    Default Scenic wobble

    Our 2003 scenic has developed a wobble under acceleration and load between 60 and 80 ks

    The car has new rims and tyres on front end and ive replaced both top engine mounts

    Before I start pulling it down any ideas on what I should look at first

    I suspected as much looks like the wreck in the back yard is going to save the day yet again.
    Axle transplant coming up.

    Should I be getting any noises associated with the wobble and if one side is on the way should I expect the same for the other

    To check this out, jack up each wheel and place in gear and see what wobbles at the speed.
    Warning high risk activity

    Therefore….. make certain you video the accident for our amusement.

    Is it a manual or an auto?

    The car is a manual transmission
    Driven Mself harm abilities are high enough without high risk activity. I once tried the jack up and watch on a R12 when I was a much younger fellow. The car needed a new bumper afterwards and yours sincerely had gravel rash on the elbows

    Seriously though in all my years of fwd cars Ive never experienced this wobble even with worn shafts

    Check the strut top mounts too.
    These wear and can cause wobble under acceleration.
    But if it is a worn strut mount you should hear some knocking on rough or corrugated surfaces though, at any speed.

    Cheers

    Hi Don,
    If you would like a second opinion then I could have a look with you, PM me if you want.

    I'm thinking shafts like the others but while it's jacked up have a look at the lower control arm inner bushes too.

    you said new tyres, is it possible they are delaminating internally, or was the problem there before you changed them?? As a young fella i was lucky enough to get talked into a set of Bob Jane All -Rounders (since found out they were known within the trade as "outta-rounders!) and they used to nearly shake my 2.4 R30 Skyline off the road between 80 and 120....
    If you know someone with a wombat (Scenic) that is near you it could be worth trying to swap over the front wheels and see......

    Just swapping front to back should answer that question. I also fixed vibrations just swapping new tires left to right.

    hi guys

    the problem has only started in the last month or so

    In the last 6 months Ive done new break pads and new front rims and Hankook tyres.

    Jaahn if your home on Monday or Tuesday Ill bring the car over to waratah for your deliberation.

    Im thinking just to replace everything on each side as the wreck in the back yard has only done 140K and was a very nice tight drive..

    I literally LOL'd at that!

    I've done the same with an R12 on stands, but without the accident.

    Some very good advice here. Cam740 has a very good experience that should be checked first perhaps before taking more expensive and difficult things apart.

    My contribution: don't overlook wheel bearings. If on the way out, they can be a right bastard. Check by slowly rotating by hand the suspected side (wheel off) and listen through a tube or something, directly on the hub (perhaps take the calliper off - but keep in mind to check calliper/disc for clearance and out of round).

    One suggestion for on-jack stands experiments like the one suggested in previous posts, just take the wheels off. That will significantly diminish the rotating mass and go a long way towards preventing undesirable, youtube worthy events. Of course, it will minimise vibrations, but if the vibration is to do with rotating transmission organs, you'll still see it there. If everything is peachy keen, I'd say it's the wheels and you can follow this experiment with some of the suggestions above.

    If you do suspend the front end do jack the lower control arm up so it works at working road height.
    Doing each side can be helpful in finding problems.

    Got home from my 5 day work stint and took the scenic for a test drive.
    Replacing the engine mounts has had a totaly satisfying result as far as the smoothness of the engine vibrations is concerned
    We now have a definate clunk associated with the wobble that is obviously drive shaft wear oriented. The hub bearings seem ok and we need new discs on the front so ill transplant the units off the wreck residing on the lawn in the back yard

    Ok so the right hand shaft had an intermediate inner boot replacement last year.
    looks like the yoke clip has detached and the grease has spun out hence the wear wobble and clunk.
    replaced shaft hub and disc as a whole unit
    these are bloody heavy if you are a one man band.
    also replaced the suspention struts on both sides of the car.
    there is a little play on the left hub so next week its the left hand sides turn for a transplant

    The wreck in the back yard has saved me $$$$$$$$$$$$
    problem is its so smooth on the road i can now hear the rear bearings sounding their discontent

    With drive shafts to rebuild and a gearbox removal for the proffi 25 it seems my next few weekends are gonna be very renault oriented
