Q: Transfer case isues

asked by on

So when my truck is in 4x4 and i accelarate there is a vibration that feels like its comming from the middle of the vehicle and the harder i accelarate the stronger it becomes, ive also noticed it has some dificulty shifting in and out of 4 lock so i have to keep switching back and forth for it to switch. Now i do know my tires are off ballance so i dont know if that would be a contributing factor to this situation

My car has 100000 miles.
My car has an automatic transmission.

Hi there. The vibration in the middle of your vehicle upon acceleration and trouble shifting in and out of 4 wheel drive may be a bad transmission mount. If the transmission mount is broken or sagging, the driveline angle changes and results in vibration. This could also affect the shift linkage. Tire balance could be a contributing factor to the vibration felt. I recommend having your vehicle’s vibration upon acceleration and difficulty shifting diagnosed and repaired by a certified technician, such as one from YourMechanic.
