Changed the torque arms...
 

Holy CRAP did it make a difference in handling/smoothness!

If you guys notice that the ass end of your truck feels loose and clunky, change BOTH torque arms.

I really noticed stability in ruts and going over railroad tracks.

I drove down the interstate for one mile without a hand on the steering wheel, and it went dead straight.

what kind of truck and year. if i'm on old pavement that's really rutted, they throw me everywhere.

99 volvo.

would you know the best way to monitor the tread wear on the steer tires? by just a visual check, it will be too late when you notice a differance. i just have a hard time with the depth checkers getting a good reading all the way around.
