2004 X5 - questions and concerns

[puffjaon]

Hello all, I have been searching and reading before I asked this question as I have been hammered on other non-bmw sites.

As I said I have an 04 X5 4.4 and two things are concerning me, every once and I while it feels like one of my front tires goes out of balance and it gets worse when the brakes are applied. It may only last a few miles and then stops. So I put the car up last night to check all the suspension parts and nothing feels really lose. The one thing I notice is a bit lose are the thrust arms, by lose I can move them with my hands but no clunking or crazy lose. The other thing I noticed was the passenger tire (both we up and the car was on jack stands) did not spin as freely as the drivers side. I am going to take it to a very good mechanic but even he said that you tend to just start replacing stuff. Maybe time to trade it in on a new one?

The other thing I have noticed is that when the car is in park and on the car makes a whirring sound, to me it sounds like the fuel pump is making the sound.

Any way, thanks in advance and Happy New Year
