I have a 93 Explorer with 150K on the clock.It has been a good rig,
but I have developed a problem recently.When I take off from a stop
(especially in a turn) I get a rubling noise.This happens only during
the initial aceleration.The motor and trans are fine.The problem only
happens when I have been driving for awhile.I had the rear end rebuilt
a couple years back and I suspect this could be the problem.I do all
of my own maintenence (With this exeption, guess it serves me
right).The car is a 2 wheel drive.Has anyone experienced this?
So whats yer axle code?
If you have a limited slip, it could be the friction material in the discs
has erroded away and now its time for replacement.
If you have an open diff, then it could be the spider gears and side gears
are worn from lack of lubricant because one tire is spinning faster than the
other constantly (two different sized tires on the same axle). It could also
possibly be a cracked or broken spider gear causing undue torque on the
other gear causing the noise..
Just my $0.02
Dear Ford Tech,
Thanks for the resonse.Where is the axle code?Both tires are the same
size.Is there any way to verify this stuff about the spider gears
without a tear down?If I did need to replace these gears, what would
be the best course of action, Junkyard?Or are there Ford or
aftermarket parts that would do it.Thanks
Axle code is a two digit code on your certification label on the drivers
door pillar. Its in the very bottom row, and has AX CODE above it. Its on pg
12 of the document below..
Should be an D something or 4 something code. D something is the code for
limited slip and 4 something is an open diff... Check out this website it
explains all the axle codes. Scroll down to middle of page.
Don't listen to the drivel posted by the Backyard Mechanic. He's a hack. ;)
That was a just a good natured poke at a fellow that I haven't seen here in a
Heed the advice. The friction modifier will likely work. Backyard is a smart
just don't let him know. It'll go to his head. ;)
Hey BY, where ya been? I haven't seen you post here in a while. I hope all is
with you and yours.
