NOTE: misting/ dampness around the input shaft seal can be mis-diagnosed as leaks (see top four
pictures with ',/');this is normal. Suspected leaks (' X ') should always be verified by cleaning and
chalking.

Fluid Misting / Dampness Around Pinions and Bellows
•

'Misting' or a damp area may be commonly seen around the steering gear pinion tower seal and the steering
gear bellows. This is normal and occurs on most hydraulic dynamic seals due to their design and is not a reason
to change the steering gear, nor does it indicate the part will fail early or later in life. If there is a suspicion of a
leak, then normal procedures using cleaning and chalk should be employed.

2. Joint 'Dnocks': Mis-diagnosis

•

A considerable number of steering gears are unnecessarily changed due to mis-diagnosis of play in joints. It is
very uncommon to cause play in gears (can be created from hard accidents), but joint play is regularly misdiagnosed as steering gear backlash rather than play in ball joint or column joints. Carefully following Diagnostics
and Testing (see TOPix Workshop Manual, section 211-02) for the steering linkage will help isolate the failed
component.

3. Pump Failure: Mis-diagnosis
•

A considerable number of steering gears are unnecessarily changed due to pump damage leading to blanket
repairs. The most common reason for steering system noise is damaged pumps. In most cases this is caused by
system leaks (low fluid leading to cavitation), grit contamination during top-ups, or holding the steering on full
lock too long. In these cases, it is critical to make sure there are no leaks in the system that may cause further
failures. However, the majority of these issues can be diagnosed using Diagnostics and Testing (see TOPix
Workshop Manual, section 211-02) for pressure testing and if required flushing the system and changing the
pump.

4. Bellows - Holes
•

If a steering gear fails -- particularly with rust and grit found inside the bellows -- it is important the bellows are
carefully checked for holes and perforations. Steering gears are not warranted for this type of failure.

5. Bellows - Incorrect Use of Cable Ties
•

Commonly, after joints have been inspected cable ties are used to try and re-seal the boots. This is ineffective
and normally leads to further steering gear failures. All clips are available as lower level service parts and should
be used after removal of a boot.

6. Incorrect Level of Repair
•

Often incorrect levels of repair are made on steering gears. The parts catalog should be inspected to identify
what is available along with correct level of diagnosis. Commonly missed parts that may be used are, transfer
pipes, feed & return pipe a-rings and inner ball joints.
