For the longest two months of my life, I could not figure out what was clunking that appeared to be under my passenger side of my Blazer.
I had the front end aligned. New shocks put on (they were needed anyways). I had the zirks all greased up. But the noise was still there. Every time I would go over a decent bump or pothole, I heard a clunk.
Many of you suggested it would be a suspension component. That checked out fine during the alignment. Some have suggested the sway bay bushings. Still fine there.
Well today I poured some SeaFoam down my TBI and when I went to put the TBI cover back on I noticed the mounting screw was loose on the TBI. This screw is what is used to secure the plastic housing to the TBI. So when I put the housing back on, I could easily move the housing that was supposed to be attached firmly to the TBI.
The simple fix was just tighten the bolt down a little more.
So far I have ZERO clunks going over things.
Just a thing to check ppl.
