Engine Vibration Help??

zephyrsn95 · Nov 26, 2006

:help2: Heres my issue. above 2000 rpm a vibration accurs and gets worse the higher you rev.
It starts off smallish to very very annoying.

Im trying to find out any ideas what to look for so
heres what ive done to narrow it down and faqs

Stock 95 5.0 with 150000 miles on it.
Billet Flywheel
Centerforce stage one clutch.
Harmonic balencer 8-10 months old (stock) napa part
Solid Full MSD Ignition
Mcleod Bell (yes it was dial indected)
TKO trans
FMS Driveshaft (with steeda spacer)

Vibrates most noticeably at 4000-4500 or so.
No difference whether in gear or neutral, or clutch in or out.
Speed makes no difference.
Motor very healthy as far as gas milage and power and how it runs.
Synthetic Oil with no leaks
This issue has been progressively been getting worse for the last month or so, Im afraid im mess up the motor if i dont fix it.

Thanks,

Toby

Check that balancer to make sure it hasn't walked out.

Balancer Balancer Balancer. Even if its only 10 months old, the stockers and stock replacements SUCK. get a romac or something similar and never worry again.

Replace those old U-joints in the drive shaft. I just did mine last week and it drives smooth as silk..We sometime overlook the parts we all beat to death. the u-joints usually cost around 12-15 bucks each and theres only 2 of them. DO NOT buy the ones from Advance auto. Get the ones from A smyth or somewhere like that. Just a heads up

the drive shaft is fine, i recently converted to a tko with fms driveshaft. For temporary i took one of my spare ford balencers and replace the crappy napa one that was on there and its alot better now, not perfect but much better.
