You prob can but it wouldnt be fun at all. Best just to pull the engine out. What's wrong with your crank?

Pull the engine, if you have to change the crank you likely need other work.

Sorry for the late post. Where or from who can I get a good quality Crankshaft?

Interested minds need to know, what is wrong with your crank?

 

[obwhan]

well FWD and AFT movement of the crank and I keep tearing up the front seal on my trany. on the 4 seal. second trany, second torque converter, rebalanced drive line. and second flex plate. got 185K on the truck.

Sounds more like a thrust bearing required more than a crank.
Just how much crank movement (end float) do you have? Dial gauge on the crank and max movement either way?
But pretty hard for an auto to destroy a thrust washer unless there were problems with the flexplate/torque converter earlier in it's life.
