AWD no more? Drivetrain woes

[4G63 For Me]

So I'm out tonight on some abandoned road and hit a red light. Nice. No cars coming, and I hit the light red. So I'm sitting there, and figure I'll launch the car (because it's fun). So I mash the gas, the RPM's stay at 6000, the boost builds to 10PSI and stops (gotta love 10PSI AWD launch ). I then launch on green, probably letting the clutch out a bit too fast, as I heard the tires chirp. Then a pop and a VERY sudden and brief loss of power (I'm talking fraction of a second). The car didn't feel the same after that. So I'm thinking perhaps something broke and I'm only putting the power to the ground via 2 wheels. Either that or my car backfired. Well, I pull up to another stop, and I have to make a left turn. Perfect. I'll launch again. Sure enough, the tires spin (not unusual when I launch on a turn, even with AWD), but the back end slides out like a mofo. I let off the gas at that point. Weird, I thought. So I stop. Launch the car again and the tires hold, but the car shudders a few times (not the engine or turbo, the differential). So I stop again. Launch again. FELT like normal AWD.

I suppose my question is this: how do you know when something broke and you aren't running AWD anymore? I have pretty wide tires on all around, so perhaps I'm just not making enough power to spin even two of them that much. So.. how do you know?

Also, my apologies if this is in the wrong forum. Feel free to move it to the appropriate forum.

CONCLUSION: "If it doesnt break the first time, Im going to keep trying till something does"............zeesh :thumbdown If it didnt feel right the first time why would you keep doing it??? Anyway, im going to answere your question in the manner you asked it.

It either wont move, feel noticably slugglish, or 2 wheels will start to break loose at WOT

Is there a way to tell visibly? Or "mechanically"?

I kept doing it to gather more information to hopefully come to a conclusion. However, I lack the knowledge to determine that, so I'm asking here in hopes someone will know. Should I just never launch the car again if it acts weird once? That'd be silly. I've never been in a two-wheel drive car that was capable of breaking the wheels loose, so I'm not sure how different it would feel. I appreciate the response, though.

I hope you never park in front of a wall.

Eh ####in wiseass...

Anyway. Put the car up on 4 jackstands and put it in gear. Take her up to 120 or so. Or hell even do a launch on the stands.

Ahh, excellent idea, Roast Beef!! Thanks, man!

Yeah, I missed Defiant's joke as well. However, his comments are usually pretty darn hilarious :laugh:

My guess is you broke an axle, 90% of the time it will be the rear-driveside tire. which will break INSIDE the diff. IF that the case, put it on stands and spin each tire with the car in Neutral. when one thr front turns the back shouldn't but the opposite front tire should move the opposite direction. The rear tires should make all 4 tires turn. Check this befor you go breaking your car any more.

Hope this helps

my buddy out here had a problem like yours but it got worse over a short period of time. It was the front differential in his tranny that let loose, he was RWD for a few days till it wouldnt move anymore. BTW its more common for front diffs to break on FWD's but it happened to me and my friend with out AWD's within 3 weeks, so go figure. Is it making any grinding noises or is it fighting ur engine when u accelerate?

 

[4G63 For Me]

No grinding, no acceleration issues. It seems to be AWD still. Perhaps it was only a backfire and I'm just paranoid. When I get some time off from working 80 hours a week so I have money to dump into this thing, I'll put it up on stands and see what the dealio is.

Thanks for all the responses and suggestions! Long live

 

[laserspeeddemon]

when my axle went out, it made no grinding noise at all, however, the car could not acclerate for sh*t.

Well, you seemed to keep trying to exterminate your driveline until you succeeded, I could just see you ramming a city block until it was rubble.

I highly suggest re-evaluating the term "moderator".

"Well, you seemed to keep trying to exterminate your driveline until you succeeded, I could just see you ramming a city block until it was rubble. "

Actually, I don't think I've succeeded yet, but I'll keep trying. And I think the "bumper" would probably crap out on me before I managed to turn the city block into rubble.

Umm I don't think that is very good advise do you think that maybe the car might fall off the stands when he tries launching it? And going 120 on jack stands is not smart and is not going to help diagnose the problem.

:laugh: :laugh: Where's the smiley face of me driving my car off the stands and through the garage?! Here's the closest thing I could find:

Ha ha ha ha! Damn this shits funny sometimes.
