Proper way to seat rear springs?
I've been reading and searching for 2 days and nothing helpful appeared.
So I replaced my rear end in my car last week, put new shocks on, new swap bar bushings, installed my LCA's and panhard bar. But when I'm shifting the back end "shifts" to the left.
A couple of people told me I need to "seat" my rear springs, but did not elaborate on how I am suppose to do this. Unless someone has other suggestions on why my back end is swaying after shifting into each gear. And no, it previously didn't do this.

Sway bar is right.....
But what do you mean by load? Guess I didn't do this.

Jack the rear up until the springs are tight or until you just start lifting the car up by the rear or put the rear tires on ramps. Then re-torque everything to ensure it is still to spec. What you are doing is essentially mimicking the load it could be put under while driving tightening everything down with the suspension unsprung or not under load can result in everything not being as tight as it should with a variety of other problems.

Using a torque wrench so you know it is tightened to spec would be the best plan if you have one.

Pretty sure most of the suspension stuff gets torqued to around 75 lb.ft.

let me ask you this just because I'm curious......how do you know the rear is shifting to the left if you're driving and shifting it? That rear has mulitple contact points that should keep it from moving around like that. LCA's, panhard, and sway bar. Do you have the stock or adjustable panhard?

Pan hard bar is the primary link to stabilizing the shifting of the rear end laterally. LCA's control front to back, and the torque arm controls rotational movement. I would also ensure your PHB is tight and that a bolt hole has not elongated causing slop. Could just be that this happened coincidentally at the same time as installing other suspension components.
Boost gets you laid, unless your name is Jon.

that panhard mounts from the back of the rear up to the frame so it really shouldn't be moving around like that unless something is loose or elongated like Jon said. Just tighten the shit out of everything when you put the new panhard in there.

Sway bar nut was loose on the drivers side.
LCA bolt on drivers side body was almost gone. Only hanging on because it got wedged between the body and LCA.
LCA bolt on drivers side on the rear end was loose.
Panhard bar on passenger side was entirely loose.
Springs were tilted. Rotated to a certain position that I read on ls1 how to.
Went for a test drive and holy cow, NO more issues.
Oppppps.

I know. But it was to a point were I was worried and knew I had to crawl under there.
All good now. I'm torquing all that crap down Saturday while it's on the lift.
