I would think Dodge would have a lock nut ID number on file by your Vin number. The lock number for mine was listed with my papers when I bought my truck. (I would assume you have checked at your jack and your lug wrench pack For the key)
My 09 (2 wd) had a vibration in the steering wheel, they replaced both front wheel bearings before 8K.
It's my truck and I want it the way I want it!
IF YOU DON'T HAVE TIME TO DO IT RIGHT, WHEN WILL YOU FIND TIME TO DO IT OVER??
