Gears & Axles - Busted rear or no?

I did some heavy accelation on crappy/old/cracked/destroyed pavement, under nitrous...

Right after it, there is a loud tok/tok noise when decelarating coming from under the shifter (vibration). The car can accelerate fine(I can feel some vibrations still) and cruise around 1800rpm without too much problem, but that sound comes back hard, like if it was coming from the driving shaft to the tranny.

Anyway, sounds like a busted rear end to me.

Last time I had a similar vibration/sound, it was the clutch..but now the car aint fine under normal acceleration. Cant believe my Monster stage 3 clutch is done after only street driving..

I checked under the car, nothing seems loose..

you couldve broke a trans mount or ujoint.




if your rear is broke itll let you. trust me. itll be noisy.

torque arm?

It sounds more like you broke the transmission mount or the troque arm mount. If it's the transmission mount I would think the tranny would be hitting the floorboard when you kick it though. Thats what mine did when I broke it. If its the rearend you'll know. If you broke the gears they would start clunking and wining VERY loud at speed. If you broke the diff it would kick around some while turning, almost acting like its got a spool in it.

Yeah, I thought it sounded like a trans mount cause it sounded like something was hitting the floor or the frame around the trans, almost like a banging exhaust..It's really weird. I'll try to jack the car high enough to have a good look under.

**Under load, the sound is almost non existent BTW**

I took a good look and nothing is cracked/broken under the car; trans support, torq arm support, U-Joints, torq arm bolts, etc..

The thing I noticed is this Y pipe support broken!? Could it be the Y pipe beeing loose banging and rubbing around??

**THE SOUND IS WAY WORST WHEN GOING SLOWER THAN 10-15MPH. COULD IT BE U JOINTS GONE BAD!??**

How to tell U joint is bad visually?
