i don't know of any specific applications that are made for the f-150, but
have you thought of building your own box? all you need is the dimensions
from the box you saw in the crutchfield catalog (incl. port size if ported,
etc...) and some MDF. with a little elbow grease, building a sub box is not
as hard as some think. I built one for my 96 ranger sc which houses four
mtx 8in. subs. it sounds and looks great. as far as your amp goes, if you
were only running one sub, you wouldn't need a huge amp to power it. you
could use a smaller amp and bridge it to bring the load level to
which would increase your power without sacrificing sound quality (which
isn't THAT significant if you're running your sub 80 ohms or less). hope
this helps.

i am glad that everyone had their fun with my question about lowering my
f-150 4x4. thanks to those that e-mailed me directly with your advice - i
am still working on it. as far as the rest of you that questioned my
reasoning for lowering my ride, the answer is this - because it's my truck
and i want to. i believe my previous question was seeking answers from
those who have had experience or knowledge of the difficulty in lowering a
4x4 - not for anyone's personal opinion on whether or not i should do it.
so, once again, i will pose this question - does anyone know where i can
find TECHNICAL info. about lowering a 4x4 without sacrificing the truck's
inherent abilities?

This is my first post. Hope I did it right!! I'm planning to purchase
a SD PSD and have learned a lot from this group. Thanks everyone.

There seems to be a solution regarding the air expansion tube
(vent) from the differential. What would happen if the tube were lengthened and a
small, PROTECTED rubber balloon (or something similar were placed over the end.
This would allow for expansion
and still keep out any water, dust, ect. Considering the volume of the differential
the balloon device wouldn't have to be all that big, I wouldn't think. Try to keep
the elasticity of the balloon device such that there is little pressure build up, so
the internal deferential pressure stays low. A little experimenting would solve
that question quickly. What do you think?

I'm guessing the pressurization effect is because the differential is hot from
turning. So if you are driving and stop in water, the differential will rapidly
cool producing suction. Where as if you keep moving in deep water you are
producing enough heat to keep a suctioning effect from starting and with out
suction the water cannot make it up the bend in the hose. So it's not really
pressurizing but that describes it good enough.

I think that you may have come up with something. Maybe you should contact
the manufacturers, but maybe this problem that we all are discussing really
isn't as bad as we all think. It seems that the industry would have thought
of that already if there really was a bad problem with water in the rearends
and the like. You would think that some one working at an aftermarket 4x4
shop would have solved this problem. Sounds like a good way to make a few
Bucks!
This is a great place on the net and by the way.....I am still driving my

I have seen very little about lowering a 4x4. I mostly see lowering on 4x2. At
my dealer a while back a guy was at the service desk asking the same question
and the handed him a pamphlet from an aftermarket company and said you would
have to go through them. Know I don't know if there was a product for it in
there but its worth a shot.

Ya know all of that sounds like it would work but this is what I would do.
1.) Cut the tubing back a bit (not into the bend)
2.) Go get a check valve that will fit in the tube
3.) place in line. That will alow breathing because check valves only orerate when there
is high suction so air can get in slowly but if you go in water and suction happens it
will blockit. Most auto stores have check valves that operate on various pressures.
Just what I would look at doing.

Scott and Lisa,

Ignore the others, there's nothing wrong with wanting to lower your 4x4.
In fact, companies such as Belltech are starting to make kits that
"properly" lower 4x4 trucks and SUV's. They have a new 4x4 lowering kit on
there website (www.belltechcorp.com, go to "What's New") that lowers GM
trucks 1 to 5 inches. I didn't see a kit listed for Ford, but I am sure it
is available. They have a lowered 4x4 F150 Flareside pictured on there
website. I would drop them an e-mail. I hope this helps.

Subject: re:FTE 97up - Putting a subwoofer in a 97 F150 Ext Cab

My best suggestion if you are looking to do what you want for that
kind of money is too find a decent sub and buy it and get some 3/4"
press board and make yourself a box. This should run you about
$100-$150. As for getting an amp, if you are not too picky, there is
always Radio Shack, or another possiblility is a pawn shop. But, amps
don't come cheap unless you don't care about the sound.
P.S. the amp will need to have line in connections, hard to find. You
may need to get an adapter to get you back to RCA connections.

Wish you luck

You actually answered your own questions at the end of your post.

When the differential is assembled, it contains air and lube. When the gears
turn, everything heats up including the air which expands and has to be
vented. Perhaps "pressurized" was not the best term but I was trying to keep
my answer simple and short. Anyway, when the differential cools, air is sucked
back in. So, if you are running through water at a reasonable speed and the
end of the vent tube goes under, the pressure difference plus the bend in the
tube will usually be enough to keep water out. However, if you stop of get
stuck in the water, the differential will cool off quickly and suck in water
big time.

This is a common solution used by fourwheelers that do a lot of deep water
crossings and mud running. I have never tried it, but from what I read, it
works pretty well.

OK do what you want, but one of a 4x4's inherent abilities is ground
clearance. Lowering it will reduce this inherent ability, in fact, you will
be putting your vehicle in more ..... ah screw it, its just a dumb idea,
unless you had an all-wheel drive not a 4x4, then I might just maybe
understand.

OK Guys,

Why couldn't a guy use a long run of vacuum line or whatever and run
it over and up or back and up somewhere high in the bed structure: Up
the rear wheelwell as high as you can go, or up between the double
wall somewhere.
The farther forward the better as far as boat launching goes also.
The extreme would be to run it up between the cab and the bed so the
end is near the top of the bed. If you get in water that
high........well you shouldn't be treating a Ford like that ;-)

My $.02 worth..........
