M5030su (model : 5030suMDT) 4x4 not working correctly. when 4x4 engage with leaver at left heel no spinning of both front wheels. If iI engage the front locker (with pedal at right heel) the front left wheel (i think) will spin and I also get a loud popping (both wheels will not spin). What is broke and how do I fix it? Thanks!

Will need your Serial number to give you more info as that model had 2 different locking front diffs.
The M5030DT I had used a Detroit type locker for the front. No pedal to engage. Auto locking.
Rear had a differential locking pedal.
Paint mark your front axle joints to make sure u-joints are not slipping on splines.

Are you saying that if you engage the linkage you get no pulling from the front end or you get them to lock with no slippage?
When the locker is engage is the only time i get pulling from the front end, only from one wheel.

4x4 engage no pulling from front end.
4x4 with locker engage pulling from front only one wheel. with loud popping noise.

Sounds like you need to get the WSM (aka service manual) and jump into it and find out what has let loose or worn out.
Most 4x4 with lockers has a weak link in the driveline somewhere to prevent damage to more expensive parts. If this is the case with orange tractors maybe someone already experience this issue and know what the weak link is. Without a little insight (I'm guessing) start at the front right hub and work back till I find a broke part.
