The suspension on the rear of my car feels really loose while driving. The car will just kind of drift from side to side at highway speeds. I'm positive it coming form the rear and not the front end. I jacked the car up and checked everything and nothing is loose or obviously damaged. My suspension mods are strano springs with Koni 4/4's, rod ended LCA's and rod ended panhard. What could be causing the car to drift in the lane like it is?

 

Are the lcas the same length? Like is the thrust angle in the rear centered?

 

I had NTB do an alignment about a month ago and according to the spec print out its good

 

Just making sure that your rear wasn't cocked in there a little crooked. How old are the shocks?

 

If the rear of the car feels like its moving side to side that sounds like a PHB issue to me. You getting any noises from that area?

 

The shocks and springs were installed early Jan. and have maybe 2500 miles on them. I'm not getting much noise from the PHB but i did find that one of the rod ends is seized and doesn't swivel in the socket like it should. I don't know if that would cause the problem though.

 

Push down on the back of your car in the center. See if both sides go down evenly. If not, you may have a binding issue on the shocks, causing your whole suspension not to travel correctly. Just a thought

 

I tried pushing down on the middle of the rear and it looks like its going down evenly. There is a clunking noise when i push like something is loose but everything is tight.

 

Can you post the numbers.

 

Sure I just need to find the print out.

 

What are you shock setting at? I tighten them up to compensate for temperature and wear. Go up a 1/4 turn and see how it feels. That's what adjustable shocks are for.

If my shocks are to soft, the front feels loose, and the rear seems all over the road.

After you feel the changes, balance the fronts to the rears to dial it in.

 

Did you just put new tires on it, possible worn axle bearings, are all the lugnuts torqued to spec, have you changed your normal tire pressure?

 

the tires are good and all pressures are normal. The rear end was rebuilt about 2 months ago so all thats good also.

 

I can't remember what my shock settings are at right now. I guess I'll try adjusting and see if that helps it out any.

 

are your swaybar endlinks good?
