Is a shop trying to shaft me?

Had to put the yota in the shop for some drive line leaks... Driver side cv shaft and output shaft to front diff off the transfer case. The mechanic said he had to uninstall whole transfer case and install the oil seals. Is this normal procedure??? if so what about cv shaft?

 

It could be leaking where the Trans case bolts to the Trans in that scenario it would have to be removed and resealed with silicone. But if it's just a seal I dont see why the case would need to come out

 

its leaking right behind where the u-joint is connected to the transfer case.. yoke.. spline.. output shaft.. not up to date on correct terminology

 

front companion flange to be specific

 

Do you have any pics?

 

sadly no its in NE texas.. im down south

 

the bottom shaft...
