Engine mount shudder

Re: Engine mount shudder

Rang the dealer and told them I was concerned about the car being different to when I left it with them so they said bring it back and we'll do a test drive.

The bloke that came with me was very good. He said:

• it wasn't an unusual amount of vibration
  he has seen other D4Ds a lot worse
  he will log it and will appear against the vehicle for its lifetime
  he wants me to do a few more k's and report back (we are about to do 1700km this week)
  interesting part: the engine mount is electronically driven and kicks in when at idle to make it "feel" smoother
  this wasn't the first time he has heard post-10K vehicles exhibiting this behaviour
  he preferred the old TD to the new one - old one quieter, smoother etc.

Re: Engine mount shudder

Mines an 07 gxl..(27,000 Km) Mine shudders when reversing out of a drive way and has a vibration in the low rev area . It makes a droning noise into the cabin (between 1 and 2000 rpm.). Very annoying. Toyota say its the engine mounts and am now waiting for them to arrive. This is after a new tail shaft for the 'bump' (greasing didn't work)and new injectors etc for the rattle..Have had Toyota's before but never any problems.. Hope this spells the end of them after $60,000 for the car..By the way, apart from long highway runs and abit of beach sand work, this car has done nothing else.. Toyota tough??

Re: Engine mount shudder

Looks like I have joined the "shudderers" brigade. Moderate and unacceptable vibration at idle in Drive, easily fixed by slipping into Neutral when stationary. Engine mounts to be replaced under warranty and are on order from Toyota - mileage = 26,000kms. I hope that the injectors hold up OK and are not the next to go.

You know its interesting, if it was not for Pradopoint I would have accepted it as just diesel vibration. When I took it in for service, I was able to specify the symptoms and point directly to a cause "please check the engine mounts". That is another plus for this great online forum - well done everyone - keep the information flowing in.

Re: Engine mount shudder

we have a little amount of vibration which seems to come and go. The annoying part is the droning which i cant put my finger on yet.

Re: Engine mount shudder

Interesting comments.

I get a very noticeable 'thud' frequently when I move off from stopped, such as at the traffic lights. Doesn't happen all the time but certainly more does than doesn't.

As I have an auto (haven't had an automatic car for years) I just considered it life with an auto but maybe there's more to it.

About 6500ks now & will raise it as the 10k service unless it becomes a lot worse in the meantime.

Cheers

Re: Engine mount shudder

The thud you're experiencing is most likely the tail shaft. Toyota will probably grease it at the service. This should reduce the severity of the thud but probably won't solve it permanently.

Re: Engine mount shudder

Wow, what a feeling. :!: The engine mounts have been replaced and the whole car is soooo much smoother and quieter and not just at idle either. I guess there was vibration even at cruise speeds - makes me wonder how long these have been out of action. The Prado can now happily sit in D and no vibration thru to the cab at all. I just can't seem to break the habit of slipping into N every time I stop at the traffic lights I have been doing it for so long now. Oh, as a result of the vibration the fan shroud split and requires a replacement under warranty - . Never mind though it feels like a new car again.

Re: Engine mount shudder

The way the mounts work is that they have a diaphram inside that is operated by vacuum supplied through a vacuum switching valve & controlled by the engine ecu that looks at engine revs & road speed

When stationary & idling the diaphram is pulled back by vacuum & opens a passage in the mounts that allows the free flow of liquid (coolant) between 2 resivours within each mount to allow the mounts to be soft to absorb vibration but above idle the vacuum is stopped by a vacuum switching valve & the passage is closed to stiffen the mount to better control engine movement under load

Re: Engine mount shudder

it went in yesterday, ngot her back today,
"we have remapped your ECU and all is good now!"

"and when we started it cold there was no knock"

it didnt have a cold start knock i says,

"well we rung toyota, and they said it did(are they for real??????) so we did what they said and remapped the ecu"

did you drive the vechile at opperating temp i ask,

"our skilled technician tokk it around the block, and noticed no knock"

its intermitent i say, for the 8th time.

