rent I've had the following give me some shake/vibration :

Balance
Tire
Bent Rim
Blown CV joint
Worn Tie Rods

Anything with the tires is easy to check, just do a rotation and inspect both tire and rim closely. I've found missing weights before, frustrating but easily fixed.

2 or my stock rims have bends in them. They're not bad, but they produce a slight vibration at speed. I know about it and always keep it in mind. What I found extremely interesting was that changing out the front tie rods from stock to Moog parts and making sure they're greased took away some vibration and slop out of my front end.

I killed my passenger side CV before I was out of warranty, but I was on a trip from Vegas to 29 Palms when it happened. The vibration was more fairly significant, luckily it held together until I got a dealer to look at it and eventually warranty it. I had to do my drivers side axle last year, but it was still in pretty good shape when I saw the boot had torn. You typically can hear them, but they're easy to check.

Has anyone mentioned wheel hubs? I haven't had to replace any of mine, but some folks have gone through them like candy. My car is also extremely sensitive to how much torque is applied to the lugs, the last time I had tires put on, the guys used pneumatics on her and I had to undo/redo all my lugs as it produced a horrible wubwubwub sound at 50 mph or greater.

rjschi21 With the shaking on acceleration I would possibly believe an axle could be bad.

NyBunny585 I had a rear suspension issue mine still does a "booty shake" but my rear suspension is off from a deer hitting me. I need the rear driver dog bone mount from ford to correct some ps the issue. The suspension is very picky! Especially the rear on the SVT, upgrades are definitely looking like the best best at least for me!!!!

apagios a Roadforce balance will tell you if you have a bent wheel too.

I had a wheel on the Miata get bent such that the face of the wheel was no longer parallel with the flat part of the wheel that mounts to the hub. Basically it looked round to the naked eye, but threw up like 50 lbs of road force! A rim shop was able to pull it straight/true for me, now only reads a 4 lb road force.

SD_Rider Just recently happened to me on my Pathfinder. The days of the stick-on wheel weights...

bluedevil03 You would be surprised how many ppl throw weights after they get new tires or the tires have excessive road force and have to be rebalanced.

tukaniSVT ^^ That's a good suggestion.

If it only happened on a trip, it could just be the balance is thrown off again.

If you had a motor mount issue, it would do more than vibrate it would also make a metal to metal sound of the engine bouncing on the mount with a bad rubber.

bluedevil03 Sounds like you threw a wheel weight to me. Have them rebalanced using a roadforce tire balancer if it still does at higher speeds like then then maybe a motor mount.

tnealley Thats what im thinking i have also.. guess its time to jack her up...

Joni4TA I had both issues. I replaced my tires first cuz I could visibly see they needed it, and the problem went away. Then it sort of started up again... while repairing an exhaust weld I noticed I also have a broken motor mount. Hopefully that'll fix me up. I ordered a new (better than stock) one from newedgeperformance.com
