I took a video this afternoon to see if anyone knows what is causing this sound. I have a dull roar at MPH above 35-ish. Tires? Bearing? Axle? Front? Rear?, right?, left? I determined that coasting gave me the best chance at recording the sound. So I found a hill and turned the video on.
At 30 seconds I top a hill then take a significant left hand curve and the roar goes away. Listen a couple times to confirm. Has anyone fixed this before? How can I trouble shoot something like this? In the video I assume that it is front since it goes away. Good assumption or not? This car/engine, etc... has 4400 miles on it... old tires, old tranny, new front bearings and bushings, a new right hand axle (both CV joints from Tangerine Racing). alignment all round. I guess the sound showed up a week or so back, best I can remember. Just last week I finished sound proofing and new carpet, so it is a bit easier to hear. https://www.youtube.com/watch?v=kaGpgxC4iR4 |

Maybe the "bushings" threw me off. I thought of suspension, not wheel bearings. I've also seen low miles failures when cheap bearings were used, and there's a LOT of those out there. Takes only a couple of minutes to check 'em.

Takes only a couple of minutes to check 'em. The Cap'n As mentioned above, the sound is like mud tires on one side. (IMG:style_emoticons/default/confused24.gif) Hell, all the bearings have been done... with exception of the large rear ones in the control arms. I suppose something could have happened to the right rear wheel bearing when I did the axle. I did not take it out, but maybe should have. I'll have to dig up the receipts to see what brand and quality I used. Of course, I am driving, so I am on the left side and I can, with some difficulty, stick my head out of the left window. I hear nothing. I suppose I should let someone else drive and stick my head out the right window. (IMG:style_emoticons/default/hissyfit.gif) I really hear nothing on the left. I'll check them all. Breaking out the jack stands, I guess. (IMG:style_emoticons/default/mad.gif) |
