First off, Thanks to everyone who gave me advice about new brakes for my 5401. You all save me a lot of money. Okay everyone, here is one that is stumping the BMW dealer and mechanics. I have a 95 540i with 63k miles on it. I bought it about 7 months ago with 55k miles. It had the original rims and tires on it and drove perfectly. I bought 17" OEM 5 spoke rims from a 97 or 98 540 and put on Dunlop SP5000 tires. The test drives were bad, the car had a shimmer. They rebalanced the tires and got the shimmer down a little. I finally took it to a BMW dealer and had it aligned and the tires rebalanced. Still had a problem... A few months later, they put it on something called Road Force which simulates the weight of the car on the tires and spins them and gives a computer read out. The dealer said the tires were out of round. (I don't have the highest faith in this dealer though) Anyway, I got new rear tires put on again... Same problem. The problem is this: 0-45 everything if okay, around 45-55mph I get a shimmy in the front end, I am convinced it is in the front right tire, the steering wheel wobbles a little. From 60- 70 it is okay. Around 75 on up the vibration feels like it is coming from the rear tires. Now the real killer, sometimes it is real bad, sometimes I hardly feel a thing. This can be in the course of 10 miles. I had the car suspension checked and everything checked out oaky. The front tie rod has a little wear but they said it is no where near needing replacement. HELP!!!!
