    Propshaft Vibration

    Hi, I had a slight vibration from propshaft at 50 mph, I sent propshaft off to Driveline in Morecambe uk, to be balanced, the have added a weight to the front half of prop near centre bearing, but now it has a very bad vibration from 45mph, has anyone else had a prop balanced & if so, did it solve the problem. Going to try a second hand prop & see how that goes.

    I have heard of jaguar doing something with balancing nuts, maybe main stealer only for that though.

    Many thanks,

    Chris

    There is a feature on the SDD for the drive shaft balancing in the diagnostics tools. You may have this done by a stealer or a good independent.

    Chris I've been misled before long ago by an unbalanced rear tyre which had a bubble on it on the inside, due to a daft tyre fitter who hadn't checked it properly but assured me they were all ok.

    So... Get your wheels balanced.

    A soft shock absorber will transfer the oscillation into vibrations similar to prop shaft.

    If it's not a tyre then mark the shaft so you don't lose track of where it was, and try turning the shaft to the next bolt hole at the diff, and again if you need to.

    Hopefully it will reduce or eliminate the vibration, but they normally only vibrate when the universal joints are worn.

    What was the cost of balancing?

    £60 to balance, I have checked wheel balance, it is definitely the propshaft, it only had a very slight vibration, after balance it was really bad, i have a donor car & swapped prop today & all seems ok now.

    I have a very slight vibration at the mo, brand new tyres fitted, and it was there before i had the tyres done, I have however, spotted that the nearside driveshaft isn't fixed into the diff properly, as in I can move the whole universal joint up and down by a good half inch, still can't figure out why it hasn't exploded yet, so it's getting the gearbox replaced this weekend. Can't risk the aftermath while towing my caravan or worse still, 2 race bikes.

    It's possibly the universal joint.

    But I forgot to.mention that they also have rubber "doughnut" flexible couplers which perish. Those are the most likely.cause.

    That's a good price Chris.

    If the propshaft has been off the car it MUST be put back on in the same position, same bolts, same holes. A dab of Tipex on the mating flanges ensure it goes back in the same place.
    That's what I was always told when I did a bit of spannering for a living.
