Trying to diagnose rough ride
I have been having issues with a rough ride in my DD 2002 T/A. I bought the car recently as a DD and it wasn't in the best condition. It had 94k miles, lowered on stock shocks and eibach pro kit. The rearend broke shortly after buying it. I took the opportunity to fix multiple things at once.
-rear rebuilt with ratech deluxe gear install kit. did not replace gears.
-replaced one of the axles (not sure what brand, mechanic ordered it)
-replaced shocks and springs with SLP eibach/bilstein kit
-replaced rotors and pads (cheap stuff from ws6store)
-installed adj panhard bar and LCA relo brackets that are set to the lowest hole (founders)
I just got the car back and decided to drive it to a conference this past week. At interstate speeds (75-85) I am getting a very constant bounce. Like the kind that rattles your teeth. Where do I need to start if I want to eliminate this problem?
Wheels are c5z replicas 17x9.5/18x10.5. Nexen 3000 275/40r17 up front and Nitto Invo 295/35r18 out back. Tires have about 7k miles on them. I think I'm running either 32 or 36psi all around.
Thanks

Tires were balanced when they were installed by discount tire 7k miles ago. I also had the car aligned a few weeks ago when I got the shocks/springs installed. Would they need to be rebalanced after changing the ride height of the car?

Shocks and springs were brand new from ws6store. Wouldn't the car be rough at all speeds if the axle was bent? It's smoother at 120 than it is at 75-85. It's also really smooth at low speeds. Just rough at interstate speeds. Highway speeds are fine

sounds like a wheel is out of balance. that is the sweet spot for slight out of balance. it a inner wheel weight was scratch and material was removed, that could to it. that happened to me when i took the wheel off to fast, it fell on the rotor and removed some of the weights material, had a vibration from 55-65 till i rebalanced them. it is a cheap fix, i would just get them rebalanced.
