08 PPV 2WD CHASSIS VIBRATION

[04BUCKET]

New to me PPV with 165k...runs great other than a vibration noticeable at speeds above 70...not so much in steering wheel, heard a little clunk with gear engagement so I had ujoints replaced but vibration remains.

Tires maybe? Tracks on the road pretty straight and tires don't make a lot of noise...had them balenced as well just a couple weeks ago.

Anybody else experience this in their PPV?

Maybe a wheel weight fell off. I would rebalance

Going to do that anyway...just doesn't feel like a wheel issue. I know there is a pinion whine I want to fix shortly, just wondered if it could be something common I missed.

wheel weights will be easiest start point (find place to do road force balance)
then look into high speed balance driveshaft

if you have pinion whine, there could be something w/ that too.

is it stock height? lowered?

Going to do wheel balance this week.

Not sure who to even ask for balancing of driveshaft?...ideas anyone?...

The pinion whine is very minimal.

Its a lowered PPV vehicle with all original parts. Handles great and smooth up to about 70mph..

Ever find out where the vibration was coming from? I have an 2011 ppv and there's vibration coming from the rear at slow speeds. Any suggestions?

Your problem might be the AFM/DOD switching from V4 to V8 mode when slowing down. That was my issue. Disabled the AFM/DOD with a DiabloSport Tuner and fixed the issue
