I purchased a 97 Olds 88 a few months ago.
super nice, one owner, Florida car, had 41798 miles on it.

Owner could no longer drive

New tires, Michelins were installed and drove it home.

I notice it feels like one of the tires are not balanced and it is shaking the car at speeds 60-65 and up

I then have tires rebalanced.... and still getting what feels like balance shake

I take it to a road force balance shop, and sure enough, one tire had 18 lbs of road force, they demount tire and turn it on the rim, rebalance, now ok

drive home and still have harsh vibration above 60-65 and up

replaced all struts and did alignment, both front axle shafts (two times), rotors
problem gone? NO

car runs and shifts perfectly, just this harsh shaking

had yet another road force balance at another place, inspected tires, wheels, hubs....all perfect

dozens of no results shops later, I still have the shakes

seems nobody can pin point what or where the shake is coming from


tire places say the tires are not out of round or wobbles of any kind

alignment guys inspected everything, can't find anything

they all drive it, feel the vibration and shrug their shoulders and puzzled, ask for payment and basically tell you to leave....

I took a jack and raised tire from ground, inspected ball joints, using pry bar under tire, did find pass side rear have play up and down...in ball joint and replaced it

all others were fine
hubs are quiet when rolling, and no resistance
all a-arm bushings look fine,,
with jack under front arm, tire off ground, started up car, in drive, let wheel spin, tc off I do notice a shake on drivers side, removed wheel, checked again
I put all the lug nuts back on to hold rotor, and spin again
the car vibrates like the shake when driving 65 and up

I notice that the AXLE shaft is vibrating, and has a slight wobble to it, the outer cv joint near tire vibrates extreme enough to make the rubber boot hit the bottom of the strut, yes, the wheel is turning fast... prob above 100

could this be my shaker?

One of the mechanics had already replaced my axles, a month later, another says that it looks like I have a bad axle on drivers side, explained, it is only a month old, showed me the wobble so I replace it again.. this one wobbles too

The car had never been wrecked, runs and shifts perfectly just this damn shake while driving 65 and up

I do hear "POPPING" noise from rear of car once in a while, I am assuming its from the rear brakes (drums), they are new too.. as are the front rotors/brakes

Motor does not move much when checking mounts, place in drive and set the brake, gas it to see if a mount is bad, everything appears to be perfect

anyone have an idea where my shake is coming from?

I just replaced the drivers side axle shaft, 3-20-2013 .. makes the 4th shaft .. and yet it seems to shake the same


also note, rotated tires, shakes the same...

I have been on many forums, seems a lot of people have the same issue, but no fix for this vibration

can anyone help?

attached are a few videos of the shaft that was replaced

while having the shaft pulled out of transmission, I did try to wobble the output shaft, it's fine
