LaCrosse V6-3.6L (2007)
drops of oil leaking, carefully inspect the power steering hydraulic system. The inspection should be performed while the engine is running and the
steering wheel is rotated from lock to lock. If a leak is observed, then repair the source of the leak.
If the noise is not the result of low power steering fluid, provide a complete description of when the noise happens and what type of noise it is; i.e.
squeal, pop, clunk, tick, continuous rubbing, etc. If it is a pop or clunk noise, make sure you inspect the convoluted boots to determine if the inner tie rod
is rubbing the boots. Replace the boot or boots only for this condition. If the noise is a clunk or pop noise and it's not the inner tie rod rubbing the
convoluted boots, make sure to inspect the intermediate shaft for the slip stick condition. This should be done prior to replacing any steering gears.
If amber/yellow tinted glasses and the "pen light" style of black light are used, the lithium in the grease will show up in greenish/yellow similar to the
greenish/yellow dye used by many dealerships to test for leaks. Always use the black light recommended by GM Tools and clear glasses to inspect for
dye in fluid leaks.
If the source of the leak cannot be found by visual inspection, add dye, P/N 88861206 (in Canada, use P/N 88861259), and inspect the system using
Black Light (J 28428-E or J 42220).
The number of vehicles that will require a complete inspection using dye will be minimal based on the inspection of numerous steering gears returned for
testing where the complaint was fluid leak and no leaks could be reproduced.
If a steering gear is replaced because a leak was discovered using the dye test method, make sure the repair order has a description of where the leak was
discovered. If the steering gear is replaced for a noise concern, make sure a complete description of the diagnosis appears on the repair order as
described in Step 5 above. Steering gears replaced under warranty will continue to be on parts return and regional feedbacks will be processed on any
gears which the customer complaint cannot be verified. Over 90% of all steering gears inspected have little or no explanation of the condition, the
technician's diagnosis or reason for replacing the gears and/or did not have any indication that dye was used to find a leak.
