I recently purchased a used 2005 RL with 94K miles on it. Everything seemed fine when I test drove it but apparently I didn't look at it well enough. I am feeling a vibration (and some noise) while traveling over 60 MPH. It seems like the vibration/noise is coming from the rear of the car but I really cannot tell. I like everything about it except the vibration. Does anyone have any tips to help me figure out where its coming from? Seems like it could be coming from different places. I don't know if it is going to help but I am going to replace the tires. wondering if there is a balance problem that could be contributing to the vibration. I believe the tires have about 50K miles on them.

Any help is appreciated. Thanks!

 

rotate tires and see what happens. 50K on tires? they are prolly noisy and due to be replaced

 

Most likely it is a balancing issue. I will suggest getting a Hunter Roadforce balance when you replace the tires. I had one done and it fixed the minimal vibrations I was getting around 65mph.

 

...bent rim?

 

I had a slight vibration above 75mph ... Noticed it after having brand new tires put on. I had them re-balance the wheels/tires (Roadforce), but it turned out to be a slightly bent rim, so slight, that when balanced, it was still in spec. Moving the rim to the rear alleviated the vibration I felt ... Just need to get the wheel fixed now. Anyway, I would also check the rims themselves.

 

Thanks for the advice, fellas. I haven't heard of a "Hunter Roadforce" balance before. I'll look into that. I'm just hoping its not the transmission or other expensive-to-fix part. I plan on getting new tires in the next month or so. I can live with the vibration until then. If it doesn't get better after I change tires, I'll post back.
