    Hi
    As title says, I feel vibration, kind of side vibrations, when car is wobbling from side to side, during acceleration.
    Went to my mate garage, and has been told those are not drive shafts (as we thought before) but engine/transmission mount looks like needs replacing. Its lower torque rod Honda part PFKL647752. Could it be the real problem and would aftersale warranty cover it, or will they (Honda) treat it as wear and tear?

    Sev how many miles your 8th Generation done, I won't believe for one sec a engine mount has failed. Since you have confirmed the drive shafts are ok , It will be a more simpler like tyres , wheel balancing or even alignment.

    100% not wheels. It has 120k on the clock. You can feel the vibrations even when not moving, but much less than when driving. Since the gearbox is vibrating and the vibrations are transfered to shafts you can feel the wobling on the steering wheel but also the whole front of the car is shaking too.

    are the tyres wearing evenly? Jack the wheel up and rotate the tyres and feel the thread it should not have any uneven undulations.

    Engine mounts would be the most likely cause of vibrations. Wheels vibrate only during free way.constant speeds on 50+ all they need is balance. One of the mounts could be off do to wear and off set the engine. Just replace all of them

    If it's vibrating when stationary then the most obvious would be engine mounts. Worth having them checked one could have failed or come loose but I've not heard of it happening before.

    If not could a failing DMF cause such a vibration?

    Two if the engine mounts were worn out on my old car entire engine tiled about 1 inch to the left and vibrations were pretty bad. But mechanic assured me that mounts bot gonna fail completly so I drove like that for about 7 month like that. Lol

    Mate, that might be to expensive.
    Anyone know the proper way to test them?
    Waiting for info about parts availibility and repair costs. Should I try Honda warranty first?

    This was the first thing I was going to ask, is the repair going to be covered under warranty? Because if not, that could be expensive.

    Ok
    Had the car checked by Honda and have been told right drive shaft needs replacing. Full. Around £900. Warranty will not cover it because its wear and tear. Sick. Who should I belive now. Engine mount or drive shaft. £900 ? No way.

    get a second opinion before opening your wallet , why don't you take it down to Holdcroft Honda for their take on it.

    As Inchban said above get 2nd opinion could just need CV joints replacing mine were on advisory HH gave me was only about £300 did not have done at time now mine is vibrating badly at 58-63 mph it's not tyre's or balancing or like a lot of the scare mongers like to throw in DMF so will get round to replacing CV joints in next couple of wks as can't get upto the vibrating speed in York but like mentioned get 2nd opinion and if you can get to HH

    Have you fixed this problem?
    I recently bought a 2009 accord I-DTEC from a private seller with no waranty, noticed that the car vibrates from 100mph (the higher the speed the more it shakes), thought it was wheel balancing, wrong...:Blink:

    Today i got a new set of tyres in the front and balanced all 4 wheels and it got a little better but still vibrates and shakes a lot, now it starts at 110mph, i suspect there is something wrong with transmission or steering, anyone got this problem too? Help would be apretiated.

    The car is 100kmiles on the clock

    Quick fix... is it possible for you to drive at less than 110MPH? That might also bring other benefits! If you really must drive that fast, then you probably require specialist tyre balancing, undertaken with the wheels fitted to the vehicle.

    PS - 100kmiles, I think you mean.

    Can't work out how it's the driveshaft if it also vibrates when stationary, unless that needs doing as well.

    The car is 100k miles (sorry for the mistake:Blushing:)

    As i said before i already balanced all wheels, changed front tyres and it improved a little but didn´t solve the problem.
    The car doesn´t vibrate when stationary, would it vibrate if the driveshaft was faulty?? All gears change very well, its just on the highway i notice this.
    I usualy drive around 80/90 mph but i know there must be a problem with the car, thats why it vibrates around 110 mph, and i would love to have this problem solved to enjoy my first Honda as i deserve.

    Thanks for you advice Sayama but im from Portugal.

    Sev any updates on your car issue , unless members come back with solutions to what fixed theirs cars , we can go in a wild goose game of randomly selecting parts which could be the source .

    Hi
    Did you get your CV joints sorted? Did it help?
    I need to get it done before Christmas.
    The car has been one more time inspected by Honda and they said its a drive shaft, and the vibrations when stationary is a mount.
    So two different faults.
    I have got another opinion from Honda parts. They said they have previous experience with intermediate shaft bearing going bad, which too can cause bad vibrations.
    Anyone can confirm?
