Joint Spacer page]
-
Block the rear wheels and place the front end of the truck on jack
stands and remove the front wheels.
-
Remove the original ball joint hardware.
-
Knock the studs out of the ball joint with a small hammer.
-
This is done most easily if the joint is pressed against the arm
supported with a floor jack, as shown below.
-
Unbolt the upper shock hardware.
-
If you have greaseable ball joints, this is a good time to give them a
shot of lubrication.
-
Also, if needed, you can swap out an angled grease fitting for a
straight one to allow for later greasing.
 |
| Trimming around upper ball joint |
-
Trim the outer lip of the upper control arm (UCA) as depicted in the
above picture.
-
An angle grinder with a cut-off wheel or a small reciprocating saw
works well for this task.
-
How much to trim?
-
Just enough to allow installation of the spacer.
-
Alternately, you can bend out the outer lip of the UCA with a 2-4 lb.
sledge hammer.
 |
| Ball Joint Spacer Installation |
-
Put the spacer in place, NOTCH FACING DOWNWARD and, using a floor jack
to control arm height, align the ball joint and install the hardware.
-
The notch acts as a weep hole to let any water that gets in from above
drain out to prevent the ball joint from rusting out.
-
Tighten ball joint hardware to 25 ft.lb. or 35 N.m.
-
Note: Apply this torque to the allen head bolt and the Grade 10.9 nut
only, then install the 2nd nylon lock nut and tighten it down snugly in
order to lock the first nut in place. No need to toque the nylon lock
nut to 25 ft.lb. value, it may strip.
-
If you wish, you can spray the exposed head and threads of the bolts
with some paint, as the black oxide coated hardware may tend to rust
over time.
-
Extend the shock to see if it needs shimming. (it likely will)
-
Place the appropriate number of washers to ensure the shock does not
limit down travel.
-
Tighten shock hardware.
-
Repeat for other side.
-
Re-install the wheels.
-
If the end of the upper control arm is too close to the tire at this
point, there are several options:
-
You can try and grind off part of the outer lip of the control arm
(area at the left edge of the red circle in the photo above)
-
You can add a 1/4" wheel spacer to move the wheel/tire away from
the suspension.
-
You can swap to a narrower tire, for example changing from a 33x12.50
to a 33x10.50 tire will move the inner edge of the tire away from the
control arm since it'll have less sidewall bulge on the same wheel.
-
You can swap to a wheel with less back side spacing, for example going
from a 4.75" to a 4.5" backspaced wheel will move the inner
edge of the wheel and tire 1/4" away from the control arm (stock
wheels are ~4.75" backspacing).
-
Put the vehicle back on the ground.
-
For low profile bump stops only:
-
Shim them approx. 1/2" with some washers or use stock bump stops.
-
Failure to do so could result in damage to CV joints, shocks, or other
components.
 |
| Shimming for low profile bump stops |
-
Even with stock bump stops, you may experience some CV axle binding.
-
To check, let the suspension hang at full droop.
-
Easy to do this when you finish installing the spacers, as the front
end should be up in the air.
-
Rotate each CV axle shaft by hand and check for any binding at the CV
joints and also check with the wheels turned to the steering stops in
each direction.
-
Also, you may want to feel the CV axle rotation before installing the
spacers, just to familiarize yourself with what they feel like
"normally".
-
If felt, several options to fix it are available:
-
Add some shims as shown above for the low profile bump stops.
-
Or install a front
differential drop kit to lower the differential and
thus lessen the CV joint angles.
-
Re-adjust torsion bars, if needed
-
If the ride height is what you want it to be after installing the ball
joint spacers, there is no need to make any adjustments.
-
There are good instructions on the
4x4Wire.com Toyota page. and a separate
write up on the OffRoad.com Toyota page:
In short:
-
Spray the torsion bar hardware with a penetrating lubricant.
-
Wipe all debris off of the threads.
-
Spray them again.
-
Jack up the front to unload the bars.
-
Adjust them with a 22mm wrench.
-
Lower the truck.
-
Bounce the front end and roll the truck back and forth at least 10
feet.
-
Repeat until the front is level and at desired height.
-
The measurement between the fender lip and edge of rim should be about
15 - 15.5".
-
This would be the case for 1.5" lift, stock height is 13.5" -
14".
