So I just got ISC Coilovers for my 2008 535xi and I put them down fairly far, just so the fender was slightly lower than the top of the tire with stock wheels and tires, and now there is a clunking noise when I drive that increases with speed and continues when I am in neutral. I am pretty sure that it is axle bind because it went away once a raised the coils up. Once I get bigger wheels I am hoping it will not even happen when I get the coils set where I want them; but does anyone have any other ideas on how to fix this? Or know if it could be anything else? Thanks

 

Did you replaced your strut mounts.

 

You mean the collars that pinch around the bottom of the strut? No I didn't they're part of the main hub piece. The problem is only on the front by the way, I forgot to mention that in my earlier post.

 

Any solution, i dont understand. When i installed coils on my e60 i also had the clunk. i replaced the top strut mount and i put 2 washers instead of 1 then the bolt after. maybe make a video so we hear the noise.

 

I did replace my top strut mounts ( they came with the coilovers) but i did not put in washers. Im not totally sure how it could be the strut mounts because the problem is related to how low i set my coilovers and the speed i drive, it has nothing to do with going over bumps.
I called the dealership about the front axles on my car and apparently I bought it with the wrong axles because the part numbers didnt match. Not only do i have the wrong ones, but the ones i have are the same length and part number side to side when they are supposed to be different so I am fairly sure this is the problem, I just have to order new axles but bmw ones are super expensive.

 

I had a similar issue when turning left while the ride height was set low. I adjusted my sway bar end links and it went away. You may need to lengthen the sway bar links.

 

Thanks Ill check that out too. my coils came with adjustable ones so they should be easy to mess around with

 

Yeah you should always do an alignment after installing coils or any suspension!

 

how did you lengthen them ? I am dealing with a similar situation.

 

i think i need adjustable endlinks then
