Try bleeding your shocks this way and see if it helps...

With the shock body vertical and the shock shaft fully extended, make sure there is a slight bulge of shock fluid higher than the edge of the top of the shock body (add no oil to the caps). Install the cap sans bleeder screw. Install the shock rod end, and the lower spring cup (no spring). Push the shock shaft into the shock body slowly, until the spring perch bottoms out on the shock body. Wipe away bled oil. Install the bleeder screw. Pull the shock shaft down. Install the spring. Install the shocks. Set ride height (and all the usual stuff) and see if that helps any.
