I recently got in a little fender bender. I just picked my truck up from the collision repair center and when i dropped it off it was mechanically fine, no out of the ordinary noises just a messed up bumper. I picked it up today it sounds terrible.

Here is a link to the video i took of it

any thoughts on the problem or troubleshooting ideas would be appreciated

Sounds like a pully is grinding against something. Could be wrong, but thats what it sounds like.

Hard to tell about the sound from the video. Did your front bumper get pushed in from the fender bender?

What pulley was causing that? Did you just replace the bearings :dontknow:

I do not remover which of my pulleys was making the most noise but I changed 3 of the five and that they did not feel bad when I spun them by hand. I finally after checking several times felt a little ruff ness when I turned it slowly and only felt it for a second an it went away and it seamed to spin smooth again. I did this over several days. I think the two side buy side and the one on the tensioner.

Well finally swapped out the bearing in the tensioner pulley for the NST kit... Microblue FTW!:top: I placed the pulley in the oven at 350 for 20 min and the bearing literally fell out. The micro blue after packing with grease dropped right in being still a hot pulley. Luckily the other pulley on the nst kit is easily able to clean and regrease... that bearing is nice not having to remove the pulley. I recommend anyone, to regrease these two pulleys. Truck sounds good again.... crazy how one pulley grinding sounds like the blower is falling apart.

To keep costs down, the bearings in the NST kit were spared in cost. Meaning cheap bearings which wouldn't last long. Been documented and known for a long time, but slightly masked in the past. Either way, glad you sooved it and fixed it.

Yeah... I remember years back when everyone was talking about it. Thought I'd bring it back for attention. Lucas oil green grease seems to be working well... May disassemble my blower since its coming up to 50,000 miles and clean up there too and install the plastic coupler everyone raves about.:top:
