Hi,
Iv had some new bc coilovers fitted about 3 months ago an I hear a knock when I decelerate or reverse could it be the inserts? Its on the rear the noise is coming from!
I thought it was the caliper making a noise but iv had them checked an they are fine.

HELP

if you dont have the rubber top mounts they do knock

Yeah it's a comman thing, mine also knock mainly on the rear. It's to do with the solid pillow ball mounts I believe (someone correct me if I'm wrong). It's nothing to worry about if it is that, just annoying. I believe BC made rubber mounts in the later models to stop the knocking. Talk to Bren at Apex performance, he knows the ins and outs of them.

You should be able to buy the rubber revised version mount from apex in Bradford

Worked for my knocking BC's, now they make no noise what so ever

i had a similar problem when i fitted some in february.

fine for a few weeks the started knocking, jack the car up and reset the preload.

i think the springs had compressed a little with the weight of the car and had become slightly loose between the locking nuts on the struts and knocked slightly under braking or acceleration.

once i reset the preload they have been fine.

that to me ha5ti3? if so explain more please lol i am a newbe at this

ha5ti3

it applies to most coilovers if you get adjustable camber inserts for the topmounts you will eliminate the knok and make car more desirable have a look in the for sale section there no dear but may need a 4 wheel alignment

Thanks for the response guys really appreciate it!!!
I will try the nuts on top an the preload the week end hopefully it will cure it! It's so annoying having knocks.
