Help! Steering gear problem!
 

Hi all! Here is the situation:

Last week, I put my X to BMW service center to replace the cylinder head gaskets, dustcover of left tie rod and rubber bushing of both upper control arm (tention struts). After I got back my X, I found that there was some noise when I turning steering wheel (both sides) during driving. So I put my X back to BMW service center again for inspection yesterday. Today, the service advisor called me and told me that the noise was come from the steering gear and the whole steering gear needed to be replaced. WTF!? I immediately made complaint that the steering gear had been working fine without any problem before I put my X to them for repair, how come such serious problem happen after the repair. It just does not make any sense!

Experts here please give me some advise, is it possible that such problem happens suddenly? Is it possible that the dealer did something wrong during the repair that resulted in such serious problem or it is just bullshit by dealer? What should I do to this? Anyone here has the same experience? please give me some advise!!! Thanks for help!!!

Hellooooo! Anyone can help me or give me some advice over this? Thanks!

Well, I guess no one has any idea on this.

keep checking back rogerkiu...

Finally I found the problem!!!

First I just asked BMW dealer to reflash the power steering fluid to see if it can solve the problem, it only costed me about US$70. After that, the sound still exists. Then I put my X5 to a garage to replace the engine mounts and auto transmission gear mounting, the people of the garage told me that they found some sound coming from right lower control arm. Suddenly, it reminded me that last time I DIY replaced the right lower control arm, I did not replace the long screw, just replaced the two self-locking nuts. Then I checked TIS, and found that it reqired to replace both nuts and the long screw. Then I went to the dealer and bought a set of nut and the long screw, I replaced the nut and the long screw by DIY, then after over 100 KMs driving, I hardly hear the sound (sometime I still hear the sound but very very slightly, much much better than before). I think the problem may be the right lower control arm, since I used the one made by Febi, not BMW oem product. I believe that the sound will goes away if I replace the control arm with a BMW OEM product.

By the way, it really feels different after I reflash the power steering fluid and both engine mountings and gearbox mounting. Now my X5 drives like a new vehicle!!! Lovely!!!
