Vibration

[RICHEYSGTP]

I've got 04 gp and anytime I'm on the gas or with cruise set I get a vibration as soon as I let off the gas it stops
I don't really feel it in the steering wheel just in floor board and seat
Car has new brakes rotors calipers tires and alignment. Don't just wanna throw parts at it

Its probably going to be one of the CV axles. I would check motor/trans mounts too.

Thanks I'm hopeful it just a cv axle or tie rod and I'll have the mounts all checked also. There's 3 of them?

 

[Sushamouf]

There are four. One engine mount, one trans mount, and the two dog bones. The problem child is usually the engine mount because its hydraulic and usually fails.

Ok I've got underneath. The trans mount is dry and looks clean
The lower engine mount has oil/ grease on top of it and all over front of oil pan
Is this what they do when they go bad?

They leak, but your oil pan gasket leaking is probably what you are seeing.

Ok think I got it figured out the vibration got hella bad when accelerating and cornering right at higher speeds I bought new cv axles and tie rod ends
Hopefully the repair goes smooth I've never done cv axles

Make sure you get an alignment when you're done if you are doing the tie rod ends.

Ya I will next weekend I just painted the old tie rod and threads so I'd know where to tighten it to

I'm going to disagree based on personal experience, though I can't say for sure if that's where the rumble comes from. Besides, you'll need a solid rubber lower engine mount to replace that fluid filled one sooner or later... it's cheap, it's easy.
