hey guys ive been haveing this problem off and on and i dont kno what it is, sometimes when iam driveing the car seems to rumble like my tires are bad but when i stop and go agian its fine it only happens when i shift at 3k rpms but if i shift at 2.5k its fine all the way to 80+ mph

could be your pressure plate of throw out bearing going out. but that sounds like a weird problem.

Check your differential oil, and transmission oil. Those are the easy things.

Next, try pulling the inspection plate from the transmission, and look for loose PP bolts, etc...

Does it happen when applying the brakes?

thanks ill check the fluids to make shur, when brakeing it dosent rumble only when iam driveing but like i said its a off and on thing one min ill be fine the next it will be shakeing like a earthquake, could it be something wrong with my suspension or my tranny(owner before me just put a new clutch in)

did he put the stock clutch in or aftermarket?

he told me that is was just a new stock clutch that he bought from Advance auto stores

you should ask him who did the work. mabey they did something wrong when installing it.

he told me that he did it him self and he said he did everything right so i dont kno do u guys think i should got get a new one and get it done at a shop, iam alot thinking it might be my drive shaft it might be loose or some thing

drive shaft would make noise at highway speeds not just at a certain rpm. bring it to a tranny shop and have them look at it thats my advise.

thanks will do

Specifically, the carrier bearing in the middle of the front and rear shafts.

kk thanks
