I purchased a 2004 Wolverine with a detroit locker in the front diff and a Warn unlocker on the front drive shaft.
When I put the unlocker into 4x4 the thing steers to the left uncontrollably. What would cause this?

 

you must be reffering to the Wolverine. the warrior never ever had four wheel drive. Most of the reviews i have read about wolverines and aftermarket lockers have not been success stories. I wish i could be more help. You may also want to try woodwarrior.com there are some guy's who have done it over there.

later.

 

Yes I meant Wolverine, my bad I used to have a Warrior.
Thanks for the info.
