vibration through drivetrain

[shaggy]

i have a c220 diesel esprit 1995 202 when im driving i get vibration through the drivetrain and when the box (its auto) changes gear it shakes even more when in the lower part of the rev band (at the begining of the gear) it is at its worst when i drive while turning the car e.g. when i turn into a road etc and then accellerate while the car is turning
ive changed both engine mountings
it seems to be getting worse :-( or im noticing it more anyway
any ideas as to what it may be
i find the engine a bit numb and am getting 32 mpg if that helps
thanx in advance folks

Sounds like one or more of the driveshaft/s constant-velocity joints are 'shot' (There's one on each end of both driveshafts).

Well within the scope of an independent garage/mechanic, but shop around for price of the joint/s. They're fairly complex therefore pricey. Main dealer most likely to offer you complete replacement shaft/s.

Also check the propshaft bush'es. I had very simaler symptoms to yours. It turned out to be the rear prop bush, it was almost in peices.

What milage was the car on when that happened Stwat?

i presume the prop bush's are whats commonly known as a 'donut'?
my mate recons they are prone to going?!?!
driveshaft c/vs are these available as a c/v joint or is it going to be a full driveshaft ? ive had this before on a front wheel drive car and it was cheeper to buy the whole shaft than put a joint on :-|

 

[tom7035]

Yes, the propshaft universal joints are known as 'donuts' because of the way they are constructed. As 'stwat' suggests this is another possibility (and much cheaper to rectify!).
It was the 'cornering' angle on things which led me to think of CV joints, but, on reflection, it may simply be due to the slower speed and more torque which would accentuate the symptoms from a knackered propshaft coupling.
Its just like a big rubber donut with bushed bolt holes. I hope this is the case, much easier as I said.
Good luck.

CHEERS
i searched last night and found a company near me that recon or repair c v joints so will call them if the 'donut' dont work

 

[shaggy]

just called nigel thompson transmision shafts in leeds & they say you cant get the c v joints seperatly so they would have to recon the shafts and all 4 joints (2 on each shaft) at a cost of £125 + vat per shaft
is this cheap ?

 

[shaggy]

O M G :sad:
the driveshafts from merc are over £600 + vat EACH
so my question is answered
fcuk me :x £125 each dont seem so bad now

So where do they get joints to do the job? They don't MAKE them. They should be available from alternative manufacturers, not MB. However, having said that, their recon. price does seem extremely reasonable and I personally would have no complaints at that. Have you checked your propshaft 'donuts' yet though? Could still be the cause.

Cheers.

checked the donuts and the c v joints all seem fine with NO play in them but the mechanic tells me there is slight play in some of the rear bushes so thats where we are going to start :roll:
he said wait till it gets worse then we will know exactly where the problem is

It was at about 119.000 miles. One of the previous owners pulled a masive caravan around( i found a pic of my car next to said caravan in the boot when cleaning the car) so i think thats what did the damage.

this just gets better NOT
my mate had a go in mine and recons my engine is a bit dead
had it to a specialist and his computer wont connect to my ecu
asked him about the vibration and he recons its the gearbox mounting
the vibration is getting worse though
he says the dead engine could be an airflow valve thats situated on the rubber air pipe between the air filter box & the inlet manifold
he says the only way to know is take it to a main stealer for faults to be diagnosed etc
so thats where i am at the minute
just a note though when im doing 95 ish it belshes black smoke
so its to the stealership for a reading i think :-(

Keep us up to date shaggy please, as you progress.

im booked in at the mb stealership in york on wednesday at 5.30 so will get their mechanic to check the donuts etc after he has read the computer for the fault on the airflow etc

Good luck and cheque book at the ready mate...

*UPDATE*
went to stealership and got computer read faults as follows :-

005 crankshaft position sensor L5/6
008 fuel metering control fault in operation
010 intake pressure control or not fitted
011 start of delivery control
019 road speed signal ABS N30 or not fitted
021 switchover v. ARF Y27 voltage tml 87 or not fitted
024 switchover v. Y3/4 , Y3/5 or not fitted

they recon these faults are old faults and nothing to worry about they cleared all the faults and retested and no new faults came up
they said come back after a week or so and they will test again
faults 005, 008, 011, would cause the car NOT to start so they say have my injectors tested and the pump timeing just to make sure its all fine,after that its the pump
as for the shakeing he says its the gearbox mounting so will have to check this out

total cost so far £0 + free re read of computer next week (this is because they fcuked up with the s55 and are ass kissing due to the new s65 being talked about)
so all in all not a bad day:razz:
