Loud knocking coming from the front after lowering

---

This one has got me completely.

I fitted a set of Apex lowering springs to my car last week. Immediately on the test drive it was apparent there was a knocking from the NS front. Took NS front leg off again, stripped it down, and checked everything was correct and put it back together again and refitted it back to the car.

I came to the conclusion it was probably the anti roll bar links. Swapped these over this evening for a set of new ones, knocking is still there although not as pronounced, but still clearly evident and still just as annoying.

The strange thing is you can pound it down a bumpy road and its silent, go over one small bump and you get a loud knock. I've had the car up and down on the jack and i've checked everything and nothing seems evident. I cant find any play in anything and the springs are completely under compression and sitting where it should when the car is jacked up so i know the spring isn't moving.

Before i go down the road of replacing all the lower arms and also the tie bar bushes (Have a set of orange polybush ones to go on) is there anything i may have missed?

Let's block ads! (Why?)
