I have the same thing Pathman. '03 pathfinder SE, 85K. New u joints, front and rear shafts. I had a thread on this before with no concrete solutions found. I don't like it either, but throwing parts at something like this can get expensive.

in these kind of problems you have to proceed by elimination or else you'll spend alot of money... To see if it has anything to do with your front drivetrain do these steps one at a time and test before doing the next one:

1) remove the front driveshaft
2) remove left half-shaft
3) remove right half-shaft
if it stays the same, then check if you do not have an engine or trasnmission mount that is broken.

Is the vibration getting worse with speed or engine revs ? does it calm down between such and such mph ?

all 3 tests can easily be done in an afternoon.

If the problem persist , it could be as simple as the rear ujoints. You can remove the rear driveshaft and see if the ujoint moves freely or has any play in it... You don't need alot to create a vibration...

Hope this help a bit.

i had this same middle viabration problem at around 90k miles, one of the weights on your rear driveshaft most likely fell off, check it, there should be 2, if not go get it balanced.

thanks all good tips have to get the rear drive shaft balanced and new u joints also need to re check the motor and trans mounts i will let yyou know what worked,

mechanic is wooried about "excessive play from the frt drive shaft into the transfercase.... should i be worried?

lol if your worried bout the front drive shaft, quick temporary fix= warn hubs even without the problem, you should think bout it.

appears to be some play in front drive shaft into transfer case but no fluid leaks rear drive shaft and new U jpoints done 60 % less harmonic buzz vibration under driver seat. mechanic wants to find a used tranfer case to replace but I think i am going to enjoy the vibration and keep the fingers crossed............
