Driveline Vibrations After RXT Install

[cdmustang2016]

I had Mcleod RXT installed. Since installed, you can physically feel driveline vibration throughout the car. From 4k to 6k medium to WOT acceleration you FEEL it. In higher rpms vibration feel is less.

Also, in any gear around 2100 rpm....there is humming/vibration you can hear and feel

Also, feel the vibrations during deceleration as well

Anyone else experience this?

I have Roush SC, 79mm pulley, ID1000, 67MM TBD, Lund tune.

Alot of guys forget to mark their driveshafts before they remove them and then put it back in a different alignment therefore vibrations are present! Reclock your drive shaft till you find its original position!

So let's say you're installing a different complete pumpkin...do you just guess and go trial by error?

You mark the ds to the tranny you connect to the new pumkin if you have vibes you didnt have before then you reclock the pumpkin end to the position it likes. When my dynotech ds was installed during my na build i drove the car home from and it vibrated like crazy. i reclocked it and it smoothed out! Driveshafts like 1 position and you gotta clock it to get it there. Sometimes you get lucky but when you don't this is what you do!

Driveshaft was reclocked correctly. Mcleod is saying I need have the clutch/flywheel balanced as a full assembly. Say this is not common but occurs when stacking components
