    Vibration under acceleration

    On my '07 DTS with 93k and I have changed the front motor mount and torque strut to no avail. From all the research I've done I'm expecting that I have a CV joint that is bad. Has anyone had this issue? How difficult is it to change the cv joint/axle shafts. They are reasonable in cost so I probably should change both sides. Thx.

    No certain speed. I can feel it during any level of acceleration. Of course, the heavier the acceleration, the more pronounced the shutter is. If I really baby it, it's not very noticeable. I can really feel it if I accelerate from 50 to 70 hard like when merging onto the interstate.

    Have you tried turning traction control off? I have some vibration on full throttle accel that goes away when traction control is disabled. Not sure why that would have an affect, but it does. Don't have the issue with moderate accel.

    Re: Vibration under acceleration

    Same thing with my GTP had to change CV joints and problem was solved. Most mechanics have a hard time pin pointing the CV joint, take a good one you trust on drive with you and show him.

    One other thing are the boots leaking any Green Grease. Mine never did so like I said it was hard to say CV joints for sure but it was.

    Good Afternoon peryan,

    I apologize that you are still experiencing this matter with your DTS after replacing the front motor mount and torque strut. I see that you have received some advice from our wonderful forum members and that you may be trying to take care of this on your own; however, if you decide that you would like to work with your local Cadillac dealership and would like us to assist with setting that up, please do not hesitate to reach out via private message.

    Sincerely,

    Jonathan A. (Assisting)

    Thx. Both inner and outer CV boots on both sides look new. No cuts and not leaking any grease. Also, I don't see any axial play on either side by trying to rotate the half shafts by hand while in park. I am really leaning towards the cv joints. Did your GTP have a shutter while under acceleration as well?

    Yes shutter on acceleration was the only sign I had.

    Before doing anything else I would go to a real good tire place, ( if you have not done so already ) and have them Road Force Balance you're tires. This is only $75 cost compared to $700-$900 for the CV Joints.

    Our DTS is very touchy about wheel balance and when you said 50-70 mph that is when balancing would show up. I had to get a good shop to do my Cadillac the Caddy dealer did not have the machine to RFB my DTS and vibration at 60 mph went away for me. GTP was CV JOINTS.

    Thx. I failed to include that I get the shutter at almost any speed but only while accelerating. From 50-70 mph is more of a vibration than a shutter and I'm sure the tires could use a balance as they have 35k on them. As the trans shifts into second gear, I can feel the shutter beginning. It appears only under load, then smooths out so that is why I am suspecting the cv joints.thanks in advance for the info.

    Re: Vibration under acceleration

    The advice about plugs and wires saved me a lot of money a couple of years ago. If you have a lot of miles on them I would go the cheap route first. If that doesn't fix it at least you don't have to do it later.
