Noise/shock knock coming from engine bay when coming to/from stop ... what is it? - Honda Prelude Forum

jtown · 01-24-2008, 12:52 AM

I've recently been hearing a noise that sounds like shock knock from the engine bay or somewhere up front when I come to a stop and when I go from a stop. It doesn't happen when I accelerate or stop slowly, only when I sort of come to an abrupt stop or have a jolty start in first. It's most noticeable if I'm sort of rolling back (like out of a driveway or something) and then I need to accelerate forward a bit faster.

Anyone else have this? I have 108k on the clock with about 100k on Tein HAs. Are my shock going out or is this a wheel bearing problem?

Thanks in advance!

Honestly, from what I've dealt with in my other Honda, it sounds like motor mounts... Somebody correct me though.

could be motor mounts, could be a CV joint going bad, could be a loose radius rod.

Yuck. None of those sound very fun. Any way to diagnose which one it could be? Jack up the car and ..... haha.

Or maybe it's time to retire her.

Yes i have the same problem and so does another member here. Im almost thinking its something in shocks because i only seem to notice it in cold weather. However my friend also thinks it may be a motor mount issue. Can you feel the "bump" sometime like in your peddle? Cause sometimes i do and then other times it sounds like its on the passenger side. Weird...

BTW- my ludes pushin 178K miles

You know ... it's when my car is cold also. I don't really notice it as much after I've been driving around for a while.

mine has a def knock when I accelerate only when its cold...I can feel it in the right hand side. i was assuming its shock related...once I have been driving the car it goes away

vtec_07 · 01-31-2008, 10:44 AM

i have the same problem with my 94 lude. Mine was jst the shocks.........

ljastangs21 · 01-31-2008, 02:49 PM

well looks like its just cold shocks.

BlackBB6lude · 01-31-2008, 03:32 PM

this happens to mine once in a while...when its cold mostly...when its above like 40 degrees it goes away

Did you check your link kits they may have seperated and as they move may be poping in and out of the cup, i had this problem about a month ago

mocbaar83 · 02-11-2008, 03:16 PM

Just chiming in, mine does the same thing at under 40 degree temperatures and I am almost positive it is the shocks

Jason01LUDE · 02-11-2008, 04:08 PM

Mine dose the same thing on driver side..... I'm thinking its the shock mount .

twisterfx · 02-15-2008, 10:24 PM

same problem only in cold weather.. every winter it comes about.

Krayzie · 02-16-2008, 11:24 AM

same.... only in cold weather
Most people says it's caused by the radius rod bushing hardening when it's cold out

Does any one have a pic of what the radius rod looks like?
I wanna fix it but have no clue what I'm lookin for

jtown · 02-17-2008, 03:45 AM

Aight cool. I actually think it might be a cold weather thing with mine also. It's not as prevalent nowadays.
