I have an 89 Olds Cutlass Supreme that is in fantasic shape. I make
sure I maintain it the best that I can.
Anyways, last month it all-of-a-sudden started making a "knock, knock,
knock" sound sometimes when steering slowly. It makes no noise at all
if going straight. Sometimes when turning quickly I will hear a quick
"knock" or two but it's not as bad or noticable as it is when I am
Sometimes I can't get it to do it, but I've found out the easiest way
to ALWAYS get the noise to happen. First, I park, stop, put the gear
shift in Park, wait a minute, then put it in Reverse, back-up slowly
with the steering wheel turned all the way to the left, once I am
backed-up, put it in Drive, and turn the steering wheel all the way
back to the right, then start to accelerate slowly.
If I do this, what will happen is that it will "knock" about three or
four times while backing-up, and then again when I turn the opposite
way and start to move forward. After this, it's pretty much completely
random...sometimes it will make a quick single "knock" here or there
and sometimes it will be completely silent. But if I always do the
above parking and backing-up procedure, it will always do it.
When the "knock" happens, I can kind of FEEL it in the floorboard via
my feet. I've been in the passenger side while my mechanic was driving
and I could FEEL it in my feet on that side as well, even though it
SOUNDS like it's coming from the drivers side wheel well.
Further more, I took the car to my mechanic of 3 years now and he
found that my drivers side ball-joint was worn pretty good. The
passenger side one was still in perfect, solid condition. It kind of
surprised me because I replaced both ball joints 2.5 years ago and I
thought they would last longer than that!? But I thought, "oh well, at
least the knocking will be gone". I was wrong! It STILL knocks just
like before with the new ball joint!:(
I took it back to him and he raised the car to look underneath. We
both looked for about half an hour but couldn't find ANYTHING that
would cause it. Everything was nice and 'tight'. Over the past 2 years
I've replaced both wheel bearings(hubs), upper strut bearings, ball
joints, and tie-rod ends.
My mechanic said he honestly doesn't know what the heck it is. He said
it could be a worn U-Joint in the axle but said that is still a long
Last month I had both wheel bearings replaced with new ones. What I am
trying to think is whether the noise started BEFORE, or AFTER they
were replaced...if the noise started AFTER they were replaced, what
could the place that installed them done to cause this sudden annoying
Sorry for being so long but I wanted to give as much detail as
