2. Turn the steering bicycle from lock to lock (without hitting the stops) several times. This will help warm the fluid to operating temperature so that you become a more accurate reading.
3. Turn off the engine.
4. Remove the cap from the reservoir and read the fluid level at the dipstick attached to the cap (look for the HOT and Common cold marks). On other models, you may see markings on the side of the reservoir to aid you check fluid level.

5. If necessary, top off the system with the fluid recommended by your car manufacturer. Consult your car owner's manual or vehicle repair transmission.

iii. Pinion Gear Associates Leaks

Seals and O-rings are the main culprits on pinion gear leaks as well.

If yous've plant a leaking indicate around the coupling associates, you may need to replace:

• input shaft seal and valve assembly kit
• torsion bar O-ring

Keep in mind that leaking pinion seal may show upwardly as a leak around the bellows. This is hard to distinguish from other seals in the rack assembly.

Tip:

Replacing the steering rack and pinion gear with a new unit is a much amend option because of the labor costs of rebuilding an one-time unit simply to set up a leaking pinion seal.
