The wheel balancing experience thread

[spyrot1]

Like I said in the OP, braking has absolutely no effect at any speed (well besides slowing the car down). Thus why I don't think it's a bushing issue. Also, I believe the thrust arm issue only manifests between 50-60 MPH, and once you get above 60MPH is not noticable. This is noticeable all the way up to 75 MPH which just screams wheel balance to me.

My balance problem showed itself at 65mph and 85mph... and this was after I replaced the thrust arms with new Lemforders with the 750 bushings.

Then it is wheel balance issue. This is assuming your wheel is in good condition. Look at your weights... if you see like 2.5 oz on one side... on the edge of wheel (not the tape weight in center) then good possibility that your wheel is not true.

I have seen incredible amount of weight on a small 15" steel wheel... which tells me bent wheel.

The most you should see on the edge of the wheel weight is like 1.5 oz... I'd like to see all of them much lower than that... Sometime, I am stunned that I don't need any wheel weight. I'd like to see all like less than 1 oz.

Balancing is a combination of the machine and knowing WTF you're doing. I'm happy to pay a shop their going rate for balancing if they'd just let me do the labor myself. Here's a shot from my 318ti recent tire installation done at a local Tire Rack Recommended Installer (HAH!). I've never seen anything like this. Thankfully they're currently on the rear of the car. Check out the number, mix, and location of the weights, especially the stick-ons on the lateral surface!:

Holy mackeral... That tire is balanced off a bad tire balancer... either not calibrated or bad parts inside the balancer. I have been throught that experience many times. You must have spun it like 4 times to get that balanced.

Also, the stick on, on the side of the wheel will spin off the wheel... it would never hold.

I had a problem before no shimmy but vibration from 55miles up...try checking your guibo and center bearing...it worked for me...http://bmwe34.net/e34main/Maintenanc...terBearing.htm

That was my other thought but I'm replacing both of those next week so we'll see how that goes. The guibo was replaced about 21k miles ago by the previous owner.

I'm also going to check wheel roundness while I have the car up on stands and the driveshaft disconnected, but I'm pretty sure the wheels are fairly straight since I don't recall any particularly large weights on the wheel.

If your center bearing was shot your guibo Might be affected even though it was replaced 21k miles earlier yup while at it check the roundness of your rims and tires aswell...others also your wheel bearing and rotor disks
