Knocking sound after bumps - 02 Civic

This question applies to a 2002 Honda Civic Coupe LX. It has a 1.7L four cylinder engine with about 98k on it.

Several months ago I started noticing a popping or knocking sound coming from the front driver's side wheel well. It is not a continuous series of pops or knocks as is often symptomatic of a failing CV joint. Rather there is a single loud pop that eminates from that area of the car whenever I hit a bump or cross uneven pavement.

Today I replaced the front driver's side strut thinking that it would solve the problem (doing so to the front passenger's side strut solved a similar problem last year). Upon driving the car after the strut replacement, the popping sound was still there.

Do I need to replace the rubber mounting pad that goes between the spring and the top-plate of the strut assembly as well? I didn't do this today, but another source I read suggested that when these pads wear out they can cause the knocking sounds I'm hearing. I wanted to get a second opinion though on this forum.

Any other ideas? Am I on the right track?

That is a possibility. Visual on the rubber looks good or bad? You have mentioned the CV axle and you seem to have ruled it out. The CV axle is designed to flex and to expand and contract as the vehicle bounces on the road. The movement of the CV could be hindered and causing that sound as it attempts to slide. It could be that it only happens when in a certain postion. Thought I might throw this in as an idean.

I wish I had enough experience to say whether the rubber looks good or bad. Regarding the CV axel, again it is my inexperience talking. I though that CV trouble voices itself with a series of pops during a turn rather than single pops like I'm hearing. How would I go about diagnosing it as the CV joint?

Compare the rubber from one side to the other. On the CV it is most often the condition you mention. Are the boots in good shape without any tears?

Take a look at the sway bar ends, there are sway bar linkages on each side and most likely they are worn out.
It took me replacing struts and Tie rods to finally find those little guys. They were about $13.00 each. Simple to replace.
Good luck
