    Exclamation 2 problems- Vibration from rear on hwy; Grinding in 4WD

    First off, I (proudly) drive a 2000 Chevy Z. I bought her used with about 65k on the clock, but she's runnin about 115k now. My problems rest with the drivetrain, somewhere. When I'm cruisin on the freeway, once I hit about 65mph, I start to feel a vibration possibly from the rear. It's constant and increases in severity with speed. I'm thinking that I might have a chipped/broken gear? The tranny shifts good and hard with minimal, if any slippage. Could it be the U-joint, or do yall think it's the gears?
    Secondly, when I actuate my 4wd I hear a grinding/whining sound coming from the front accompanied by a definate pull to the right. On another forum someone said it could be a CV shaft, but I've checked the boots and there isn't any leakage or wear/cracks. Thanks in advance... -Under

    ok #1 the vibration check the u-joints for any play in them.if its not that be ready to pop off the diff cover.now you said its a z which most all of them came with a lsd and not the open diff the lsd's are pretty much junk after 100k

    what youre hearing in the front end is probably the front diff motor which is a pretty easy thing to replace..have someone else put it 4wd with your head by the front diff youll hear it right in the center of the front diff

    Ricer: from the latin word Ricarius meaning to suck at everything you attempt

    A person who makes unnecessary modifications to their most often import car (hence the term "rice") to make it (mostly make it look) faster. The most common modifications are (but not limited to):

    - Huge exhaust that serves no purpose but to make the car louder
    - Large spoiler on the back that looks like something Boeing made for the 747
    - Lots of after-market company stickers they don't have parts from, but must be cool
    - Expensive rims that usually cost more than the car itself
    - Body kit to make the car appear lower, usually accented with chicken wire
    - Clear tail lights and corner signals
    - A "performance intake"- a tube that feeds cold air to their engine usually located in areas of excessive heat (behind or on top of the engine)
    - Most of these riced cars (a.k.a. rice rockets or rice burners) are imports; Honda Civics, Accords, Integras, CRXs, RSXs, Del Sols Mitsubishi Eclipses, Lancers, Subaru Imprezas, however there are some domestics such as Chevrolet Caviliers, Dodge Neons, Ford Focus; small, slow, economy cars designed specifically to go slow. Please note that some 3000gt's Supras, Skylines, WRX's and other higher performance imports are designed to go fast, and are therefore not always considered rice, but it really depends on the severity of the case.

    Sweet, thanks for the quick reply. How hard is it to replace the limited slip? Special tools?

    i got mine from a local speed shop for i think it was 525ish with the new bearings but thats because it was my shop truck at the time and it needed to get fixed fast.

    but really check the u-joints and what not first..depending on how hard its been driven your vibration could also be the ring and pinion or just the pinion bearing,could even be wheel bearings its hard to dg something online but i do my best without having it right here in front of me

    Thankfully I won't have to drive to and from work since I'll be living on site. I'll check the U-joint, though for some reason I don't think that's the problem. I hope it is, cuz at the moment, I doin't have the cash to drop on a new diff.
