UPDATE:
I decided to go for the Advance TRW trac bar, Monroe steering damper and the DSS.
I took the truck to get the alignment checked today because the steering wheel was off center. To my surprise the new trac bar had movement in it! I brought it home changed the trac bar again and took it back. This time everything is ok. No alignment change just the steering wheel to re-set.
The truck drives better than new! Am I impressed with the TRW trac bar? I am not sure yet. I hope it was just bad luck. The guy at the alignment shop said he has seen this happen before with front end parts. He felt the TRW should be a good bar. I will keep close check on it and see what happens.
