At the new Shenendoah circuit at Summit Point this weekend I discovered that I have a bad wheel bearing. I am 99% sure that is what the problem is but there is no vibration and no play in the bearing with the wheel in the air but it makes a horrible noise when turning - kind of like a thrum thrum thrum.... I am going to replace the bearing today but I want to be sure I do the correct side - the noise virtually all goes away on right turns but is terrible on left turns so that means it is the right wheel bearing, correct? Has anyone else had to replace a wheel bearing? If so at what mileage? I currently have 55,000 miles.

wheel bearing replaced. It had 60000 miles when the wheel bearing went bad. It was the drivers side rear wheel bearing. What was odd was once they started they noticed the spring was broken too. They said the bearing was a pain in the butt. I did not do it my self because I did not have the equipment. I think you said you have a bad front wheel bearing. I think the front is very easy to replace. It is much simpler
than the rear.

I really don't know which it is but I know the fronts are relatively easy to replace as I have the tools and have done it and the rears are a PITA to do. The noise sounds like it is coming from the front so I am keeping my fingers crossed.

turn the steering wheel to the right slightly and apply the load to the right side. When I did that the load would come off the drivers side wheel bearing and the load dampened the noise of the bad wheel bearing. The bad wheel bearing was much louder when there was a load on the bearing. I had a wagon so noise in the rear was very easy to hear. It was very easy to tell it was a bad wheel bearing in the wagon.

I've seen 1 car where the wheel bearing didn't have any play when the car is lifted up, but the wheel bearing was def. screwed. I'd go ahead and replace both sides.

I've never had wheel bearings on any of my E36's last more than 50k miles.

My Right front went at about 15K... I replaced both left and right again around 35K... I'm at 53K, and they are still good... In my case, I couldn't really feel it or hear it, but with the car off the ground, there was some play especially twisting from the top to bottom. BMW charged me $650 for the first one, and for the 2nd two, I took it to a BMW specialty mechanic and had both done for right at $800.

The original was not covered under Warranty because of H&R springs and the spacers I was using for my 18" OEM wheels over the Brembos... By the 35K replacement I had switched to 19" OEM (No spacer needed) and Ground Control... I'm thinking the 15mm spacers had a lot to do with it...

I paid <$170 for the parts and do the labor myself. I have the big [Oops!] socket, the bigger [Oops!] socket wrench to get 290 Nm and a gear puller modified to pull off the bearing but other than having the tools, the job is fairly straightforward.

I agree it may be due to the spacers but I only run them with my stock 18's to cover the Brembo's in the Winter.

I replaced both at 28K with same symptoms (loud rumbling noise but no play). Both replaced under warranty since my car is basically OEM (.... but with some track time :^) )<img src="http://homepage.mac.com/booboo/.Pictures/axis.jpg">

I heard it's much more than a Wheel Bearing,, it's the whole Deal behind the front brakes
