Mk3GXL 9 Posted January 22, 2018 I think a one piece prop shaft will sort out the problem The prop shaft currently fitted to yours is, or should be, mint. It has a new rubber coupling, new centre mounting, new UJ's and was balanced but the vibration was still there. It comes through the centre mounting and, I now believe, is because of the angle of the 2 piece. One thing I was told and have done was to space the mounting out with washers and this did make a difference. I have a similar or worse problem with the GT so am thinking 1 single piece prop is the way forward with that car. Incidentally, both our cars have the original axles but neither have the pinion plates mentioned, don't know why but they don't which is a pain with my GT as I'm sure the pinion is at the wrong angle.

Paul B 22 Posted January 23, 2018 (edited) Quick question by a potential numpty... If a one-piece prop is best, why did they fit two-piecers? I'm not trying to be a smart a#se. Just wondering why. Edited January 23, 2018 by Paul B Quote Share this post Link to post Share on other sites

This issue was raised a year ago. I prefer 2 piece but was contrasted by many - had attached a technical report supporting my belief- will see what post it was.

Danish 294 Posted January 24, 2018 Quick question by a potential numpty...If a one-piece prop is best, why did they fit two-piecers? My guess is the Mk3 was designed to be a comfortable car not a sports car. I have a single piece prop, it gives a less woolly power delivery but is rougher and noisier - not really suitable for something for a travelling sales guy or Dad taking the family on holiday.

Pete-H 69 Posted January 24, 2018 Perfectly valid question, I've been wondering the same too, will be interesting to see what Pete comes back with. Not a Clue the Mk4 I had was fitted with a single prop shaft and if I had another one and it had a two piece I would change it for a single prop mainly as there are less things to go wrong.

Captain Scarlet 96 Posted January 25, 2018 There may well be a problem with the centre bearing on this car, but rubber couplings need to be parrallel with the back of the gearbox and the centre bearing ,they are not designed to flex in a direction like a UJ. Think about it,the original two piece prop on a mk3 had a UJ at the gearbox end . If the centre bearing is spaced down to line the rubber coupling up it upsests the angles to the rear of the prop assy causing worse vibrations. I hold my hands up and say i made the mistake of fitting a rubber coupling too,and tried to space and alter the centre bearing mount to no avail,and the new coupling eventualy ripped up. I think this has been discussed on this forum somewhere before. Quote Share this post Link to post Share on other sites
