Hi everyone! I have an 02 sle and every morning or after about 1hr parked when I turn my steering wheel for the first time (either way) I hear a loud clunk/boing that i can feel in the driver side floor. I do not feel it in the steering wheel column however, and it only happens this one time. I just had new tie-rods and wheel bearings put on, not for this reason, but this was happening before and is still happening after all of that. Does anyone know if I should try to lube my strut bearings as a possible cause? Any suggestions would be greatly appreciated!

Thanks SO Much!

I think there is steering shaft knuckle problem with the newer Bonneville'* that bang and make all sorts of bad sounds.
There is a way to lube it up but by the time you get to it you might as well replace it.

Do a search for Bonneville 2000 and newer steering shaft knuckle problems

Did you read this? It might hep.

Thanks for the help guys. The noise itself does not come from the steering column or shaft. I do have the slightly common clunky steering, but this is something totally different. I lubed the strut bearing today at work and I didn't here it once at all after that. The true test is tomorrow morning after she'* been sitting all night. I'll let you know if I was able to solve this issue this way.

How did you lube the strut bearing?

high quality aircraft axel grease from my fathers job. worked great

don't know how he did it..but..
open your hood and on both strut towers there is a black dust shield that is at the top of both towers.
remove it and look for 3 holes in the bearing. put a good quality oil down those holes.
