Hi,

I have an E38 728i, I used to have a wobble coming up through the steering wheel, like a wheel was not balanced properly. I had this checked and what was found was a steering idler bush / pitman arm push had worn and needed replacing. I know this would not cause the wheel to move, but would exaggerate the effect. I Had it changed and all 4 wheels balanced. The wheel does not wobble anymore, however I can still feel a vibration through the steering wheel, that soemthing is loose or not right.

Does anyone know of a reliable mechanic who understands these cars and sort the problem without it costing me a bomb? I'm in the Redbridge area so can get to most places in Essex, London and Hertfordshire.

Your help greatly appreciated. Thanks

Have added your problem to your thread title...:thumbsup

As Neal suggests, You may be best to get a laser hunter alignment done :)

I have had all 4 wheels balanced, which stopped the steering wobbling. I did not get the steering geometry checked as the car is not pulling to one side or the other. It is steering straight. But if this does help to locate the problem, I will look into. Can anyone recommend someone for this? Seb thanks for correcting my thread, new to all this.

I had a somewhat similar problem with my E39, under braking it became worse and i had a warped disk, i changed this and had the wheels balanced. this took the problem away of the shaking but i still got the vibration. It turned out to be a small flat spots in 2 of my wheels. Had them sorted by an alloy wheel specialist £40 per wheel and now its a smooth ride.

I was very skeptical about this being the problem as it felt like it should have been something more serious but it my case it was a simple as that. Just to add mine did it around 65 to 80 mph.

Hope this helps

cheers

There's a lot of rubber in the front (and back) suspension and it does get twisted about a lot under normal steering. These cars have a bit of a reputation for this around the 50/60 mph mark. The cure really seems to be to got and replace all the front end bushes (you can get poly ones).

Also check the back very carefully as there are lots of balljoints that can and do start to get play.

After all that's sorted out you need to get a four wheel alignment as all sorts of bits are adjustable.

Thanks the purpleblob, your post has hit the nail on the head as my car does this at 55 to 60 mph mark. I know it's not the alloys as it did this on the 16 inch alloys and still does it on the 18 inch alloys that are on it now.

E38 2000 728i - vibration through steering wheel

Hi Guys. I'm getting similar issues with my 2004 E65. Could some of the things mentioned here affect my car too?

It's the wobble/shake around 60.

It also shakes a lot when braking from speed, like approaching roundabouts.

Thanks in advance!
