    What are the symptoms of CVJs failing?

    My 90 Seville is handling kinda strange.
    1. On acceleration it waddles a little
    2. It wants to pull a little to the right.
    3. At low RPM and at 25 to 30 MPH, man the thing rocks like crazy. (engine mounts appear OK, movement under the hood is minimal).
    4. Slowing down to a stop I hear a growling sound.
    5. Acceleration, deceleration, acceleration, results with a clunking similar to a bad u-joint. (no noise)
    6. Parked you can rock the car a good foot or more with no effort.
    7. When turning or even veering a little to the right I can hear a light squeak.
    I replaced the front hub bearings and the tie rods, ball joints and brakes are good, as well as the CV boots.

    Any advice is welcome

    Swap the front tires with the rears and report back with results. I'm thinking a broken steel belt in one or more tires,

    ^ Good advice.

    If the boots are good on the CV joints, chances are they are perfectly fine. Generally, they'll far outlast the vehicle as long as the boots stay intact and the joints remain lubricated.

    FWIW Check the strut rod bushings, they are attached to the control arms toward the front of the car.

    Re: What are the symptoms of CVJs failing?

    Thanks Guys,
    Sorry I havn't gotten back sooner, got really sick, still weak from it.
    Hopefully I'll be able to get to the tire swapping later this week.
    What about the excessive movement when the car is in park? Item #6

    Try using the "PARKING BRAKE" . Its there to prevent excessive rolling once parked.

    Re: What are the symptoms of CVJs failing?

    Thanks carnut I appreciate your input, although it does not answer my question.
    Unless it is your expert opinion that much travel in the drive train is within normal factory tolerance. If not something must be out of whack wouldnt you agree. My other cars dont have that much travel.
    Use the parking brake? Come on! Isnt that like fixing a suspicious noise by simply turning up the radio? Although that technique works well with the squeaks and groans emanating from my vehicle. Still rides and steers like sh*!.
    Thanks Sevillian273. Strut rod bushings? Sound like helpful advice. Probability more likely than tire issues. This car has over 300,000 miles on it. I just dont want to rebuild the front suspension if the transmission is on its way. You know, money down the hole.
    Ill still swap the tires front to back.

    Over 300,000 miles, I'd say you have squeezed a good share of the miles out of that car. If the trans has never been out or replaced, consider yourself fortunate. Not too many make it that far. Growling sound, look at your rotors. You might not have a rotor seated against the hub. I'd jack it up with the wheels off the ground and trans in neutral. Rotate your wheels to check for wobble. You might even be able to hear that growling sound you are hearing when you step on the brakes.

    Re: What are the symptoms of CVJs failing?

    Thanks man. Id like to think it still has a lot of miles ahead of it.
    While Im swapping the tires Ill be looking very closely at all the components under there.
    Photos of the car are in my album, check it out.

    That thing is unbelievably perfect for it's age! How do you keep the rear end perched up like that after that many miles? All the ones I see around here are dragging ass!

    Thanks, I spend a lot of time at my local u-pull yard scouting for that car someone has thrown money at. I pull as much as I can afford and shelf the parts till I need them.
    If I find the right interior color, man Im on it. I found a mint, right color leather steering wheel for my 83 Eldo last time out.
    The stance is thanks to a pair of fairly new/used air shocks I scored at; well you know.
    Those spoke wheels; I pulled same place, $50 for all four with tires. They are TRU-SPOKEs. I do have a couple spots where the clear coat has issues along with some fading on the top side of the bumpers. The black trim moldings around the door glass has shrunk some too. The drivers door won't close tight either.
    Ive heard that about the Transmissions, but what I heard was, there are two models, early and late, one of which is the better. I cant remember which one through, except the one in my car is the better one. They use different pan/gasket shape.

    Gotta love those junkyards. I'm going to have to train myself to stop calling them junkyards...
    It gets addictive after going there a few times. I'm always on the lookout for a good part I might need in the future.

    Re: What are the symptoms of CVJs failing?

    Swapped the tires, man what a difference! Not pulling to the right and steers smoother. Thanks carnut. You are right, f%#*ed up tire. While the car was in the air I took a good look at everything, all looked tight and the brakes are at a good 90%.
    I couldnt feel any looseness in the bearings or CVs. The bushings looked OK, as well as the ball joints and tie rod ends.
    The front struts on the other hand are covered in oil, hmmm.

    You're welcome. As you know, replace that tire and ideally, replace both that were on the front.
