hey guys well I have a problem... I just got my B13 aligned because it was pulling to the left ( they had to put in a camber bolt and all that good jazz) but anyways.. now my car is nice and straight.... only when I am off the gas...
......when I step on the gas it still wants to pull left..

so there inlays the problem. why is it doin this? Again it goes straight when I am not on the gas, but the minute I step on the pedal it pulls to the left pretty hard.....

Is it a half-shaft or maybe my tires... please help.. I hate having this problem,,,,,

thanks in advance

If they did your aligment they would have told you if there was something wrong/loose with the suspension...assuming the mechanics were competent...

In my opinion I'd go with a worn out diffirential...
Do a burnout... see if you can get the left tire spinning...
I am assuming it is pulling to the left because the right tire is pulling but the left one is not...

If you are doing right side uni's although you should be doing left ones (for example taking a hard left...) that might be it...

I'd recommend a big empty and preferably WET (very...) parking lot... ...so you don't have to buy new tires/transmission/clutch after doing the "testing"...:p

...it's a shot in the dark...but that's what I'd do first...

The other thing maybe a bent frame...but if they didn't tell you that at the shop...it should be fine.

When they did my aligment the manager nicely told me that the back right wheel is out of aligment...and they can't adjust it any father because of factory specs. And I will need to go to a shop with a frame machine.... The way he made it sound was like it was a $60 job. It's not...I'd be better off buying a new SENTRA... Considering I got this one for $800 I'll live with it...
What I'm getting at though, is that my SENTRA handles fine even with a not so perfect frame... So your car would have to be out of whack big time to do crap like that...:p

Good Luck...

Competent is the key word here.

Lastly, do you know how a differential works? Tell me how a differential problem would cause only one side to have power transmitted to it.

I'm not sure how a diffirential works...but I know that a worn out diff will cause those kinds of problems. ...this is from experience... Although Mustangs have POS I'd think that the same would apply to any other car....

I'm not saying the other side is not pulling...I'm just suggesting that it would only pull sometimes...hence causeing the car to swerve...
I am also assuming he'd know if he had broken motor mount or suspension problems...

But like you said Probedude...competent IS the key word here...:p

Ah, this is the difference. RWD cars without posi but with solid rear axles will under acceleration unload the right wheel causing it to break loose first. FWD cars don't suffer from this, but they do suffer from torque steer.

Since the SER has equal length driveshafts, torque steer is not as great but still there. If both front tires are the same type, size, and wear condition, I would suspect bad motor mounts, bad suspension parts or bad cv joints. Check the motor mounts first, they're sure to be toast on a 94'. Rotate your tires front to back and see if that changes anything. Check that your air pressures are the same too.

Well I got told...:eek:

It's all good though...you learn something new everyday...:D

I'll be the first to admit I don't know as much about FWD (read: Import...) cars as I do about RWD (Read: Mustangs...)...

That's why I'm here though....:p

Ahhh...the differential...

well, the differential is a very complicated thing. we all know that. your sentra has what we call an open differential. that is, the engine pours the power to the transmission, and from there it goes where it likes (read: the path of least resistance). if while taking a hard left you put the throttle on the floor, the inside wheel (left) would spin. but the outside wheel (right) would not, because it is easier for the engine to spin the left wheel, as it has considerably less traction, or resistance.

if your car pulls while accelerating, but not while decelarating, your transmission mounts are more than likely broken. this would allow the transmission to move. i would have them checked, also, sometimes the fluid in the cv joints can leak out, but this would mean you should hear a clicking noise, and it would pull while accelerating and decelerating. it might also be the brakes, like maybe a locked or seized caliper. while accelerating, the force might be enough to overcome the braking force. im sure there are other things it could be too.

how much power do you have....????

you have two different size drive axels on most ff imports, maybe ur putting power to the ground and it just pulling different casue of a short drive axel, im sure that not the reason but just saying...maybe ur tires are differnet sizes, if you can....burn the tires...have to ppl watch to see which spins which doesnt how much spoke they put off would be one way you could check urself...it would seem as if the left tire is not spinning or spinning as much...you will find a way to fix it
im sure of it(hopefullly that way wont be to stop hitting the gas)
