      I have a 2oo1 b5.5 passat sedan i recently picked up for cheap. The car was on cut springs and blown struts. I just installed JOM blue Line coilovers on it to solve the suspension problem. While i was doing this i realized both the cv boots were torn and needed replacing. I replaced the axles. The passat is a 1.8t with tip tronic trans. After i did the axles when i put the car in drive and let it idle i get a fairly noticeable vibration through out the car. It does not happen while driving or while in neutral. This did not happen before i did the axles. It doesnt make much sense to me? Any thoughts?

      I assume aftermarket axles? Fairly common to get vibration in these cars if you use aftermarket axles. The originals are hollow and vibration tuned, the aftermarket ones are solid steel sticks. It seems paradoxic that the vibration could occur at idle, but enough people have reported it that I have no doubts.

      Pull them and get new or rebuilt VW originals.

      Put in a GSP Axle (aftermarket) and it vibrated horribly for 2 weeks, until it blew apart just casually driving through an intersection.

      Thanks guys. This is what i feared. I will have to pull them and grab some stock oem axles. Should have done this from the start.

      Yes, everyone. Probably better than new VW axles. Buy them.

      why would you get vibrations at idle because of the axle? and not while driving which is what he's saying unless i'm reading it wrong?

      Good call there is no reason why the axles would cause vibration if the car isn't even moving, I'm willing to bet that the axles aren't the problem.

      seems like a bad mount. maybe you notice it more because the suspension is stiffer now.

      I agree that it doesn't seem to make sense, However, as stated above, MANY people here and on other forums report that bad axles caused vibration, even at idle. I'm inclined to believe it.

      I guess it could have to do with the car being in park but I still doubt that an axle would cause a vibration at idle and not in drive or neutral or when driving but I guess anythings possible. I'll stick with my manual tranny

      start planning on getting the engine mounts (2), transmission mounts (2) and snub mount (1) replaced soon. sounds like you've got several issues going on at the same time. the old suspension was probably hiding a lot of the vibrations that you are now feeling. raxles will help, but if you're still getting too much vibrations at idle, i'd supect the various engine mounts.

      a good test is to pop the hood and have someone sit in the car while it's running. watch the engine for too much movement while changing gears. put it in drive, and with your foot on the brakes, give it a little bit of gas to put the engine under load. excessive bouncing or movement will indicate bad mounts.

      the mounts aren't too expensive but the labor isn't the most fun job as it requires the engine to be jacked up a bit in order to relieve the pressure of the engine sitting on them. the snub requires the front to be put into service position. some have been able to do the snub without this, but it's much easier to work within the small space where the snub is if you at least loosen and move the front bumper and radiator supports back a bit.

      Ok so i replaced the ****ty auto zone axles with OEM volkswagen Passat axles. The vibration is gone completely. I guess i learned my lesson on taking the cheap way out. Dont do it. I also think it is time for new motor mounts as well. This car was pretty abused by the PO and i have spent the majority of the time ive owned it making it right. Anyway glad the P is happy again. Thanks for all your feed back.
