If it's still the same (vibrating) it's one of these trans, driveline or rear end.. Really is not telling me much as I don't think it can be much more than that, aside maybe a wheel balance issue or front end.
What I was thinking was if it doesn't do the vibrating when the clutch is engaged at least I'll know it's not a trans problem or driveshaft etc...i know it's probably the tranny or driveline most probably.
I was just trying to see thru a process of eliminatio, I would be able to narrow it down batten those 3 main issues. That's all.
Thanks for your input as well, will see if I will get it done on the weekend.
Have a good day..
