Sway in rear

[X3N0N]

I got a sway in the rear of the tahoe when traveling speeds of about 45+ MPH. Feels like the rear is going to swing right out from under me. For a better explanation, it feels like when towing a trailer and the trailer starts swinging back and forth and starts to get away from you. The 2dr tahoe has 3" body lift with rancho shocks. Recently replaced the sway bar links and the front end is good. Tires are also in good shape. Thoughts?

How about for broken springs or other components? Also are tires same model and pressure same from left to right, front to back not just visual condition. Other possibilities are your axle is off track which an alignment check would find, a twisted sway bar or a defective shock assembly.

All tires are 305/70/16 Goodyear wrangler silent armors with all pressure set to around 35. This condition kinda of popped out of no where. One day it was good and the next day i had a huge sway in the rear. Have not been off road recently either. Guess i can go get my alignment checked but don't see how my axle could be off track.

You would be very surprised to see some of the random shit that these things can pull with absolutely no warning.... I'd get your alignment checked.

Also, is there any history of collisions/accidents on the vehicle?

Loose any huge wheels weights lately where the oscillations might amplified into swaying.
