(sigh) again no year .make. or model. ok most likely cause is you have a limited slip rear differential and while turning the inside wheel travels less than the outside, the sound and or feeling you are experiencing is the rear diff trying to keep both tires turning at the same rate. The pop is the clutches releasing. might want to get the gear fluid replaced asap.
Broken Shock or spring seat or body mount.
It could still be a bad CV joint.
You have a feeling of going up sharply and your eardrums 'pop'
Remove the brake drum. Take a hammer and smack the stud you want to replace sharply on top of the threaded area and it should pop out the back.

They don't
When the diff lock sticks make sure the diff lock lever is able to move freely. If so drive the tractor in 2nd gear with medium rpms. Sharply hit the brake while slightly turning the steering wheel and NOT touching the clutch. It might take a few times but the diff lock should pop out.
the reson it is turning 90 degrees is that you are not getting a proper flick after the pop or it could be that your foot is in a pop shuv it position :/ i hope that helps :)
You have to pop the rear seat out and there it will be.
FIRST BLOCK THE REAR WHEELS SO IT DON'T ROLL WHEN YOU REMOVE THE DRIVESHAFT. Then take a screw driver and pop the rear seal out of the transmission tail shaft housing and then tap the new seal in with a hammer being carefull not to bend the seal.
pop the wheels off, un-do the 2 x caliper bolts take caliper off take springs and shims off the original break pads as they might be needed for the new set.. refit and done
