CAUTION:Power Steering Assist Motor Bolt (1) - Install NEW and tighten [4x] - Fastener Specifications
Connect the electrical connectors. (1)
- Using a digital scale, weigh the NEW electric belt drive rack and pinion steering gear belt. Record the weight and use the chart to determine the tension of the electric belt drive rack and pinion steering gear belt. Refer to the Belt Tension Table for proper belt tension specification.
Electric Belt Drive Rack and Pinion Steering Gear Belt (1) - Install NEW
- NOTE:
With the steering linkage inner tie rods removed, there is no stop on the end of the steering rack travel.
Install an appropriate tool (1) on the input shaft (2) and rotate the input shaft as close to end to end travel as possible 3 times to manually break in the electric belt drive rack and pinion steering gear belt.
- Ensure the electric belt drive rack and pinion steering gear rotates freely.
Move the steering rack to centered position. The center position can be found by taking a measurement of the distance (a) from the end of the steering gear housing to the end of the steering gear rack (1). This measurement should be 61.1 mm (2.4 in).
To adjust the belt tension, loosen the steering gear idler pulley (4) and use the tool installed to adjust the belt tension as necessary. Tighten the steering gear idler pulley (4) when taking measurements.
- Install the CH-53104 Steering Gear Idler Pulley Holder (2).
- Install and tighten the 2 power steering assist housing bolts (3).
- Install an appropriate sized C-clamp (1) with a rubber pad on the tightening surface to tighten the steering gear idler pulley to the correct specification.
- Place the body of the GE-50576-A Acoustic Belt Tension Tester on a flat surface.
Position the microphone of the GE-50576-A Acoustic Belt Tension Tester (1) at the outboard location of the electric belt drive rack and pinion steering gear belt (2).
- Use an allen wrench or finger to strum the steering gear belt at the center location between the two pulleys three times to get an average belt tension reading.
- Record the average reading from the outboard frequency test.
Position the microphone of the GE-50576-A Acoustic Belt Tension Tester (1) at the inboard location of the electric belt drive rack and pinion steering gear belt (2).
- Use an allen wrench or finger to strum the steering gear belt at the center location between the two pulleys three times to get an average belt tension reading.
- Record the average reading from the inboard frequency test.
- Find the average of the inboard and outboard measurements and compare to the chart. If the frequency is within specification, continue. If not, repeat steps 14 - 20 until accurate frequency specification is achieved.
- Apply the final torque for the steering gear idler pulley before removing the tools. Fastener Specifications
- Remove the C-clamp used to tighten the idler pulley.
- Confirm the inboard and outboard measurements are still within specification. If not, repeat steps 15 - 21 until accurate frequency specification is achieved.
- Remove the GE-50576-A Acoustic Belt Tension Tester.
- Remove the 2 power steering assist housing bolts used during the belt tension procedure.
- Remove the CH-53104 Steering Gear Idler Pulley Holder.

Install a rubber pad to the tightening surface to prevent damage to the idler pulley.
NEVER hold the tester by hand while taking measurements or the readings will be inaccurate.
Never use a sharp object to strum the belt as belt damage may occur. If the belt is damaged, the electric belt drive rack and pinion steering gear will need to be replaced.
Strum the electric belt drive rack and pinion steering gear belt as close as possible to the center position between the two electric belt drive rack and pinion steering gear pulleys to achieve the most accurate readings.
When testing frequency, there should be a difference of 10 - 40 Hz between the inboard and outboard measurements. If you are not seeing a difference in the measurements, rotate the electric belt drive rack and pinion steering gear 90 degrees and try again.
Increasing the belt tension increases the frequency. Reducing the belt tension reduces the frequency.
