Since you say your wheels and tyres are new. There is a change you could have a distorted tyre. This can happen at manufacture. Usually difficult to balance but can balance out ok. I had a civic type r with a distorted tyre on the rear and at 75-80mph it sent a strange vibration through the car. One of the tell tale signs is the high speed than normal out of balance wheels which is usually between 55-65mph.

The other thing I can think of is that the allignment should be set after new arms and new wheel/tyre package. Also did the new wheels fit the hub centre perfectly? If they require spigot rings then you would know all about vibrations!

Ok, BAD NEWS!!!

As i posted couple of weeks back my vibration had been resolved after new axle and took the truck to butler tire and had them highspeed balanced and alignment etc. so afterwards things were good. So after about 1,200 miles I have to say that its back. once i hit 60+ i have a slight shake in steering and before it starts i can feel the vibration slightly and then as speed increases the steering starts to shake. Now its extremly evident in the morning after a bit of driving it feels like its gone but i can see my water bottle shaking....So it was suggested to change teh trust arms so ordered a pair and new ball joint also for each side.

Also i feel like teh car is pulling to the left again even after the alignmet it was going straight but now its started to vibrate and pull left.


so yet again any options.

Bummer!

Ok, your tires are balanced and not "out of round"?

Check to make sure your steering rack is nice and tight. I don't think we have a steering guibo, like the 325i does. That made the steering sloppy and vibrate.
Thrust arms (forward unit) and Control arms (lower) and ball joints need to be fresh and get another alignment.

Good Luck!

regarding the thrust arms i dunno if there was any play in them or if they were bent then yes remove/replace. did you change one of the axles??? i think both should be replaced at the same time.

I know you said you like that shop..... But after you go there you have problems. Couldn't hurt to balance them else where.

The thing is that ive had them balanced at 3 shops now one i didnt mention but first it was where i bought them discount tires ( balanced twice and after a week vibration came back) then i forgot the name of the 2nd shop they used hunters machine thing and similar thing then went to butler tire and i was able to drive for 1,200 miles so about 3 weeks for me and now its starting to come back. I feel that its sometime with either alignment but i have had it aligned 3 times now....it cant be coincidence that it looses its alignment so fast and im not driving rough or through pot holes hell ive been babying the damn thing. I guess after i change the trust arms and ball joint with bilstein brand ill see thats my last step....if the vibration comes back its gonna be traded i cant stand this. ive added my bills up so far im over $4000 in repairs just suspention. its still cheaper than buying and paying monthly for a car for me at least. ill see parts will be here in a day and ill see how things turn out.

Bentley's after-market Service Manual for the X5 says that out-of-balance at 60 mph, particularly under braking, is most likely caused by loose bushings and ball-joints in the suspension linkage, than by warped rotors, etc. If you've balanced the tires three times by three different shops, the balance is NOT the problem. Jack the front wheels off the ground (support it securely w/ jackstands), and have someone shake the wheels while you lie under the car, and feel each of the four linkage arm ends, in turn. There are two bushings at the chassis end of the links, and ball joints at the wheel ends. Total 8, two bushings and two ball joints on each side. On my car, three of the four had noticeable play, on each side. Replaced them and the problem went away. Just got back from towing my motorcycle on a trailer from south Florida to Lake George, NY, 3000 miles total, NO PROBLEM! Forget about the balance - get under the car, and check the bushings and ball joints! (Insanity is defined as repeating the same actions, and expecting a different outcome.)

The problem is i did replace those parts all of them at once and still had issue. Now i know i bought the cheap kit off ebay so i replaced the LCA with brand name and still had same issues. The second step was the good year tires were actually out of round so after replacing them with michelins the problem was softened but still there. after alignment and rebalance things were good for like 3 weeks and its back so the only bushings left are the trust arms from the cheap asian/german company but i did as you said shake the wheel and there is no play in them non. However, i ordered 2 upper arms with bilstien and ball joints so thats it no other part is left thats from the cheap asian/german kit. I can say my steering rack those make a click but its definitly from the u joint in the column i can feel it tic toc when turning left to right etc. the left whole axle with CV joint was replaced also because it was very loose and the right is only 2yrs old dealer replaced it in the end of 09 and its still very tight and no play. i will see midweek i shall have the parts in and replaced. we will see I really hope this is it.

Hello, I'm not sure if it's the right way to say it, but did you make some adjustments for toe-in and steering wheel alignment? And how 'bout bearings? Are they tide enough? Full suspension check is strongly recommended too, transmission joints and all rubber pads. My tech English is not good enough. But if your wheel alignment is not done, you can have lots of things out of order.
