k lets get straight to the point, i put my car up on jack stands to see if my car has lsd, when i rotated my right wheel and the left one did not move an inch at all. do i have a broken lsd or messed up open diff? i know when u rotate a wheel on open-diff the other rotates in the oposite direction, and the lsd rotates at the same time. is it broken or somthing else... i dunno?

 

It could just be worn to the point of not "limiting" slip any more. Was the car in gear when you tried this? If the driveshaft was turning I don't know if the other wheel would turn opposite.

 

well it was'nt in gear, and forgot to say this but when im driving once i let off the gas it starts to make a clunkity noise also it goes away when i press on the brakes. it sounds like somthing it flopping around. the noise seems to be comming from the rear left wheel.

 

Investigate the problem more before you drive it. I'm no diff. guru, but maybe a worn out spider gear, or completely killed CV joint.

 

Sounds like a tired lsd. Open Diff is when tires spin in opposite directions, Limited Slip is both spinning one direction (But not always 100% accurate), Tired lsd is when 1 spins one direction and the other doesn't move at all.

yeah its worn out. the clutch packs dont have enough friction to even overcome the weight of the wheel. itll still get you down the road just fine, but it will have no LSD protperties.

 

A normal open diff if the tranny is in neutral will not turn both wheels if it can turn the transmission it will just turn that. To make sure it's a tired lsd put the car in gear when you turn the wheel and make sure the other wheel doesn't turn in the opposite direction.

Check out the noise, could be the axle joints I suppose... it could be anything though, even your driveshaft hitting a heat shield... believe me, I've had that happen too many times to laugh about it... clank noise I always check the heat shield first.

i might be stating the obvious but, ... is your car an SE model?

SE = no LSD

 

well my buddies told me it was a gxl but im not sure. all i know is that i dont have a sunroof or power windows. and i got the gay small spoiler thats made of foam.

 

I'd suspect a CV joint with the clankity sound from one side. Or a spider gear is floating around inside your diff housing It will work its way out eventually, maybe through the aluminum part of the housing! I had a Chevy 10 bolt rear come apart on a car, it looked like a grenade went off inside the rear end, holes everywhere. Have you looked at the rubber CV boot? Is it intact? A rip will give you a good clue that the grease is washed out.

 

ill check it when i get off work, on a totaly different subject, is it safe to run a car without a thermostat? some ppl says its better and some say that im going to mess somthing up

 

does it have 4 piston front calipers and 5 lug wheels? if not then it isn't a GXL and thus has an open diff.

as Bob said, with a manual tranny in neutral it will spin the driveshaft not the other wheel since it takes less force to turn the tranny than the other wheel. even a tired posi diff will usually overcome the force of turning the driveshaft when it is in neutral so i am most positive you have an open diff.

check all your susp components and u-joints and CV joints for the clattering.

 

i have the four lug so its open diff then. aww i wish it was lsd