-
-
It has been observed that some driveway alignment adjusting is
beneficial and easy to do.
-
Following these simple steps will make life easier for the alignment
tech who, to be honest, might not be prepared for a vehicle that is any
other than bone stock and only slightly out of alignment.
-
First make sure the ride height is set to where you want it.
-
If not, adjust it with the torsion bar adjusters
-
Loosen the adjustment cams on the lower a-arms making a note of each
bolt's orientation.
-
Move the lower arms outward until two things happen.
-
(It will likely be necessary to lift the front end while adjusting and
roll the truck forward and backward after each adjustment.) One, the
tires appear vertical.
-
Two, all cams are adjusted to mirror those on the opposing arm and in a
position *closely* relative to where they started. (It is more
important that the tires be vertical than the hardware be exactly
relative to it's originating position)
-
For example, if the driver's side front cam is pointing straight up and
the driver's side rear cam is pointing outward, the passenger side
front cam should be straight up and rear outward.
-
If, before adjustment, say the rears were angles outward 30 degrees
more than the front, after adjustment the rears should still be outward
about 30 degrees. Again this is not as critical as trying to get the
tires vertical.
-
Adjust the toe by loosening the adjusters and rotating.
-
It is a good idea to lock the steering wheel in a straight position.
-
What you adjust to one side, do to the other. Typically about
.5-.25" of toe is fine.
-
If you have trouble measuring, simply attempt to get them straight or
angling in slightly.
-
You'd be surprised how close one can get these measurements with just
the eye.
-
However, perfection is not necessary, this will simply get you in the
ball part and help to avoid the "blank stare" when an
alignment tech sees his numbers are out and doesn't know which nut to
turn which way. (you'd be surprised how often this happens with 4X4s)
-
You should recheck the height after this.
-
If you find you adjust the height severely, which is unlikely, and the
tires are clearly off (by the eye), repeat these steps.
-
Here
is a link to a description of a driveway alignment procedure
-
A visit to an alignment shop is definitely recommended!
-
You may need to shop around for a good alignment shop as some may tell
you they can't align the truck because it is "modified".
-
Don't be "wowed" by the shop with the fanciest computerized
equipment, either. You may find the technicians at such shops may throw
up their hands if the computer says the alignment is too far out.
-
Look for a local "mom and pop" shop when they will actually
understand how to align the front end and are willing to work with the
available adjustments and make it work. There should be adequate
adjustment range in the front suspension adjusting cams to handle the
ball joint spacers and changed ride height, assuming the front end is
not damaged.
-
Re-check hardware torque in 2 weeks.
-
If you find problems with your CV joints binding due to the steeper
angles or find the CV joint boots rubbing and wearing out faster, you
might consider adding a front
differential drop kit.
While not really related to ball joint spacers (or a front differential
drop kit), many owners find that replacing front CV axle half shafts is
a difficult process. Mainly this is due to the tight location in which
the axles are installed. Often, you can loosen the lower ball joint
clamp and swing the lower control arm out of the way (disconnect the
front sway bar if installed) and then swing the spindle/hub up out of
the way for more clearance when removing or installing the CV axle.
Here is a write-up on a simple modification that can help in future
replacement that involves replacing the differential output flange
studs with bolts:
[Return to the top of this page]
-
Block the rear wheels and place the front end of the truck on jack
stands and remove the front wheels.
-
Let the front suspension fully droop, tire should spin freely.
-
Loosen ball joint hardware, ball joint will drop off of the arm (photo
A below)
-
Remove old ball joint hardware
-
Place spacer on top of the ball joint, slowly lower the jack to assist
in lining up bolts with the hole (photo B below)
-
Tighten bolts in an X pattern to assure proper tightening torque.
-
If you wish, you can spray the exposed head and threads of the bolts
with some paint, as the black oxide coated hardware may tend to rust
over time.
-
Do the other side.
-
Lower vehicle.
-
If you decide to crank the torsion bars, do so now.
-
If you decide to shim the shocks, do so now.
-
Get an alignment.
-
Check tightness of bolts after a week.

For the upper control arm (UCA) brace, you want to bolt it on top of
the UCA with the 4 ball joint bolts. Then in the remaining holes (4 in
total), mark and drill holes through the UCA to accomdate the supplied
8mm bolts and then bolt the brace on top of the UCA.
