noise after 17x9s The second that i put my GM ZR1 wheels on (17x9) it started making all kinds of noise. At first it just sounded like tire noise, but after about a hundred miles on the road it sounded like a problem. I sold the stock wheels. These wheels balanced out fine. At about 35 i get a whoop whoop whoop sound from i think the front, but all the time, even at a half mile an hour i get a sound from the rear end that sounds like bearings. Is this just a strange cooincidince? could the noise from the front just be rear end noise being transfered up the DS? Its still smooth. Did i maybe put the wheels on too tight (100lb/ft)? I have new rotors and pads to put on soon.
Any help would be great!

The "whoop whoop whoop" sound I had recently turned out to be pinion bearings in the diff, but there was no mistaking where that noise was coming from. And uh, it was really loud too. It echoed off of other cars.

Since the only thing you changed was wheels/tires I'd guess something isn't right with them. I did the exact same swap that you did (Z28 16X8s to ZR1 17X9s) and that did not increase road noise nor cause any other noise at all.

I dont think its the tires because the noise seems to have gotten worse, plus its way too loud for tire noise. It starts out like a roar even at a half mph. The noise is coming from the rear for sure. It sounds like the carrier bearings or the pinion bearings. Could the noise from the front be coming from the rear up the driveshaft? It does it at about 35mph. I was planning on getting a moser 9" to fix the rear end problems. Hopefully it will fix it. If not then i know what the problem isnt. The tires are Falkens. Im not happy with them at all b/c they dont hook up at ALL.

What sucks is now that the rear is setup properly, pinion depth and new bearings and such, the gear noise from my 3.73's is a lot more apparent. Doesn't really bother me much since there's technically nothing wrong. Some people get whine from aftermarket gears, some don't. Trending Topics

See, if it was gear noise from a swap then i could handle that easily. Thats the sound of an improvement. Mine still makes noise in reverse too. Its getting on my nerves. I dont really want to drop all the $ for a 9" right now. I kinda want to just throw a set of 4.10s in the 10 bolt that i have now. I've got a MAC cover that i could use, but i just dont know how long that thing would last. If i did polish the terd (10 bolt) then i would NOT take it to the track. I would most likely drive it until it was paid off and out of college. Then get my 9". It would be a cheaper way to figure out if it was the rear end or not.

I'm having the same problem...so what was the solution? Did you have to change the carrier bearings or pinion bearings? Or wheel hub bearings? I'm probably gonna take my car to a reputable shop next week.

I think thats what i am going to do. So the 10 bolts only fail from High RPM drops? B/c i never drop mine. I am much more fond of the "2500 rpms then nail it to felony speeds" kinda driving. Interstate ramps are my fav! But around town i am a 1st-3rd-5th driver. Since i put these wheels on i dont even do burn outs any more.

Well, to be honest i cant get my 275s to hook up at all. first gear is useless anytime in full throttle, and when i hit 2nd i have to let off or it wont stop spinning. Falken tires must suck! My old goodyear 16s werent even z rated and they hook up better than these.
