Nope...shops will not rebuild our front shafts. Several have checked into it including myself. Has to do with the type of joint our shaft has. A used replacement from a recycler will run $50-250 depending on the place and mileage (i paid under $65the shipped for mine).
The job is very easy and straight forward...I believe there are 8 8mm allen head bolts on each of the flanges (front and rear). Might take a little force to get it out and then just slide the replacement in and put the bolts back in.
