Thunking noises after ALK install

Drag-On · 05-08-2007, 07:02 AM

I installed a Whiteline Sport ALK a couple weeks ago ago and since then, I have been hearing thunking/thudding noises coming from the front end when I drive over uneven pavement or when I approach speed bumps. The noises are coming from the ALK/lower chasis area. Is it normal to get this type of noise or did I install the ALK incorrectly?

No. I'd get under there with a torque wrench and re-torque all the bolts (3 per side). Repeat after 1000 miles even if its quiet.

do you have an h-brace? if so, do some more searching, metal may be contacting down there. i saw a thread about it once.

I will give that a try. I know that this mod adds NVH but I grew suspicious when I started to hear unusual thunking noises.

No I don't have an H-brace. My subframe is currently stock.

mine are dead silent, so something is not right.
sorry, can't be of any more help than that

Same here absolutely silent...although my struts make noises when they hit the bumpstops...

nothing some RCE T2's in the next week or so will fix though!

Again, just get down there and torque those bolts down to spec...also, be sure to put a good amount of grease on them to help keep them silent.

Kind Regards,
Ryan

It turns out that the person that helped me install it flipped the ALK when installing it. The bottom side was facing up and the top side was facing down. I reinstalled everything and there is no more tapping/thunking noises anymore.

Well...that would explain the thunk
