    Having been looking forward to going up to Chipped UK for a run on the rollers - this weekend was a bit of a bummer.

    Faffed about doing what I needed to do on Saturday morning, got prepped and ready to head up to Bromsgrove.

    Got on the motorway, no problems. Pottered about normal motorway speed (70 obviously...:ninja:) up to the next services and pulled in for a slash and to have a ganders at the females that were likely to be wandering about.

    Left the services, pulled out into the inside lane and hit the loud pedal. Got to 65 mph and just changing into 3rd, the whole car begins to shake. And I mean SHAKE. Violently. Not good.

    Pulled onto the hard shoulder and took a look around the car to make sure a wheel wasn't about to fall off and it was genuinely that bad. Nothing untoward. Got back in the car, up to 65 - same thing.

    At which point I turned tail at the next junction and headed home. Arse.

    Anyway, had a good look around the wheel arches when I got home - nothing. Underneath revealed the problem.

    Rear end of the prop to the haldex coupling has 3 bolts. Mine had 2 and a bit bolts, and the 2 bolts in tact were extremely loose. So that at leas explains that.

    Was in a foul mood all day saturday and couldn't be bothered with the car. Went out yesterday and dropped the prop off - and getting this bit of snapped bolt out isn't going to be fun.

    It is completely flush with the face. :(

    Will take pics tonight just for reference.

    For anyone who is having unexplained shaking symptoms - check the bolts!

    Argh, nightmare.
    I hope that bolt comes out easier than you expect.

    That's a shame mate, at least you found the issue and it's not engine related! Good luck with the bolt. Sheared bolts are never fun to get out.

    Having spent 3 hours last night trying to get the bastard thing out - it doesn't want to.

    Two options left really.

    Weld something to it and try and wind it out, or drill it. Can also do both of those which is most likely, spot weld a bolt to it, try and unwind.

    Cheers dude. The annoying thing that it's completely my own fault. They obviously weren't done up tight enough when I replace the prop 6 months ago.

    I don't think I used LocTite either. I did at the other end - which is fine.

    if it makes you feel better i've had a wheel and caliper fall off over the many years. all my own fault. do not ever do wheel bolts finger tight with the intention of sorting later!!

    heat is your friend to get bolt out. welding will heat and give something to remove with. do not use easy outs. they snap and you will be drilling for a year!!!

    Used EZOuts in the past. And they are *****. I wouldn't even entertain the idea.... lol.

    OK if the hole is dead centre and 100% straight - which is never 99% of the time.

    Sorry to hear this mate, when I started reading and read 'violent shake' I thought "oh dear" but... I'm glad it's not as serious as first thought.

    A sheared off bolt though is no likey...

    I have bought stupid snapped stud removal equipment today...

    I couldn't find my set of HSS drill bits yesterday, and I still don't know where the are. I couldn't find my iccle chisel set either....

    So I just popped out and grabbed some supplies...

    If you can get heat into it spray some penetrating oil on it while hot and it should run around the threads like a rat up a drainpipe....

    Well, got the stud out. Bloody thing was a right pain in the chuff. Ended up drilling through the stud with a small bit, and hammering a torx bit in there. At that point it wound out easy as you like. Happy days. :)

    Got it mostly back together as well, just need to put the one remaining bolt into the prop....

    Well - annoyingly, changing the doughnut for a different one, and removing the snapped stud had cured the problem to a degree. However I now have an annoying vibration from something else, at lower speeds. lol.

    I can only now assume that it is in fact the prop as I have been back under to investigate twice - to no avail.

    Thinking I might just get a new S3 prop - mine is currently a TT front end, coupled with an S3 back end. I might just buy a second hand one and be done with it! lol

    Yes, as I found out.... the TT back end of the shaft is about 4-5" shorter than the S3 one. The TT is clearly a slightly shorter wheel base.

    How do you mean dude? damaged the shaft itself? It's not beyond the realms of possibility.

    However, when I got the prop bolted up with the two bolts (as the doughnut was so shafted I couldn't get the third in), it was fine lower speed, and then has a bit of a wobble at high speed as you'd expect.

    However, with the doughnut that fits and is the right shape, it's just generally unhappy...lol. Nothing else changed - so it's got to be related.

    I would have thought they were the same but according to Parkers TT wheelbase = 2429 S3 wheelbase = 2519 so the S3 is 90mm longer, learn something new everyday

    LOL tell me about it. That was exactly where I looked, and then decided they MUST be the same. Until I fitted it. You should have seen the look of confusion, and then disappointment when I was led underneath the car about to bolt the prop to the rear diff. The front was on and sorted, moved down on my creeper to the back, held the prop up and it was short.... Arse. The penny dropped.

    Hence why I have a half and half prop shaft!

    I've just ordered a prop off of a 38000 miler, complete, £150 delivered. I'd say that was a result.

    Yeah was thinking the flanges on the shaft, may have twisted slightly?
