Vehicle vibration (not sure if this is the right section to post in)
I have a 2002 2dr rear wheel drive Blazer that has had a vibration since purchase. I have replaced all tires, all rotors, all break pads, both front end shock absorbers, both front end lower ball joints, both front end upper control arms that included ball joints, both front end wheel bearings, both front end sway bar links, both rear sway bar links, both driveline u-joints, water pump, fuel filter and have done countless front end alignments and tire balancing. It still has a vibration after all of this work and I'm feeling at a loss for what's left I could possibly do or check. Please if anyone can help me I would really appreciate it. I love my Blazer and I don't want to have to give her up. The vibration noticeably starts around 65 and just gets worse as my speed increases. I have taken it to multiple mechanics and they can not isolate the issue as well.

My vibration diagnosis of unknown, unclear sources.
Preliminaries: Get a clear idea of what you are looking for.
You can do this also step by step if you can consistently reproduce the issue and drive there on a daily basis, this will facilitate your work. Or just go all-out and clean up, before starting do diagnose.
Have somebody with you - Either he/she drives and you listen and observe, or the other way round. One has his eyes on the road, the other diagnoses. 1st checking location and dependence.
Make videos and write down the exact parameters when it happens. Road, rpm, speed. Can it be reproduced consistently and every time even on a different stretch of highway? You should know a lot more about that vibration now then you knew before and it cost you nearly nothing except some time and fuel. Have I forgotten something or does anybody have better diagnostics? |
