I am having the same problem with my truck pulling HARD to the left in second and third. Has anyone else run into something like this? I have read about people taking apart the center diff and putting in some lube and the rear diffs and putting in some lube. Can you explain a little bit more about this? And also where should I put some dry ice lube? I am getting confused reading all of this on where to put all this differant lube. Also, where do you buy 50000 wt lube and dry ice lube? Thanks!