"ohh, ok well weve fixed the cold start knock(which it didn't have....) and if it does it again let us know and we will have replace injectors or mounts what ever toyota tells us to do."


man these people are thick, i originally spoke with the salesman who sold me the car, he said he would organise it, booking clerk rung me, i run through the problems with them, i ring service advisor and tell them the same, service advisor lets me speak with head technican and i explaint to him also!!!!!!


and i get my ecu remapped!!!!!!!!!!!!!!!!!!!!!! god i hope for there sake it has fixed the problem, cause i'm gunna blow up deluxe if it hasn't.


thats my whinge for the day :mrgreen:

service centre at this stage shall remain nameless..........................

Re: Engine mount shudder

Hmm, seems I have this shudder too. I opened this thread accidently but started reading anyway.

Occasionally, definitely not always, I pull up that the lights and its shaking all over the place. Slip into neutral and its fine. Probably happens at the the first set of lights for the day, but for me thats often 15kms of highway running from home. Probably only happened a handful of times in total, but I did notice it right at the start when the car had about 2000km on it.

Will ask Toyota about it next service, along with the dodgy bluetooth in the radio, a squeal under acceleration when cold and what I would consider, high fuel consumption (11 - 12 l/100km normal running) :roll:

Re: Engine mount shudder

Mine has been doing this from new & now done over 70,000k, been trying to get fixed & local dealer service dept wont replace mounts until they "diagnose the problem" which they havent been able to do yet as being intermittent it hasnt shown up when they have tested and dont seem inclined to believe what I tell them. Has also cut out 3 times with no codes shown even though engine light comes on, idles very rough when cold, fuel consumption has increased by approx 10% since new & has had turbo replaced under warranty. Recently had ecu upgrade which quietened cold rattle by around 50% but still noisy, permanent solution may be to buy another make of vehicle.

Hi, is anyone else experiencing a problem with a severe intermittent shudder whilst the vehicle is in gear at idle and under brakes (at traffic lights for eg)?
I first experienced it 4 months ago and Toyota replaced the engine mounts which fixed the problem, but it has now come back. Toyota tell me that mine is the only case of this that they are aware of - I would like to know if anyone else has had or is having this problem and if Toyota (or anyone else for that matter) has provided a permanent solution?

Mine does this and it seems to have become worse with age. I did not notice it till about the 20,000 km mark.

I have not raised the issue with Toyota yet but I will when I get down to Adelaide again.

Re: Engine mount shudder

I had the shudder on my vehicle took to local Toyota dealer mentioned the problem ,they couldnt find it so rang Toyota Tech Support were told to replace the RH engine mount problem fixed in one afternoon.
Cant understand how one dealer gets one bit of advice and another gets different advice,either I lucked out and got the right person at Tech Support or some dealers just cant be bothered,

Re: Engine mount shudder

Just had a service, and asked dealer to check out shudder. He said in the end that he would not replace the mounts because Toyota has ordered that ecu be remapped first. So I hope this works. Probably won't know untill next winter as it doesn't do it until ambient temp is low.

I just can't believe from reading the posts above that engine mounts could be so complicated. This really is a case of trying to be too clever, adding unnecessary complexity which in the end is just more to go wrong. I'm sure Range Rover owners would know the feeling. Whatever happened to the KISS principle. I can't even work the DVD recorder without 8 hrs of study ops:

While I was discussing issues with dealer , found out there is now a special way to check engine oil. Can't check when cold he says or it reads too high. Must check when at operating temperature after stopped for a few minutes. Sure enough it says this in the handbook. (who reads how to check oil???) :?

Re: Engine mount shudder

mines back in get looked at again. been there a day now and they can't find the fault. apparently there engine mounts checks have shown nothing, no fault codes, ecu is all good. service advisor told me just to put up with it!!! ahh he was wrong!!!!!!!

told them to keep the car there until the have fixed it, i got another 120 to drive around in so i dont really care how long it takes! if it wasn't for the help i'm receiving from the salesman who sold me the vechile, i would have tapped a chin by now.


anyone found a soloution to this rattle yet?


cheers
