Shudder at speeds 140km/h +

[Vinash]

Good morning all, so yesterday I took my car 2007 E92 325i coupe A/T to R&I service centre for oil service and handbrake adjustment. on my way home after my service I felt a shudder on the car overall at speeds 140 + even when I tapped off the accelerator so I pulled over thinking that my rear tyre maybe loose – so road side assistance came through and checked (runflats so no jack or wheel spanner) all my nuts are tight, so I decided to drive on to the nearest tyre and suspension shop. They said that they might have swopped the tyres around so they recommended doing balancing… so I drove off and the shudder was still there – so I took it back to R&I (where I serviced it) and told them that I experienced a shudder and I did balancing etc etc, so they had a look and told me that my rear rims are slightly buckled (which I find hard to believe because the tyre shop should have reported. So R & I insisted that the “slightly” buckled rim is the cause – I insisted that on my way to them for the service I never felt such shudder only after I drove off from there workshop I experienced such. So has anybody had a similar problem before? (and when I asked them about the handbrake adjustment all they say is they remove the wheel and tighten some screw or something)

Maybe check your wheel alignment as well.

Wheel alignment has jack to do with vibration definitely balancing they must of test drove your car and slat a pothole now they pretending they know nothing of it

The place that did you brakes probably didn't tighten it the correct way / sequence and that caused the slight buckle?

Have someone led you their wheel/spare and see if it goes away.

Shudder on the steering wheel isn't alignment. The most common causes are flat spots on the tyres, balancing is out, rim is buckled/damaged and isn't 100% round, wheel hub damage, suspension components. There are a few other possibilities but the above mentioned ones are the most common.

Do you have OEM or aftermarket wheels? Reason why is ask is some aftermarket wheels require spigot rings, but OEM wheels don't. This will effect what I have to say below.

Since you said the problem wasn't there on the way there, and that they removed the wheel to do the handbrake, the first things I would check are:

- If you have aftermarket rims, make sure they put the spigot ring back on that wheel. If they didn't then the rim won't sit flush and will create vibrations at speed.
- Get balancing done at a reputable place, and make sure all readings are 0.000. (Stand there and make sure yourself.)
- While balancing is being done, ask the guy to check and see if the wheel is running straight while it is spinning. No buckles/bends to the outside and inside of the rim. (You should also stand there and double check).
- Get alignment done. This has nothing to do with the vibrations, it's just good practice to make sure your tyres are running straight and all is well.

If after all of this is done and you still have a shudder, then check the tyres for flat spots. Although you shouldn't have any because you said the problem wasn't there beforehand, it is still possible that they locked the wheels when taking it for a spin after the service, thus creating flat spots on the tyres.

If after all of this is done and you still experiencing problems I would go to a place that specialises in high speed balancing. I know of a place on the East Rand in Boksburg that does this. The normal tyre place does balancing at 60km/h IIRC with the wheel off the car and on a machine, whereas this place does it at 120km/h with the wheel still on the car. They are able to diagnose if the problem is the rim, tyre, hub, or even suspension components.

Sorry about the essay, I got a little carried away there. :blah:

I had a shudder one the wheel of my e46, turned out to be the control arm bushes & one of the threaded holes(which to secure the bush bracket to) on the body was striped, had to have it fixed with a hex coil.

It is most probably something along the lines of the suspension that is tired.

Thanks guys for the help.

I was watching them closely so they never take my car for a test drive they just moved it from the workshop outside to the wash bay. Surface was good.
My rims are OEM. Maybe ill do the wheel alignment and the high speed balancing – can you give me more details of the place?

Unfortunately I don’t know much about cars especially identifying worn out or broken parts – and neither do I know of anybody who would assist in lending me 2 rims and tyres 

My plan of action is:
1) Take it for high speed balancing – if not solved
2) Take it to a specialist to check it out ( any recommendations? )

I need to get my car 100% because next year im on a new venture so ill be travelling from Pretoria west to Vereeniging daily for a month or two till I find accommodation.

I see you are based in Midrand, I suggest you contact Ross Duncan. I send my car there for work that I can not do myself. His service is good and his prices are reasonable, Click for Info

POA steps sound good. Do the high speed balancing and if they can't sort out the issue then go to Ross Duncan. He's great from what I hear, and if you don't come right he'll probably be able to assist.

Also, I actually forgot to ask. Are the vibrations through the steering wheel or does the entire vehicle shake?

If the vibration is on the steering, it is most likely balancing.

If the vibration is in the car (like under your seat or things rattle), it could be that the rims are not 100% straight, the tyres are slightly out of round, tyres have flat spots or the tyres haven't been fitted perfectly to the rims.

The only balancing machine that I know of that can diagnose this properly is a Hunter GSP 9700 road force balancer. The normal balancing machines at TWT, HiQ, etc, will balance to zero even with the above problems.

ExecQ Tyre in Boksburg have this machine. The machine will give you a print out of whether it is the tyre, rim, or tyre to rim fitment issue. They are the only guys I know with this machine.

IIRC they were charging R80 a wheel a few months ago.

Check out their website for more info.

have you checked Tyre pressures first ?

tyre pressure is all good and filled in accordance to the tyre spec.
