Beretta V6-173 2.8L (1989)
Some power steering gear assemblies are being replaced unnecessarily when a small amount of power steering fluid is found in the boots. Small amounts
of power steering fluid in the boots should not lead to gear replacement unless the customer has had to add power steering fluid to the system on a
regular basis and/or has commented about external leakage of fluid.
If a customer has commented about having to add fluid and/or external leakage of power steering fluid, there should be a substantial amount of fluid in
the boots. This condition would indicate that the steering gear should be replaced.
NOTICE:
When adding fluid or making complete fluid change, always use GM power steering fluid, part number 1050017 quart, or 1052884 pint (or
equivalent meeting GM Spec 9985010). Failure to use the proper fluid may cause leaks and may damage hoses and seals. The use of any
form of Automatic Transmission Fluid is not recommended.
Looseness at Pinion Pin (See Special Policy Bulletin - Temporary Reduction of Power Steering Assist When Cold)
Some power steering gear assemblies are being replaced unnecessarily due to mis-diagnosis of pinion pin looseness. The pinion drive pin is designed
with a small
amount of clearance to the spool valve hole. As a result, a small amount of movement can be felt when the pinion-valve assembly is examined.
The drive pin should be carefully examined for damage under sufficient lighting conditions. If the pin is found to be broken, then a service "short" gear
assembly must be installed in the vehicle.
