when i am driving with it in four low it pops out but if i hold it there it dosent have any problems with it. I dont have a body lift but i do have leaf sag which i think is the problem. any help is good
I've had this in an other vehicle of mine. The little springs that hold the gear shafts in place with a locking ball could be broken or worn. Due to fatigue, the tension of the spring isn't sufficient anymore to hold the locking ball in the slot of the shaft. Therefore if you just hold the lever manually in place, it doesn't pop out anymore.
Normally, if this is the cause, then there should be less resistance to put in low gear.
