Vibration 80km/h and above

[MGO_BMW]

Hi all.

My 2006 BMW 320i is driving great.

I just have one concern on my mind.:dunno:

When traveling at exactly 80km/h and above i get vibration through the body of the car and only when torque is applied like under acceleration when deceleration or no torque is applied it runs super quiet.

I have no steering shake or any thing.
Want to get the wheels balanced (high speed balancing) but not sure it is the wheels.

Any thoughts on what can be the issue.

Sounds like balancing... does it go away after a higher speed say 130kmh?

General rule of thumb on vibration and wheel balancing:

If your steering vibrates, your front tyres are out of balance.
If the car vibrates, your rear tyres are out of balance.

Not a hard and fast rule, but just a good indication.

start with wheel balancing, its the cheapest anyway,so start small

As the others have said check for the obvious first. Also don't count out the chance of a buckled rim too...

I had a similar problem, after Mintys messed up the balancing twice. Took her to Motorvision in Pretoria and they sorted it out. Only company I've seen in years that still does high speed balancing on the car for the front wheels.

They're not cheap. They're damn good and efficient. I live in Roodepoort and all in all it was a hour 45 including travel time there and back. When last have you seen more than one person taking the wheels off your car?

Told them the problem and instead of the usual bs they balanced the wheels and checked the suspension. They didn't do the alignment because they knew the symptoms had nothing to do with the alignment.

Will only do my balancing and alignment there in future. I don't mind paying the school fees - I hate repeating the grade:dunnoanymore:

It could be the above as others have said, but what gets me is when the OP says it happens "when torque is applied" so this makes me think it could be something on the drive system. Universal joint or something perhaps.

Start with balancing as it's the cheapest to rule out, though.

Exactly my thoughts as well want to check prop shaft when i have time. But will also first check balancing.

For me, the fact that it's smooth under no load would rule out unbalanced or buckled rims. Like previously said.....a vibration through the body would suggest the rear of the car.

Propshaft balancing
CSB
Rear cv joints
Universal joints
Guibo coupling
Rear bushings.

I think these could all play a part in causing a vibration.

This is just my 2c from experience with buckled or unbalanced rims. I could possibly have left out a thing or two.
I've had three sets of wheels on my car and I still get a jiggle at ~35kph under hard acc.
This leads me to believe it's in the drivetrain.

Hope u get it sorted. I know how frustrating it can be.

Does anyone know of a place that does high speed wheel balancing in KZN?

I had a similar issue of vibration between 70kms and 90kms, took the car to TwT for balancing, problem not fixed.

took it to motorvision, problem gone with just balancing :thumbs:

I have been fighting a vibration issue for some time on my 2004 320i auto, after gearbox select in Pretoria did a (dubious) torque converter recon. There is a thread about this problem on this forum.

Could certainly be propshaft so once you have eliminated wheels and tyres, this will be your next angle. We are beyond propshaft issues now, looking into flex-plate, torque converter matters.

Good luck. I will post on my thread once we have made further progress.

UPDATE on this.

After many vibrations it is fixed.

So i wanted to replace the Guibo and Prop CSB.

Went to tackle this this morning and to my surprise the bolts on the guibo one has snapped in half , one missing a lock nut and only one kept holding the whole thing in place The other 3 from the gearbox was still ok.

Inspected the Guibo and it was stil good. checked the play on universals seems to be good also and the center support bearing is also ok.

Went to Bolt It (Cape Town) with sample of the bolts and lock nuts needed (M10 x 1.5 x 60 grade 10.9).
After a discussion with sales rep i replaced the old bolts and nuts with new Allen cap nuts of the same length but stronger grade.(M10 x 1.5 x 60 grade 12.9).

Fitted them tightened and torqued down.

Went for a test drive took the car through all the gears up in speed to 120 km/h and there was no vibrations any more.

So i will test the durability of the repair and update.

Thx for the feedback :bravo:

UPDATE

up to now around 1200km all is good.

The bolts and my workmanship seems to be holding up.

Thanks all for the help and input.
