What I did so far:
Balanced crankshaft (no vibrations in park - engine running smooth).
This made things a lot better ;)
But still vibrations while driving over 60.​
Suspension (except leaf springs and high jackers) done.
New rear end (before 7 1/4, now 8 3/4 e-body rear).
Balanced driveshaft.
Aligned my 904 tranny.
No improvement.​
New Toyo tires (instead of BF)
This was a slightly improvement but no game changer.​
Symptoms:
Over 60 mph.
Sounds like: VROOM VROOM VROOM.
The faster you go the more intense it becomes (not faster).
Comes through the floor and the seats vibrate like massage seats.
What I am going to do next:
My tranny loses some oil, so this will be the next thing to look at closely.
I’ll keep you updated.
If somebody had tranny vibrations and fixed it, let me know...
