a not so fun day at the track

well. the fun had to end sometime.

first pass. babied the car out of the hole, not shifting fast, went a 14.1 with a 2.0 60ft.

second pass. took it up to about 3300-3500 rpms, dropped the clutch, stood on it {trying to get a 13 second pass} SNAP! sheered a u-joint in about 50 pieces all over the track.

pulled the axle out, called a buddy who had a spare, swapped it out, no biggie.

did the burnout contest, everything was fine before this. then i go to go home after changin tires. anytime i turn the wheel sharp in either direction there is a loud clunking in the rear end. being that it didn't do this before the burn out contest. but now does it after? my thoughts are on the brakes are shot now. or broke a stub shaft, ooorrrrrr damaged a spider gear in the rear end.

before i left the track, i checked under the car, nothing was loose. im gonna pull the drums off tomorrow and check and see if there anything in there that is broken.

it's a thump that is loud enough to be heard, and felt clearly, and the car wants to jerk, and try and stop.

before i left the car didn't want to move, like ceased up brakes. so my theroy is i fried the rear brakes?

any thoughts?

oh, here is a pic
