rear suspension hitting rim?

Started by delux68, 08 January 2006, 07:28 PM

in my 79 300sd every time i turn right i hear a knocking sound from the right rear tire. upon inspection i see that the inside of the stock bundt wheel is rubbed against and the balancing weight is also marred. there is a   bar that runs nortth/south behind the wheel and above the hub, it has a knuckle with another bar going down to the hub area. the knuckle is what is hitting the rim and the knocking sound is from the weight hitting the knuckle. other that that there are no signs of anything being out of place and the car runs and drives the same as previous to this occuring.
thanks in advance  ???

What you describe is the joint on the rear sway bar.
Either a rubber joint is allowing movement of the sway bar laterally,or rear suspension arms are moving , or you have the wrong Bundt wheels for your model or less likelly the rear hub is allowing movement in the bearings.
I hear the 116 can also rust in the chassis at the upswept part of the frame over the axle and this may allow movement.

I would check your rubber joints first. Might be lucky and it will be simple

just wanted to say thank you. is was the joints. i took the car to my mechanic, he put it on a lift and showed me how to do the repair myself. the new parts were about 28 dollars and took about 1 hour to fix.

Hmm? Other than the 15" bundts, what different versions of the wheel were out there? How can you tell the difference between them? I've never heard of any other versions before...

I ask because I have a "set" of bundts for my 116, that came from various junkyard cars...now I'm worried that they may not all work...

I discovered that when I went to get new tyres fitted. The guys in the tyre shop couldn't get valve stems to fit my "bottle-top" ("bundt") alloys - the rim material was just too thick.

I asked my parts supplier (an M-B specialist) and he requested the numbers from inside my wheel centres (and there were nine sets of numbers!).

When I e-mailed him those numbers, he informed me that I had an unusual version of the wheels made of thicker than standard material, and that he would get me the correct valve units for them from Germany. They were all metal and, I seem to recall, made by Bilstein!  So how to tell the difference? First, check the thickness of the material. Second, check the numbers on the inside of the wheel centres. For what it's worth, the numbers on mine are:

A: between "spokes"

6Jx14H2

1084000902

127760 c

7 (in a circle)

B: on the flat "hub" surface:

AS10 62

4979

31

3

2 (in a square).

I wouldn't be surprised if the part number - beginning with "108 ..." - indicates that my wheels were originally intended for a W108 - yet my W116 is a Dec '79 manufactured UK-market job. They came with the car, but I don't know if they were original factory-fitted equipment or later add-ons.

So it would seem that there are at least two version of the "same" wheel.

Mercedes outsourced the manufacture of their bundts to various wheel manufacturers over the years. 

Correct fitment for W116 is 6.5Jx14"
I have also seen cosmetically similar 6Jx14" and even 5.5Jx14.  The 5.5's came from a W114 I believe. 

I have in the past had about a dozen 6.5Jx14" bundts lying around in about 4 different cosmetic versions.  (the manufacturers included Fuchs, Oz and Centra I think - possibly Dotz too? - can't remember now.

Oz - from the specs you list -

A: between "spokes"

6Jx14H2
rim size

1084000902
the part number starting with 108 is the Mercedes number - and yes that means that that particular design was first commissioned during the W108 era.  But it can still be correct for the W116 era.  Mercedes do tis often - use existing parts in subsequent generations without changing part numbers.  My R107 has some suspension bushes with 114... part numbers because they are "borrowed" from the 114/115 sedans.  Likewise my W140 has a lot of generic type things like clips, beadings etc with 126... part numbers.

probably the subcontract manufacturers number

4979
this could be further digits in the manufacturers number, or otherwise a manufacture date ie 04/09/79
Even if this is not a date, there is usually a date somewhere on the wheel.

31

my guess is this is the offset - ET31

no idea

no idea

As an aside, the date is often represented as the year of manufacture in a little circle - ie 77 or 78 for exampl in a little circle.  If you look really closely, inside the circle surrounding the year number are little raised dots at points like the hours of a clock.  If you have one dot at the 1 o'clock position, it was january of that year.  another example - three dots at 1 o'clock, 2 o'clock, 3 o'clock - March.

OK thats enough useless information.

Ryan: Thanks for the interpretations!

If you're right about the manufacture date, then those wheels were "born" on my 30th birthday! Good Virgo wheels.   :)
