       vibrations

       Evening fellas,
       my S3 has developed a vibration that starts at around 35MPH, but
       then stops again at around 45MPH.
       it only does it while accelerating...
       I have checked all the UJs on the props, 1 had a 'little' play
       but nothing that I would call excessive lol, but I replaced it
       anyway... still vibrates
       the wheels have been balanced fairly recently so im ruling that
       out...
       the fact it stops at 45mph just confuses me???
       I have been told to check the swivels, which I will do tomorrow
       but Is there anything else to check??
       thanks guys and girls
       Dean

       How are your tyres?

       old...
       the problem came on very quickly so never concidered the
       tyres... surly tyres would get worse over time??

       I also get vibrations, not nice at 70mph, I think it's my
       Security x-plies, I'm sure they're not rated for much over
       50mph.  :eek:
       Can you borrow another set of tyres, & see if it makes a
       difference?

       If the carcass is deforming when driving you could get this - it
       may have been getting worse gradually but you might not have
       noticed anything* - try raising and then lowering your tyre
       pressure by 5psi (say) [providing you are running safe
       pressures] and see if it makes any difference.  We had old tyres
       on our skoda and we had a lot of noise/vibration (thought it was
       a wheel bearing to start with) problem solved with new boots!
       Anyone with more experience?
       *The nature of a land rover means that you may not have noticed
       any slight extra noise/vibration. Also your tyre pressures may
       have changed making the issue worse or you may have damaged a
       tyre without being aware of it.

       Kev, as you increase your speed, the heat generated will
       increase - the maximum speed rating on your tyres will have a
       margin of error but I wouldn't like to be doing motorway speeds
       on a 50mph rated tyre  :o

       Sounds like wheel balance, have you lost a weight off one of the
       wheels?

       wheel balancing is not really needed until you get over about
       50. I have none of my balanced since it is not really necessary

       If you can safely get all four wheels off the ground, run it
       slow in a low gear and look for 'run out' on the tyres and/or
       rims.  In 2wd you can do the back wheels one at a time but to to
       do the fronts like that you'd have to temporarily remove the
       rear prop. Sorry-don't mean to state the bleeding obvious!

       Necessary or not, im having them balanced in half hour as i
       checked the wheels and found about an 8inch clean spot on my rim
       where, i presume, there used to be weights 8-)
       Its just not something i concidered as they were only recently
       done...
       Cheers for the heads up and i'll let you know this evening
