Asked by Jan 21, 2016 at 01:19 PM about the 2003 Ford F-150 XL 4WD SB

Question type: Maintenance & Repair

I tried using my 4 wheel drive to pull my boat
trailer out of the water and the rear tires just dug
trenches!  I was Po'd because I took to a mechanic
and he said to put in 4 wheel drive so I turned knob
to 4 wheel high and the indicator came on and he
had me put it in reverse and he said it was working
because the differentials were fighting each other
in reverse but when I go forward nothing?  Any
suggestions?  They are talking at the shop they
need to open up the transfer case?  Wonder if it is
vacuum related?

Your mechanic sounds like he is giving you BS. The differentials don't "fight" each other in reverse or going forward if you are driving in a straight line. Curves yes, straight no.

He told me to turn the wheel and put in reverse and I noticed it was fighting each other as he put it!
