Idler Arm-04 Blazer Zr2
 

I have had three alignments done in the last several weeks and I keep having issues. I am finally going to replace my idler arm this weekend. The truck was just aligned last week and the alignment is alright. Will I need to have it aligned again after I replace this part? Or will I be good to go?

No alignment needed after idler arm change.

...Most shops won't do an alignment if the front end is not tight...leading me to think your idler arm is OK maybe.

Is it the truck alignment that has issues?
