Front Axle Bearing Replacement
 It
sure is cold in the shop today. Crank up that space heater, and get the
mercury to stop hiding in the bottom of the thermometer. Hard to believe
your tools can get that cold, huh?
Well, let's dig into
your first repair order. It's a 1995 4Runner with a loud howling or screeching
noise coming from the front end, heard while driving at any speed in 2WD
or 4WD. The customer says it really got bad when the temperature dropped
down into the 30s.
NOTE: Applicable only for 4X4 Trucks, 4Runners and T-100 models produced
after August 1989
That noise your customer
hears may be from the front spindle bushings. A new needle roller bearing
and thrust bushing are available for use in place of the original bushing.
This is a viable upgrade anytime you need to replace the stock factory
bushings.
 Here
are the details: INSTALLATION
PROCEDURE
1.Remove the front axle bushings.
2.Install the needle roller bearing using Toyota Special Service Tool
# 09620-30010, tool # 5 or equivalent bearing driver.
3.Install
the thrust bushing using the appropriate bushing driver/installer.
 4.Apply
grease, Toyota Part Number 08887-80219 or its equivalent, in the following
locations:
- Thrust bushing
inner bore and frontal surface.
- Oil seal.
- Drive shaft where
contact will be made.
Note: One
tube of grease is sufficient for both left- and right-side axles. Reassemble
the knuckle and driveshaft assembly. Use care when installing shaft
to prevent damage to needle roller bearing.
PART NUMBER INFORMATION
After you have re-assembled
everything, put the wheels on and torque the lug nuts. Hop in and stomp
the brake pedal a few times. Remember the last time you didn't do that
after having the calipers off? The pedal went to the floor; the  vehicle
didn't stop, but your heart almost did! Test-drive the vehicle again to
make sure the customer's complaint has been solved.
Isn't it great when you can provide the customer with a modification that
can solve their problem now and avoid a future one as well?
