Tools required:Description and Tool Number
Bearing Cup Replacer ... D79P-1202-A
Spacer Selection Tool ... T87C-11O4-B
Disassembled View:
1. Install the bearing races in the steering knuckle using Bearing Cup Replacer D79P-1202-A or equivalent.
2. Install the bearing and preload spacer in the steering knuckle.
Install Spacer Selection Tool:
3. Install Spacer Selection Tool T87C-1104-B in the steering knuckle and clamp the tool in a vise.
4. Tighten the center bolt in increments to 49, 98, 147, and 196 N.m(36, 72, 108, 145 lb-ft). After tightening, seat the bearings by ROTATING the steering knuckle. Verify torque of center bolt is 196 N.m (145 lb-ft).
5. Remove the tool/steering knuckle from the vise.
6. Mount the steering knuckle in a vise, clamping it where the shock absorber mounts.
7. Install a socket and N.m(lb-in) torque wrench on the space selector tool.
8. Measure the amount of torque required to rotate the Spacer Selection Tool T87C-1104-B using a torque wrench. The torque wrench reading must be taken just as the tool starts to rotate.
a. If reading indicates 0.25-1.8 N.m(2.21-10.44 lb-in) the spacer is the correct thickness.
b. If reading indicates less than 0.25 N.m(2.21 lb-in) a thinner spacer must be installed.
c. If the torque wrench indicates more than 1.8 N.m(10.44 lb-in) a thicker spacer must be installed.
Bearing Spacer Thickness Chart:
Each bearing spacer has been assigned a numerical code that identifies its thickness. The code is stamped into the outer diameter of the spacer. The numbers range from 1 to 21 with 1 being the THINNEST spacer.
Measure The Spacer With A Micrometer:
If the number is not legible, measure the spacer with a micrometer and compare it to the chart to determine which number it is.
Changing the spacer thickness by one number, either higher or lower, will change bearing preload by 0.2-0.4 N.m(1.7-3.5 lb-in).
EXAMPLE A: Bearing preload TOO LOW-THINNER spacer required.
(1). Measured Preload: 0.15 N.m(1.32 lb-in).
(2). Spacer Thickness: 11.
(3). Required Spacer: 9.
A change of two will change bearing preload by 0.4-0.8 N.m (3.4-7.0 lb-in).
2 x 0.2 to 0.4 = 0.4 to 0.8.
(2 x 1.7 to 3.5 = 3.4 to 7.0).
Example:
When added to the existing preload, the measured preload will now be 0.55 to 0.95 N.m(4.72 to 8.32 lb-in).
EXAMPLE B: Bearing preload TOO HIGH-THICKER spacer required.
(1). Measured Preload: 1.9 N.m(16.82 lb-in).
(2). Spacer Thickness: 7.
(3). Required Spacer: 11.
A change of four will change bearing preload by 0.8-1.6 N.m(6.8-14.0 lb-in).
4 x 0.2 to 0.4 = 0.8 to 1.6.
(4 x 1.7 to 3.5 = 6.8 to 14.0 lb-in).
Example:
When subtracted from the existing preload, the measured preload will now be 0.30-1.10 N.m(2.82-10.02 lb-in).
After selecting a spacer, verify the bearing preload using Spacer Selection Tool T87C-1104-B.
9. Install the brake rotor/wheel hub assembly.
