when i drive at 50 mph and up, it shake. what is wrong with it?

 

did you lose a weight on your wheel?

 

What have you done to it recently? Anything? Change tires? Wheels? Anything in the suspension?

If not, I'd get your wheels balanced and have your alignment checked. That's what I'd think first anyways.

 

yeah thats what i was thinking. i changed from original wheel to 18' last winter. more than 10k miles on it. ill check with it at tire store tomorrow then

 

yeah just a simple balancing, high speed maybe.

 

ditto. either that or you're usin' too much NOS :-DDDDDDDDD

 

how much does it cost to get it balanced?

 

well, I just saw this thread .... and looks like everyone beat me to it. You just need to balance your tires like everyone said. I had that problem on my camry a while back.

Shouldn't cost too much.

It should take a tire shop all of about 10-15minutes to take the front wheels off, balance them, and put 'em back on.

 

Im looking for the best place to put 10 inch subs? Kinda having a hard time with it...... I dont want my box to rattle...When i pull up next to a light,,,,,,

 

Most of the time the place you got them from will re-balance for free. Have them load balance them. It makes for a better balance job.

 

Maybe it's from wheel hop?

 

Where did this come from? how did we go from balancing tires to sub placement?

Maybe you are looking for the "ice & interior" section?

Take it to a tire shop. Noone here can tell you with any certainty what the problem is.

 

I am thinking kenny is a little slow

 

Get those Speakers BALANCED! damnit don't you people read!

 

LOL, word, it's either wheel hop or he's running low on blinker fluid. ^_^

 

I know bad muffler bearings are sometimes to blame also.

 

might want to check with the dealer on those bearings.... heard that there was a bad batch & the dealer was supposed to replace before car was sold..... oh wait ... my bad.. that was on the Hondas...

 

I replaced my stock muffler bearings with Offenhauser billet bearings, and am getting about 11% better mileage.

 

Either its your tire, or its the problem I had, the rubber boot on my front axle a while back came loose, and dried up the grease, so therefore my shaking was caused by my axle being f&^*ed up... And had to get a brand new front axle...
