Going down the road between speeds 40-65, I get a shake of the truck like i am going over multiple speed bumps. Its bee goin on since i got new track bar. Now it fell like im going over rumble strips, but not all the time. Any idea..

make sure your trackbar is tight. did you get an alignment after you installed it??

yes an alignment was done

Ahhhh...........the dreaded death wobble. Many a thread on this for you to search. Shocks and DSS solved my OEM DW woes.

luckily ive never had DW (knock on wood) but check and double check that the track bar is tight!!!

yea im goin to school and puttin it on a lift and checking it. also searchin the other threads

tighten the trac bar and make sure your tires are balanced.

might want to check the alignment again if that didnt work. They might not have done it right
