Ok so you can see what i drive in my sig. but my question is... This is the second time ive had my belt tensioner replaced twice on my truck... under warrenty. but everytime this squeaking noise comes back. it sounds like im driving an 89 civic with 300,000 miles on it. i no its the belt tensioner. because ive done several tests of my own. but this is were i need yall's input. should i take it back to the dealership and have them replace it a third time? or should i try to put some kind of lube/oil on the spring assembly. if so what kind of lube/oil do you reccomend...
ps: it does it when its cold and hot outside. and dosnt go away even after 30 min-hour of driving.
thanks alot.
