bad vibrations

[5.0fox]

im getting a really bad vibration at about 60 mph i had all 4 tires blanced checked my motor mounts and made sure my drivline was still balanced. what else could it be. it does it not matter what gear your in and it still does it with the clutch in. im stumped on this one guys plz help.

thx in advance

if it does it in any gear, does it also do it in neutral? dont forget the harmonic balancer.

good luck.

Sounds like the driveshaft to me... Had the same problem, new shaft solved it..

u-joints maybe?

 

[5.0fox]

it does it in neutral the u-joints are still very tight

what could cause the driveline to do this?
i looked at it and cant see anywhere that the weights came off

 

[HISSIN50]

if it does it in neutral (and stationary), it is not the DS. i stand by my first post as something to check.

good luck.

make sure your h pipe and catback arent rattling against the tranny cross member, or the gas tank, and the park under your car where the trunk would be

its not the balancer because it only does it when you get up to 60 mph it has nothing to do with the rpm i can turn the ignition off and it will still do it.
could it be the balljoints?

im stumped guys help

just to clear this up i think some of you are thinking i meant stopped in neutral but i meant get up to 60 then slide it into neutral

You've had your driveshaft checked by a driveline shop? I read your first post and wasn't clear on that.....If not you may want to do so. Also if you haven't had it out and back in recently you may want to make sure you ds bolts aren't loose
