Just got the truck back (again) from another troubleshooting of the oil leaking outta this reman engine. They had to pull the engine to reach the problem and the mech said he found the 4wheel shifter had been put on backwards when he separated it from the tranny. It did shift very easily unlike when I first bought it, and after he put the engine in the first time; so am gonna check it for steering hop next chance and see if it's gone... Hope so.
