a look at the shock hardware, didnt even think to look there before. It really FEELS like its coming from the bottom bracket area.. But I realize that doesnt mean anything and the creak really could be coming from anywhere. I only notice it when I put a TON of pressure when pedaling. It will creak and then when I sit on the bike and engage the suspension a bit it will creak until it gets some movement. I really only notice it when I'm cranking hard on steep inclines. But it's a pretty bad sound.

    Is the creak only when seated? I've had seatpost creaks that sounded liek they were coming form the BB. If the sound goes away when you stand and pedal, I'd suggest giving the seat tube and seat post a good cleaning and tightening.

    Hope you find the cause soon, focusing on creaks rather than riding is no fun, been there....

    It's the shock bushings. Exact same symptoms on my blur ltc. Call fox and order the 3 piece stuff. Problem solved.

    From Santa Cruz FAQ on their website:

    It looks like the lower link is off center in my frame- is everything ok?

    Yes- this is correct. With our newer pivot system, the pivot axle draws the link over to one side in order to properly preload the bearings. This offset is accounted for in the frame design so everything ends up nice and straight in the end.
