Wierd Sensation !

[Daeths]

I have a E320cdi W210 on a 2001 plate. I love her to bits and she has a very careful 85,000 full mbsh.

I am working my way through the niggles and have two left (all the others have been fixed via this forum, so thx to all). The one is question is:

When travelling over 60'ish i get a vibration which is not just steering (i.e. tracking) but through the whole car which I can feel from the seat...no jokes required !!

Reading through my gut feel is prop related (??), if so what are the specific components it could be and how would I test ??

Re the symptoms, interestingly it does not appear at the same speed but can alter from 60 all through to 100. I have non MB wheels which are 225 x 17 x 45 which are the 5 spoke AMG style, offsets all match etc. Have had the wheels balanced several times by a buddy who did it digitally. The wheels do have the plastic inserts to ensure they fit the rim properly.

The warranty is shortly to expire and my friendly garage are going to "MOT" it to see if any problems exist before the warranty expires, what should I point out to him (he's not a muppet, but he's not a Merc specialist.)

Appreciate all and any assistance.

Thx

Adam

When it afffects the whole car its normally a bent rear wheel. However the center propshaft bearing can also cause this.

I'm not sure of this plastic insert , I thought the hub location was metal to metal. Chris Murray should be able to let you know if the wheels are right for the car. If they aren't centred correctly then no matter how much balancing you have done they will never be centred so the car will wobble.

blobcat's bang on

jack up one of the fronts and spin the wheel to make sure it spins true with no up and down movement.

i'd chuck them plastic things as far as i could and either get machined metal concentric spacers or some of the hubcentrics that chris has posted about.

or better still ..wheels that fit the hubs properly.

Me thinks you are probably right, will jack and spin. If the plastic things are rubbish (and it sounds like they are) and I don't want to chuck the wheels (which I really don't) any ideas where I could get a metal "insert". I believe the idea of the plastic is because the diameter of the rim is mariginally biger than the 'flange' (?).

I have a spare one of these pieces of magical plastic and it has on it 0 70.4/0 66.6 (the "0" is in fact a 0 with a slash through it).

Must confess I did not notice it before the new wheels, so it looks like your right.

Appreciate any further assistance.

Metal insert called spacers or plastic I presume can make your car un road worthy, this is stated in some hanbooks.

What this means is that if your car was in a single accident and MB were called to investigate they would say that it did not conform to the original certificate

Thx TV (good to see you back). The more I read (and quickly learn) these spacers are not good. I have PM'd Chris Murray as recommended as metal must surely be better than this crappy plastic thing I have in my hand (sounds like a Carry On line..)

I really want to keep the wheels if I can, but if this is my problem they are ruining my ride post 60mph...but interestingly not always ??sometimes it's 70mph or 80

YEEEEE-HAAA!

Both Malcolm and Eric back in action!

Jees, it's been slow around here without you guys - and for oursakes, what a Godsend that you both came back.

Even when tempered with a competitive spirit, there is no substitute for the experience and dedication you bestow on this forum.

Hi
These plastic things are not called spacers.
They are called spigot rings

should these spigots actually be metal/are metal better than plastic do you know ?

Hi
They can be both.
I have only used plastic ones.

If you eliminate the wheels & the vibration is still there, it could be the torque converter. The symptoms are usually 60-80mph going uphill & accelerating very gently. The car can be heard & felt to vibrate & it does feel like the rear wheels. A road test with a Star diagnosis on board can switch the lock-up clutch off to see if the problem stops.

Well this is a very interesting idea. But you must eliminate the wheel thing first, as the wheels are usually the culprit, especially the rear. The reason I say its a good idea is because you have said it happens a varying speeds and not a constant speed. Convertor can cause bad vibrations at almost any speed, whereas wheel problems are normally 80 - 100 km per hour

Thank you for the post, Greenfingers and yes I love this Forum, i am a member of many other Forums but not to do with Benz, except one. But my posts fade into insignificance compared with the amount of work Malcolm has done for this Forum and I too am happy to see him back to bussiness as normal
