I have an 06 with 109000 miles on it, bought it brand new and had the most amazing time with this dream machine. its my daily and my one and only car and I need some help figuring

out whats wrong her. Car is back to stock after being lowered on swift springs for about 5k miles with stock shocks. I get moderate vibration on slower bumps and rough roads and it

continues in higher speeds during regular driving acceleration, braking, turning etc. you get the point. i have hit the curb a couple of times on both sides of the car but fixed

the minor damage immediately. Currently running 215-255 combo tire. vibration started when i lowered the car and had non staggered RPF1. went back to stock and the shake is still

there... it could've been there before the swap but I honestly dont remember. The rear of the car seems to hop and its really harsh both front and rear are harsh but rear seems a

bit more harsh and bouncy. I have noticed the rear tire tread being weird to say the least on my brand new KDW's. I will post pic to show you guys what I mean.

I am taking my car in on Wednesday to see if this new mechanic I met can see whats up.





questions I have.

1) are my shocks dead?
2) is my rear end giving up?
3) is it my alignment? could bad alignment cause these types of issues?
4) would bushings and motor/tranny/diff mounts cause anything like this?
5) how do I know when to replace my mounts?

Thank you for reading up and please chime in with any advice or recommendations.

swap axle buckets?

alignment check might be needed...looks like the tire is feathering. must be good in the rain tho, big tread gaps

Does it only vibrate when accelarating?

Test it. See if the vibration goes away the instant you release the throttle.

If so, it's the axle buckets. you're at that mileage for sure.

Thank you guys for the replys,

The Vibration is at all speeds and at all times, accel decel on nuetral up hill down hill doesnt matter. its worse at slower speeds with kind of a bumpy read... except for smooth roads not as noticeable but its still kind of there.

I've gotten the tires rebalnced and checked the wheels for any imprefections. I checked suspension compounents for any loose bolts & nuts. and I also tightened down the front sbuframe bolts just to make sure because it was removed after a clutch job.. I will take it for an alignment since I have life time with Firestone.

any other thoughts? suggestions? the gap on the tire tread is odd...

double check rear tire balance or even better try another set of rear wheels.

Does it do it if you're coasting in neutral?

EssToOfouzEn

Yes it does

starchland

what happens when you apply some parking brake pressure coasting in neutral?

I havent tried that yet. hmmm.. interesting what would that prove?
