Help diagnosing the mystery noise

acura
legend

#1

It sounds as though the right front tire is constantly going over the road bumps that sit in between lanes on the freeway, however, there are a number of caveats. The sound only begins to occur about 10 minutes into my ride to work and only when I have my foot on the gas pedal at speeds over 50-60mph.



I recently got 2 new front tires and thought it might be a balance problem but that has been checked and the bumping sound remains. Could it be an engine problem or is it more likely to be an issue with the tires/alignment? This is a 1992 Acura Legend with 190,000 miles on it.



Any advice would be much appreciated! Thank you!

Did the noise start when you had the new tires installed? If so, you got a bad tire. To confirm this, switch the front tires and see if the sound moves.

If this was occurring before you got the new tires, then are there any other noises, like a clicking sound on corners? That would be CV joints.

If not that, then, when it is safe to do so, swerve mildly from side to side when it is making the noise and see if the noise changes. That would indicate a wheel bearing.

Keith, The noise did start when the tires were installed so I suspect it has something to do with that. I haven’t tried switching the front tires though. I’ll give that a go and if it doesn’t work try the quick swerve.

Thanks for your help!
