Random Front End Vibration - 2005 Maxima
 

I have tried everything I know and would love to hear any other ideas from the maxima.org people. I have a 2005 Maxima with 210k miles that runs amazing 90% of the time. Some days it runs very smooth and then other days it will randomly vibrate at about 45-50 MPH. When it is running smooth everything is perfect including smooth breaking. When it starts to vibrate, touching the breaks makes it worse. Here is what I have done so far:

1. New tires (balances 3 times and torqued to 85 PSI)
2. New Front Strut Assembly's
3. Replace inner and outer tie rods
4. Replace both lower control arms
5. Replaces both drive and passenger axles
6. Replace both front and rear bearings
7. Replace rear shocks
8. 4 wheel alignment after all parts were replaced

After all the work above the problem got better, but still a problem. Any thoughts on what else could be causing this would be awesome. Thank you in advance!

I'm currently going through a similar situation with my 2004 maxima, I get heavy steering wheel vibrations around 50 mph on most roads.

I recently replaced my rims (old rims were peeling and 1 had crack causing leak), new tires, brake pads & resurfaced rotors. When they were doing alignment they pointed out my rear stabilizer bar was missing a bolt so they added one but stabilizer bushing was broken in half and missing upper part (pictures above) so now I'm wondering if that is what is causing my steering wheel to vibrate? Any suggestions? Fyi the rims are brand new from a 2014 model.

I just ordered front and rear stabilizer bars and will install them this weekend and then another trip to the alignment shop. Unless I get some more options from this site I am going to set it on fire next!
At this point I have replace everything that actually moves in the entire front end.

Please tell me that you are not replacing stabilizer bars, but stabilizer links.
Replacing bars would be the total waste of $$.

Did anyone check your engine mounts?

I purchased 2 new rear stabilizer bushings & had my local mechanic install them today but I'm still having steering wheel vibrations! I was told my upper engine mount needs to be replaced so maybe that is causing the vibrations?
