Here are some frequently asked questions about early broncos. If
you have comments and/or additions, contact Brett
Shankle. 1. Q: I want to put a suspension lift on my Bronco, What
other modifications will I need to make? A: The trick here is to go
with a complete "kit" when lifting, some items to look for are:
Avoid lifts of over 4" unless you are going for a totally
radical truck.
Lengthened or adjustable track arm, this keeps the front axle
centered under the truck.
Polyurethane front bushings, holds everything in place;
C-bushings should have a 4-6 degree offset this reduces the axle
from rolling forward ( to a point ).
Dual shock absorbers, front and rear.
Longer brake hoses
Use a well known company for parts, they will have a tech line
for you to call if you need help.
2. Q: My Bronco makes a noticeable "CLUNK" sound when I
accelerate from a stop, why? A: Most likely it is the spring
mounting pads on the rear axle, look to see if the mounting pads
are rounded off or bent, if they are, replace them or weld up and
grind off material until it is flat again
3. Q: When I apply the brakes, my Bronco makes a sudden
change of direction, not always the same direction, why? A: Check
the rubber bushing in the front suspension, look for missing, worn
or deteriorated bushings. If you find any that need replacing,
replace them all at the same time.
4. Q: No air blow out of the heater or defroster when I turn
it on, the fan motor is turning. A: Look into the passenger side
air intake, right in front of the windshield under the hood, and
follow the duct-work to the fan, look for a build-up of leaves or
any thing blocking the air-flow.
5. Q: My Bronco has vacuum operated wipers, every time I
step on the gas they come to a stop, why? A: Some one has removed
the original fuel pump which had a vacuum pump on it, replace the
pump with the correct type or as a temporary fix, put a vacuum
reservoir in the system.
6. Q: I want to replace the 6 cyl. engine with a V-8, what
is a good choice? A: Any of the small block ( 289, 302, 351 )
motors are a good choice, a big block motor can be put in, but, it
is way heavier and much larger. There are plenty of kits to swap in
small blocks
7. Q: What tire size can I run on my Bronco? A: Depends,
33x12.50x15 will fit with cut fenders and no lift. Uncut fenders
really limit the width of the tire you can run. A lift kit allows
much larger possibilities. Gear ratio is also a concern if you go
to monster tires.
8. Q: I want to go to a 4-speed transmission, what is a good
choice? A: Once again, depends on the use of the truck. The Ford
top-loader is the usual choice, It is easy to find and get parts
for and several companies make adapter kits to install it
9. Q: The front of my Bronco seems to sag, what causes this?
A: Three things to check:
