It's a 97. Super easy install - it was tough to tighten everything down - I didn't realize that the gaskets would expand with heat, and the pipes themselves seemed to loosen up. So after around a day of running, I was able to tighten it all down with the magnaflow gaskets and there are no...
Better pictures attached. All in all, I'm pretty happy with the BRExhaust kit for $450 shipped.
Again, for anyone considering this - buy OEM gaskets and hardware - it's worth it.
Alright, installed the Maganflow Y, cats, and the magnaflow BRExhaust. All in all, pretty easy. There are definitely some fit issues. In fact, one part of the exhaust touches the bottom of the cab. Is that a problem?
Tried to take a pic. Will take some better ones tomorrow in the daylight...
For anyone who finds this thread in the future, it was the harmonic balancer. It mostly only made that noise when the AC compressor was on. After reading a few of these that ended with the same problem, that sounds like a common thing.
Based on the condition of the rubber and the lack of oil...
Was this your youtube video or did you find it? I think I have the same problem, and am trying to work through it. Here's a video of my truck - it sounds/looks the same. Notice the voltage go up when it's making the noise. Any advice?
Well, I was wrong about the AC clutch. After a day or so of not having the AC engaged, the noise came back. I replaced all 3 belts, both idler pulleys, and still have the noise. In the second video I posted above, the sound is super clear - it's light a low knock sound that comes and goes...
The compressor is about a year old new denso. The noise only shows up when the clutch is engaged.
I hope it’s the clutch! Any idea on part number for the bearing? I didn’t see it on the diagram
I pulled the belt on the compressor side. Compressor and adjustment pulley spun fine. I can't tell though if the adjustment pulley might have too much lateral play from being worn out. New one will tell.
I guess all that leaves is the water pump or the alternator, right? I will investigate...
I pulled the idler pulley - no effect.
I did run it a bit tonight, and whatever it is bogs to the point that there is visible voltage drop and the headlights dim. Is this consistent with something sticking on the belt and causing the alternator to spin slower? Or am I wrong about that?
