hi
I've just discovered something quite odd. When i go over 130 khm on the highway there is an odd vibration from the front of the car. It is a vibration in four succession rapid shakes lasting barely a second, which repeats itself
de-de-de-de....de de de de....with not even a second in between.

The moment i reduce speed a little it stops.

Would be very grateful to know what the members think. THe car is a 560 sel which has a 603 diesel engine in it just for information,

thanks in advance

MJ in Marrakech

Last time I was in Marrakech, the roads were pretty rough! Try rotating the tires before doing much of anything else.

Hey is the Golf Palace still in operation? I supported the space shuttle missions there sitting by the pool. Even saw Gorbachov at dinner one night there with a couple of 6ft tall blonde bimbos on his arms.

I have no idea about the golf palace. BUt i think i'll change the wheel bearings and have them balanced to see if that helps.

I would get the car up in the air and take a good look at all front end components.
Older car, mileage, heavy, = wear and tear on a front end.

Cars change behavior at different speeds and if it's starting at 130
and it is a wear item it will most likely change as the conditions change.

If you are confident in the car, blast through 130 up to about 150 and
see if you can drive your way out of the oscillation.


Good luck.

Could be a wheel bearing... Just pray to the 3pointed star it's not a rear! :-O

Not a "rear"....? We are two great nations divided by a common language

As in rear wheel bearing.

ok but what's the big deal about the rear ones? Are they a bugger to get off?

The fronts are easy compared to the rear.

There should be videos showing how to replace both on youtube.

Check the flex disc and of course tire balance. Could be a bent driveshaft if you hit anything, but the front and rear flex disc are mounted at both ends.

The rear wheel bearings are no walk in the park. From what I heard, you do not attempt them unless you have spare hubs.

Drive line is a good place to start of course after tires and bearings. If you pull your drive shaft, expect to find a flat spot on your U joint. Our drive shafts don't flex in use like a typical driveshaft. Everything is mounted fixed if you catch my drift.

Have you looked at your center support yet?

Thanks. Your advice was good. Found one lower arm bushing had gone and also the little shock absorber for the steering which was finished. Still a bit of vibration but i havent yet done the alignment

Could be the flex disc which holds the drive shaft in place. If it goes while you're driving, the entire car is toast.
