charvezding 0 Report post Posted January 13, 2011 Hi Guys Have been having a bit of trouble trying to figure out why my e28 525e starts to wobble between 90km-100km. I have had the wheels aligned and balanced and had all the bushing and control arms checked at the front and everything seems to be perfect when I get the car just above 90km it starts to shake quite badly, then it will go away and then comes back again intermittently. I'm starting to think either drive shaft bearing, wheel bearing or warped rotors, or even the drive train out of alignment. Any help would be great!! Cheers Quote Share this post Link to post Share on other sites

BM WORLD 1264 Report post Posted January 13, 2011 yes double check your wheels , what type are they?? but normally its the thrust arm (brake arm) bushes or ball joints that fail and cause that problem. and sometimes the brake discs are warpped etc Quote Share this post Link to post Share on other sites

Apex 693 Report post Posted January 13, 2011 Maybe only drive 95km, turn the car off. Reset the trip computer and keep driving Quote Share this post Link to post Share on other sites
charvezding 0 Report post Posted January 14, 2011 I've only had the car for about 3 weeks, just got the wheels balanced and aligned yesterday It's got a set of 225/55 r16 which look like they're off an e39 I had a chat to the mag and turbo guy in New Lynn and he said they could put some spacers in which might help it. and I mean 90-100km/h!

hybrid 1039 Report post Posted January 14, 2011 As others have said, looks like you have e39 74mm hub centric bore wheels instead of 72.5mm bore. The wheels are only using the lugs as centering which is fine for lower speeds however has the speed gets up the wheels start to vibrate. BMW use a hub centric bore that the wheel sits on to center itself properly. Mechanically is a far better system than wheel studs but it needs to be right. You can either get new wheels with the correct bore or ideally have someone like arrow wheels or brugar engineering press 74 to 72.5 ring sleeves in, or get hold of some rings from jono @ Mag & Tire Direct (forum sponsor). If you got the car from a dealer, you might want to try going back to them stateing the car shouldnt have been sold with those wheels on it as its actually causing problems with the vehicle and get them to pay to have it recetified.

Fantastic! I've been trying to figure out what it was, it makes a lot of sense! Cheers man! What are the rings worth? Quote Share this post Link to post Share on other sites

charvezding 0 Report post Posted January 16, 2011 Hub centric rings will solve all your issues. I have replied to your Pm cheers IT WORKS! WOW! What a difference! It runs like a dream on the motorway now, no wobbles at all! I had no idea that a small piece of plastic could make such a difference! Never underestimate the importance of hub-centric rings! I certainly won't! Cheers everyone who posted and helped me diagnose the problem and thanks for the rings Johno! Phil Quote Share this post Link to post Share on other sites
deeveus 81 Report post Posted January 17, 2011 My car had this when I had the 20" wheels fitted a year ago. It was found that they didn't send the rings with the wheels when they should have, was alot of pissing around but we got there. Quote Share this post Link to post Share on other sites
rusteee 52 Report post Posted January 20, 2011 Maybe I should try these rings to. My car has had this same sort of issue ever since day 1. I had all tyres done, balanced and wheel alignment, driveshaft and bearings etc replaced, and various suspension parts done. All of which made no difference. Sorry for my ignorance, but is there anyway to tell wether my wheels need them or not? Its an E36 320 with 17" M3 replica rims on it. The problem sounds exactly like this one stated in the thread.

With calipers - measure the OD of the hub flange & the ID of the wheel Quote Share this post Link to post Share on other sites

There are a lot of "wheel importers" out there that don't specify the correct CB when they get wheels. I would say your wheels will either be a 73.2 or 74.1 CB. If the are 74.1 it is just a matter of fitting locating rings. If they are 73.2 you will have to get the wheels machined out to 74 and then retrofit locating rings, as you can't make rings that are .5mm thick. As mentioned above, take a wheel off and measure the centre. I am actually surprised that the guys who did the tyres didn't pick up on it straight away.
