Steering Rack Fluids

[smt 59]

Hi Folks,

I was at the dealer yesterday having my intermediate steering shaft looked at( they cannot confirm or deny if it needs replacing) and the tech. mentioned to me about the racks power steering fluid in other models being replaced with ATF instead of PS fluid as it eliminates the seal noise and is better for the system, it is a GM bulletin for other models.
My question is has anyone heard of this practice and or done this? by the way my ISS only annoys me at higher speeds, minor clunking that cannot be heard just felt in the steering wheel.

People call it the "STEALERSHIP" for a reason.


But yes, it's not uncommon. It's debatable, and on some car forums a hot topic of personal opinions. Always double check for a manufacturer bulletin.

Great thanks Mikekey, I have no reason to change that fluid as I have recently done so, I guess because they could not sell me on the other main reason I was there they would try. Little do they know that I am fully aware of how the dealship works(at trying to open my wallet)
