went to the track tonight and i launched hard and it gripped pretty violenty..so i finish out the run and get back to the pits.... i put the car in 1st and start to move til about 10mph,
then de-celerate to come to a stop and its making a loud whining sound.. the same sound you would hear if you went in reverse really fast.

it only does this in first gear.

anyone know what this is?

i ran a 12.3 .499 RT, 1.8 60', 114 trap speed.
the second run i came out of the hole sideways spinning all the tires and that left me with a 12.9

 

Transfer Case

 

is it on its way out?

do i need a new one?

how long do i have till it breaks? or if its broke?
