i broke like 7 passenger axles already

so ok today it broke off and this time i coudlnt even drive the car


from the past when i went to LA

i was hitting 4th gear and it suddenly pops and my steering gets hella hard to counter/control...

then it would clunk clunk clunk loudly until i stoped...so i changed a spare axle on the side of the road. The car drives fine now....
Then the same day as i was at the track...in 4th again and same **** happens
got a new axle and drives fine....

something has to be ******* up the axles!

im thinking motormounts/tranny mount right now
i also read a bad wheel bearing can damage outter joints

Could bad caster do it?
im at +1.9 FL
+1.4FR

anyhelp is appreicated..
